Super Smash Bros. Y is a Super Smash Bros. game developed by Pyro Enterprizes as a what-if game, imagining if director Pyrostar (t∣b∣c) were director of the Smash Bros. franchise. As such it takes many advancements in gameplay to make it more different from past entries, and will take all games by Pyro Enterprizes as canon as well as Nintendo-developed games.
Y features 2D knockback-based battles similar to the rest of the Super Smash Bros. series, with players utilizing attacks to build up an enemy percentage and knock them off of the screen. The general speed and playstyle is a combination between Melee and Sm4sh, being faster than the latter but slower than the former.
- Adventure Mode- The Enigma Engine: An extended story mode similar to the Subspace Emissary mode from Super Smash Bros. Brawl. The mode is heavily influenced by the Great Maze level from said game, and takes a Metroid-style gameplay as opposed to the prior mode's Kirby-inspired gameplay.
- Classic Mode: Face off against a CPU tournament in this simple ladder-based mode. There are eight levels in the mode: clear one to advance to the next. Clearing Classic Mode grants a trophy of the character used to clear it. The levels follow a simple order:
- LV 1: A normal battle against a character from the player's home series. If multiple people are playing, LV 1 is against a character from the first player's series. Random stage, items on.
- LV 2: A normal battle against two random characters. Random stage, items on.
- LV 3: A battle against a single random character, permanently under the effects of the Mushroom item. Random stage, items on.
- LV B1: Bonus Round 1. Triggers a game of Target Smash with equivalent difficulty to the selected difficulty of Classic Mode. If Classic Mode is being played with two players, Target Tag is played instead. Trigger by clearing LV 1-3 without losing a stock.
- LV 4: A normal battle against three random characters. Random stage, items on low.
- LV 5: A battle against a random boss, fought on the stage in which the boss is found. Items on low.
- LV 6: A battle against a single random character, permanently under the effects of the Metal Box item. Random stage, items on low.
- LV B2: Bonus Round 2. Triggers a game of Platform Rush with equivalent difficulty to the selected difficulty of Classic Mode. Trigger by clearing LV 4-6 without losing a stock; can trigger even if LV B1 has not triggered.
- LV 7: A battle against the player's designated rival character, with slightly above-average difficulty. Uses the rival of the first player if multiple people are playing. Final Destination only, items off.
- LV 8: A 25-man round of Multi-Man Smash. The first 24 opponents are simply Smashsects, but the final opponent is a slightly weaker random opponent. Battlefield only, items off.
- LV 9: A battle against the ultimate boss of Classic Mode, Master Hand. If difficulty is over Normal, then Crazy Hand will appear as well, and if these conditions are met over Difficult, Master Giant will appear as well. Final Destination only, items off.
- LV ???: If the player has cleared all 9 levels within 8 minutes, a secret boss fight against Lady Omega will trigger. Time does not pass in Bonus Rounds, and the loss of a stock will result in a 30-second deduction from this time limit. Defeating Lady Omega grants the player a bounty of rewards, as well as a Lady Omega trophy for the first time the fight is cleared.
- All-Star Mode: Similar to Classic Mode in that it is a ladder-based championship, but All-Star is much more difficult, having the players battle all characters in the game on the same stock, with a limited amount of healing supplies between rounds.
Similarly to Super Smash Bros. for Nintendo 3DS, the rounds progress in chronological order, with the oldest characters being fought first.
(Round List TBA)
Custom moves have been edited for Y. As opposed to three variants on an existing move, each character now has three entirely unique moves for each slot. In addition, stat customization has been enhanced, as there are six stats that can be changed in Y, as opposed to the original 3. These stats are:
- Arms: Controls power and durability of attack items and effectiveness of healing items. Increasing Arms reduces Attack.
- Attack: Controls power of normal and special attacks. Increasing Attack reduces Launch.
- Launch: Controls knockback of normal and special attacks. Increasing Launch reduces Weight.
- Weight: Controls the amount of knockback that the player takes. Increasing Weight reduces Agility.
- Agility: Controls the speed and jump height of the character, as well as the amount of lag on all attacks. Increasing Agility reduces Defense.
- Defense: Controls the amount of damage players take from attacks. Increasing Defense reduces Arms.
Assist Trophies have been removed and replaced with Assist Spheres. While the general effect is the same- summoning a character to fight at a player's side- Assist Spheres are not actual items and objects that must be equipped to a character in customization. Assist Spheres may then be activated once per battle by pressing both the L and R buttons at once (Pyrohedron controller).
In contrast to past Smash games, where certain characters had a counter as a special move, counters in Smash Y are tied to the shield button. Pressing the shield button as soon as an attack hits a character will negate the damage, as well as cause the character to attack the opponent with a forