Sparkplug is a fighting game for the PC. It stars an original cast of 20 robots and cyborg characters in a shady battle competition, led by one of the robots themselves, Operative, who apparently built the battle arenas, and all of the other robots. The game has many different battle modes, and in general feels different from most other battle games, since it incorporates some elements of racing games. Sparkplug is mostly child-friendly, but it is still rated E10+ because of the lore behind the game, which is pretty dark compared to the rest of the game.


The story is one of the largest parts of Sparkplug. It follows two of the game's characters, Doormat and Cooler, who woke up in the main arena's sewer and are now trying to figure out the secrets behind Operative, CeROBral and the other robots.

More information at Sparkplug/Story.


Sparkplug is a 3D fighter, but innovates in that field. Instead of taking place in simple arenas, the game takes place on large arenas similar to racing ones; long, and with many rooms. Some maps are more open, but most of them are closed and are almost maze-like. Some maps are even like parcours in that you have to dodge obstacles and jump to reach other areas.

Each of the characters has 4 stats, that changes how they fight: Health determines how many hits a character can take before being knocked out. Attack changes the power of a character's attacks. Defense affects how much damage attacks sent on the character will deal. Finally, Speed will make a character faster or slower. Often, a character will have a lot of Speed and Attack, but low Health and Defense, or the opposite. However, this is not always the case; quite a few characters are bulky with high Defense and Attack, but are slow, too. Health eventually regenerates, so one doesn't have to worry too much about being damaged.

Stats aren't the only factors that change a character. Each character has a basic punch attack, but also 5 other "special" moves. Some characters have a special attribute or two instead; for example, Nuclear starts with double stats, but as time flies by, its stats eventually become half of a normal character's.

Game Mode: Escape

The main game mode combines Racing and Fighting into one. At some points in the map, you will get blocked by doors; which only open when a set number of characters are knocked out. You must survive and knock out the other robots in order to get to "The Room". Once you enter the room, you win; but only 1 robot can enter the room at the end. It is pretty hard to get to The Room when you begin playing, but as players get more experienced, it gets easier and easier.

Game Mode: Arena

Players who like more traditional battling can enjoy the Arena mode, which is the other game mode in the game. "The Room" is removed, while maps are changed to be slightly more open. Additionally, the doors around the arenas are now always open, and it's always possible to go both ways. The game is an elimination match, which means once a character blows up, it won't respawn.

Mode Twists

When playing one of the two game modes, one can enable "Mode Twists". Mode Twists affect the way the game plays, usually in a pretty drastic way. Mode Twists can combine into bigger modes, so for example, the "Speedy" and the "Race" twists on Escape can combine into a "Speedy Race Escape". There are a total of 15 Mode Twists: 8 for Escape and 7 for Arena. You can choose to make the Mode Twists randomly generated, or to choose the mode twists yourself. While you can put as much mode twists as you want yourself, Mode Twists will never be randomly generated with more than 3 twists at once.

Name Base Mode Description
Speedy Escape Boosts the speed of the characters. This makes the mode end quicker, notably. One can notice fast characters are slightly less boosted then slower robots, making the gameplay more balanced.
Race Escape Makes everyone the same speed and removes moves, stats and attributes, effectively making all characters the same besides appearance. Some characters are shrunk to balance gameplay further.
Volcanic Escape Makes lava slowly advance behind the players. This acts as some kind of timer, putting pressure on players. Lava instantly kills frailer characters and doesn't take long to knock out bulkier ones.
Glass Wall Escape A large glass wall blocks players from advancing. This glass wall slowly advances itself. This glass wall prevents the player from finishing the mode too quickly. The wall goes two times as fast if Race is in place too.
Mine Escape Lets each player place one mine somewhere on the map before the round. This adds an element of unpredictableness to the game, and forces players to be careful. Mines usually don't KO characters right away, however.
Balloons Escape Each player gets their Attack doubled. Here's the catch, however; players get 3 balloons on their heads, and when they die, 1 balloon pops. The other balloons stay on their heads. They get killed for good once all are popped.
Moving Forwards Escape Forces players to walk constantly. This makes fighting harder, and basically prevents camping even though it's impractical here. This twist can be hard to be used to at first, but most players eventually manage to get used to it.
Boss Escape Players have to fight a Boss before entering the final area. In case of the game mode being Race, the Boss will automatically destroy itself after a few minutes, making it more of a survival course.
Disaster Arena Causes Disasters to attack the arena. One example of such disaster is "Flood", where the robots have to get to high ground if they don't want to drown. A list of all disasters can be seen below.
Enemy Arena Makes waves of enemies attack the robots. All enemies specialise in a stat or a kind of move. For example, the "Beeee" is very fast, but doesn't attacks, being only a distraction and sometimes an attack sponge.
Respawn Arena Changes the arena into a deathmatch instead of an elimination. Players have to knock out as many other robots as possible to win, instead of being the last one standing. Thus, players can respawn when knocked out.
Coin Flip Arena Each minute, a giant coin is flipped next to the map. If the result is heads, the player with the least health left is fulled healed. If the result is tail, however, it is knocked out instead. This adds some panic to the game.
Monster Arena One player is randomly chosen as the monster, and becomes the only player able to attack. It has to kill all the "innocents". But there's a time limit and the innocents win if the monster doesn't kill them fast enough.
Coins Arena Makes a bunch of coins spawn in the arena. Players have to get as many coins as possible. The player with the most coins wins at the end of the round. Players drop all their coins when they die, so they can't abuse it.
Boss Arena Makes a boss spawn in the arena. Some players like to team up to beat the boss, but other players prefer to fight the boss without teaming up. Some disasters are particularly dangerous here.


The game has 20 different characters, each with their own stats, flavor and moves. All characters have stats, which always totals at 100. They all either have 5 moves. However, up to two of those moves can be turned into "Passive" attributes instead. 18 characters are revealed thus far:

Tier List

The various characters in the game are mostly balanced, meaning almost all of them can be used successfully, but some are just better then others. Characters are not ranked by number, but by this order: Great - Good - Ok - Bad. This section of the page shows the tier list, with reasoning:


  • Dreadgon: One should be thanksful for Dreadgon's slow speed and large size, because Dreadgon would be broken otherwise. He can OHKO most characters with a Ire of Appaling + Massive Bite combo, which is even more effective if Roar of Terror is used before.
  • Operative: He has very good offenses, decent speed, and better bulk then frail characters like Doormat, which give him good longetivity combined with his move Debug which lets him recover. His ability to turn invisible makes him even better as he can sneak behind foes, then hit them hard.
  • Emit: She is a very strong character with a wide range of powerful moves. She is rather slow but can easily boost herself forwards with Azure Rocket. While she has low defense, her Health makes her bulky enough to last for a good time.
  • Hydro: Her diverse movepool and her balanced stats make her a very good pick. She can reliably recover thanks to her passive, and can attack enemies no matter what the direction. She's a little slow, but that's her only real flaw.
  • Doormat: Despite his lack of projectiles, Doormat's decent offense and very high speed make him a great character to use. His range problem can be fixed with the use of Dash Slash, and since he's the fastest character, no one can outrun him. He has trouble hitting Navexte and Zéro though.


  • Time: Time is frustratingly hard to play, both with and agaisnt, due to his time gimmick. If you do not know him well, you will struggle agaisnt him. He can blind others with Blind Ray. Both of his attacks also hit very hard. However he is rather easy to whittle down with projectiles.
  • Incinerator: While he's slow, he hurts incredibly hard and has decent bulk to boot. His ability to pose landmines and then make them explode makes him a very dangerous character. He also has a strong projectile in Missile and a good melee attack in Flamethrower.
  • CeROBral: CeROBral is a balanced character, even if he's a little slow. CeROBral is mainly known for beign a good counter to Doormat, as he can stun him and push him away, then set up on him and OHKO him with a strong Power Orb. Additionally, Operative can't sneak on him.
  • Nuclear: He can cause utter carnage at the start of a round, dealing very strong attacks, and actually outspeeds Doormat at the start of a round. However, he becomes horrible near the end and he has little to no longetivity.
  • SentROB: SentROB has nicely balanced stats, and is very unpredictable thanks to his fifth move allowing him to swap between two movesets. However, he is poor defensively, lacking a recovery move, and additionally has trouble fighting faster enemies since most of his strong moves are slow.


  • Microwave: Ever since she was added, Microwave is considered the best defensive character in the game. Microwave has incredible defenses, and can heal very quickly. She can easily run with Deliver Mode and can slowly destroy foes with her Passive, Bake.
  • Navexte: Navexte has decent bulk and great speed. She is also able to heal, and can boost her attack. The problem is that her heal consumes her attack boosts and she has a terrible attack stat. Her ability to fly makes up for this, though, as it makes her the hardest character to hit.
  • Solar: Solar is a defensive character, but defensive is rarely a good playstyle in Sparkplug as most defensive characters are bad offensively, and that happens to be the reason Solar isn't considered a Great character. However, he's able to make damage with his ability Growth.
  • Cooler: Like Solar, Cooler is defensive. Cooler can't do much damage, but he can slow down foes which is definitely an useful ability. He's also able to do decent damage despite his low attack stat. His big flaw comes from the lack of a reliable recovery, making him a bad wall.
  • Miss CO2: Miss CO2 has high Health and can do very high damage, but she's slow and her defenses are bad. This makes her very vulnerable to attackers such as Incinerator. Additionally, she doesn't always poison enemies with her attacks, meaning her attacks end up beign rather weak.


  • Mr. H20: Mr. H20 is fast and can be annoying with his attacks, but his good traits end here. He's not very bulky, and can't deal much damage. However, his mobility is undeniably great, and he's definitely the best "Bad" character. So if you want to play any Bad character seriously, use him.
  • 2-ME: 2-ME is a very annoying character, but besides that, you'll find out he simply can't deal damage to foes effectively. He can survive for a while but at the end of the round, he has a lot of trouble finishing the enemy. His defenses are also passable at best. All in all he's not a good character.
  • Watchword: Watchword is the worst wall in the game despite having the highest Defense. He simply can't hurt foes, and doesn't haves a reliable mean of recovering besides a very basic and weak attack that barely helps him anyways. His ability is also completely useless competitively.
  • Zéro: Zéro is terrible, as she has only 1 point of HP. Even though she does a lot of damage, she is forced to rely on ERROR 0 and Condensation because her melee attacks make her too vulnerable. While she is very fast, several characters are at the same speed or outspeed her.


Each character has a figurine associated with them. In order to get a figurine, you need to do a challenge which usually requires you to play as that character or do something related to them. Unlocking a figurine lets you unlock the skin associated with that character. These are split in "waves".

Skins are pallette swaps of the characters in the game. They are unlocked by getting figurine; each figurine unlocks a certain skin. With the skin comes a certain small change in a character, for example 1 stat being stronger and another being weaker, or a move getting replaced with another. However, while this change is based on the skin, the player is free to give a certain change to the normal skin, and is also free to not use the change while playing as a certain skin.

Name Description
Base Sewers The junkyard of the base you spend most of the story on. Despite the name, it's actually above the base, despite it beign very impractical. Operative just makes terrible design choices... The map is very linear and also quite small. You can risk a stroll into the water below, but it is rarely advantageous.
Base Arena The main arena of the game, and probably the one you'll spend the most time in. It is one of the simpler maps in the game, and is built in such a way both the Escape and the Arena gameplay can work smoothly. This is the only arena to be fully robotic, and thus features no "terrain".
Martian Desert There are no martians here, don't worry. This desert is clearly at the north of Mars considering the presense of snow in the background. This map is one of the least linear maps, not only in shape but also in terrain; many rocks, some of them beign tall, pop out of the ground, and the sand is also very hilly.
North Pole How come nobody noticed the base Operative set up here from satellites or something? This map is strange as it gives you two options for how to proceed; you can enter enter a rather large open map, which is longer but safer, or go through a very thin passage which leaves you open to attacks.
Europa Sea Operative managed to prove there is indeed an ocean under Europa's crust. How did he even get a base here anyways? This arena is very open, and is actually the only map where multiple people may reach The Room. But there's a catch: there's an oxygen meter here and nearly all of the map is flooded with water.
Asteroid Arena This arena is actually rather linear, but it's nature forces you to jump around a lot. Be careful to not fall off the map as that is a one-hit knockout. It takes place on a lot of asteroids. Most of them are rather big. There are a few "rest points" in the arena that are mechanical bases, but otherwise you must constantly be mobile here.
Lunar Base A rather linear map similar to Base Arena, but a lot more sci-fi esque, with many windows giving out views of parts of the moon and space. Various conveyers carrying stones can be seen. One can ride these conveyers. This map actually has a few secret "Moon Caves" that can be explored and serve as shortcuts.
Ruined Residence This map could've looked like a nice place to live in if it wasn't for the fact it was completely ruined. Cobwebs can be seen in the corners, mold can be seen on the walls, some of those walls are broken, and so on. It has a somewhat maze-like layout with several alternate paths to choose from.


Name Description
Flash Flood Causes water to quickly flood the arena. Water deals damage very quickly if you're inside of it, so it's best to go to high ground as fast as possible if this disaster happen.
Power Outtage Causes everything to go dark (even if you're in an open arena like Martian Desert). All players are unable to see anything during this disaster. Particulary dangerous if the Enemy twist is present too.
Bomb Rain Causes time bombs to rain from the sky. Once on the ground, it counts down for 3 seconds before exploding. Be careful when this disaster happens and you will most likely survive.
Vacuum Error Causes some kind of error in the arena which makes everything forced to go towards the center of the arena. Don't ask how that happened. Not really dangerous, but can be annoying.
Wind Outbreak Causes a lot of wind to break inside the arena. Causes damaging tornadoes to pop up around the arena and pushes entities in random directions. This disaster can be very irritating at times!
Lightning Issues Causes thunderbolts to strike at random places. The thunderbolt one-shots all robots but the chances of getting hit by one are rather slim.
Acid Waves Causes acid waves start flooding the area. Players have to jump above the acid waves as they come in order to survive. This often interrupts battles going on before the disaster.
Flawed Temperature 1 Causes the ground to freeze, making everything slippery. This can be annoying at best but is never really dangerous, unless the arena has hazards in it.
Flawed Temperature 2 Causes everything to heat up, lowering everyone's stats (except Health, of course). The only really noticeable effect of this is speed, though, because the Attack and Defense nerfs cancel eachother.
Glitch! Causes everyone's health bar to be halved, effectively bringing everyone to at most half their health. If they already have less then half of their HP, the health bar's halving doesn't affects them.


There are 15 enemies in the game:

Name Specialises in: Description



Speed Beeee is the smallest enemy, and it's seriously way too fast, having double of Doormat's speed. Yep, that means it has...100 base speed! It can't attack but it will probably block a few of your attacks unintentionally.



Melee Attack Definitely a fan of heavy metal considering the name and the helmet, this robot is rather fast (but not as much as Beeee). It attacks using the spikes on it's helmet. Basically, it's an enemy version of Doormat.



Ranged Attack A cool name for an honestly pretty strange robot. This enemy floats in one place and shoots light orbs at the player robots. Occasionally, they will rocket into the sky and re-appear somewhere else.



AoE Attack This small rocket falls down from the sky until it almost reaches the ground, where it will rocket up very quickly causing an explosion. It also explodes once it's destroyed, so just stay away from it if you don't have a projectile.



Defense A wall of bricks with robot legs. I'm serious. This thing just wanders around. Occasionally, it may try bumping into a player to make them trip. They have very high defenses but they're not very threatening.



Dash He saw you, so now he's trying to attack you! He attacks in a way similar to Wheelies from Kirby in that it rolls towards any robot it sees. Except other enemies, of course.



Spawning A gigantic hammer robot with quite a lot of HP. It isn't as bulky as Wall-O-Brick though. It occasionally mashes the ground, creating a hole from which a Minihamma pops out. This whack also deals a lot of damage.



Being Spawned These small hammers are spawned by Maxihamma. They simply attack with a swing of their head, and are quite easy to beat as they are slow, frail and don't have projectile attacks.



Laser Greeneen pretty much loves the color green. It's even said to keep a collection of green things it found. Even it's laser attack is green. That laser follows you like a laser pointer, dealing damage.



Poison A rather stubborn robot that shoots small toxic bubbles from it's mouth. These bubbles do not damage you, but they poison you dealing damage over time, so they're still dangerous.



Freezing Cry-O-Cryo is mad at people that mispell Cryo and attempts to freeze them, even though there is no way it came in contact with such a person. It attacks by launching a ball of ice that deals damage and freezes for 1 sec.


Handy Hand

Pushing This hand only appears in stages with obstacles. In those stages, it will push you into obstacles, something you probably don't want to happen. In some stages it will also push you off the map.



Boosting Attack H-H-H seems to be a relative of Graviton. This floating altar machine boosts the attack of nearby enemies. Seems to be related to Shieldon Mk. III and MMMtelite, in one or another way.


Shieldon Mk. III

Boosting Defense Shieldon Mk. III has many shields spinning around itself. It's quite bulky, but it's main attribute is the fact it boosts the defenses of enemies. Quite terrifying if done on a Wall-o-Brick or a Maxihamma.



Boosting Speed MMMtelite's strange energy captors have the magic power of boosting enemy speed. This can make the enemies annoyances to get rid of, especially if they start outspeeding you.


Name Boss of: Description


Lunar Machine V1

Base Sewers A very fast, kinda humanoid machine. Operative must have been obsessed with crescents when creating it, considering it is a very prominent part of it's design. It can curl up into a sphere and roll into players. It can also use it's arms like blades by slashing forwards, or even surprise robots trying to attack him from behind by lifting it's sharp head.



Base Arena A gigantic cube-like machine with 6 legs, 2 on the left and right sides and back side except the top and the bottom. It was built specifically for the arena. It doesn't walks around much, but will rotate itself a lot. It's not named "Knockslice" for no reason, through; it has pincers it can use to clamp on players and can also flick them away. It's also the bulkiest boss.



Martian Desert This thing is buried under the ice in Martian Desert. It's the biggest boss. This collosal mech may punch players around the map and shoot rockets from an arm cannon. Overall, it's the one who does the most damage, as well. It cannot move, but it's massive size and it's arm cannon make up for that. Also the only boss planned to appear in the story.


Evile Penguine

North Pole A very evil penguin robot! It's probably the evillest character in the game. But the reason why he isn't seen as the main villain is that he is absolutely pathetic in fighting. His only attack is tripping on the player, causing it to hit it's own head on the ground and getting damaged. This doesn't works out well considering it's low HP and defense. Oh, and it's pretty slow...Yeah.
Coelachoire Europa Sea Okay, what was in Operative's mind when he made this thing? It's horrifying! This fish-like monster can one-shot players by eating them with it's very scary mouth. It doesn't helps that no music plays when it spawns, and it won't alert you of it's presense until it tries eating you! It also outspeeds some of the slower characters, but gets slowed down by attacks itself.



Machina Asteroida

Asteroid Arena A giant robotic orb that acts like a core, with layers of asteroids protecting it. One has to destroy some of the asteroids orbiting it in order to reveal the core, which is rather vulnerable to damage itself. This core can launch some of the asteroids orbiting it in order to attack players. At low HP, it may even try shooting the robots with lasers in a last effort to defeat them.

Lunar Machine V2

Lunar Base Lunar Machine V1 was crescent shaped, but V2 is much more orb themed. While it is also fast, it attacks with projectiles instead of direct attacks. It is also slightly bulkier than it's first version. It's attacks include charging strong orbs and launching them at foes, spouting a bunch of small orbs in all directions and launching fast crescent-shaped projectiles.


Ruined Residence Moldibrad is a giant robotic worm whose segments are protected with bread. Said bread seems to be very hard since it is unbreakable. It has a knife for a tail. Inside of its two bread "jaws", you can find its actual head, which ressembles a toaster. This head serves as its weak spot, as attacking the bread does barely any damage. It often stays hidden under its arena's floor, but occasionally jumps out to shoot bread out of its head at foes.


One of the most known aspects of Sparkplug are the big changes that happened in it's development.

Work on the game started around January 2015. It started as a Five Nights at Freddy's fangame known as Five Nights at Fierce's. When Poisonshot posted information about the game on a fan-site for imaginary video games, however, it was met with very bad reception due to beign just a clone of the original FNaF with different animatronics. This didn't discourage Poisonshot, however, who found it kind of funny and decided to make a second game. This one was met with much better criticism, as it was very well described and was actually original unlike the first game. Poisonshot also started work on a third game, and two FNaF World-inspired spinoffs. Poisonshot actually planned to make all of these games, but only managed to make a rather buggy prototype version of the first game.

However, Poisonshot began to stop liking the FNaF franchise as much as he did, but still liked the characters he made for the "Nights at Fierce's" series. He had multiple plans to revive the series. One of his ideas was to completely revamp all games. Another idea he had was to make an Undertale-inspired game where there was around 20 "nights" and you eliminated one of the animatronics each night, and depending on which animatronic you fought last, you'd get a different ending and final battle. Another plan was a puzzle-esque game where you could summon robots inspired by the animatronics and make them use their powers to solve various puzzles. He eventually came up with Sparkplug.

At first the game was just a battle game, without a story mode, and a very different story behind it where the robots were just built for various tasks and then modified to battle. However, he didn't like this story and decided to make a new story inspired by the one he made for the "puzzle-esque game". Some characters, such as CeROBral, were also inspired by the designs he made for said game.


Sparkplug was met with rather positive reception. People like the unique take on 3D fighting the game has. Another aspect of the game that is liked a lot are the models, which are much better then the average models made in it's engine. People also like the story and how there are two villains; and the one(s) who is(are) the villain(s) depends on what you think. The diversity of the characters and it's easily accessible gameplay is also very enjoyed by citics. Players also like how the gameplay is deep enough to be played on a serious level, although tournaments are only for fun and don't give out any rewards. Another aspect of Sparkplug that is generally liked is how balanced the characters are; no characters are considered "Broken", although some are considered terrible in serious play.

However, the game is not considered without flaws. Some players have compared the game to Overwatch; both of the games take place in a sci-fi universe and both have gameplay similarities in general. Additionally, a rather large amount of players have called the game "crap" due to it's origins as a FNaF fangame, although most people consider this criticism unfair, saying there is nothing about the games similar to FNaF anymore besides that there are robots, and that the lore is dark like that game.


  • All of the models in the game have been made on ROBLOX. No, seriously.
  • Mr. H20's name should technically be "Mr. H2O". Poisonshot only choose H20 because he though it looked better.
  • Operative is the first character to have been nerfed; his defenses were boosted slightly, but his attacks were weakened in order to not make him outright broken.
  • There are invisible barriers above and around the map. This was mainly added to prevent Navexte from abusing her ability to fly, and also to ensure that no one goes out of bounds.
  • SentROB, Watchword and Zéro are the only characters to have stats that aren't multiples of 5.
  • Isaw-Usaw, Maxihamma, Minihamma, Nozzule, Greeneen, Cry-O-Cryo, Handy Hand, H-H-H, Shieldon MK.III, and MMMtelite weren't made by Poisonshot, but by one of his friends.
    • Knockslice, Evile Penguine and Machina Asteorida's models were also made by him, although their concepts were made by Poisonshot.
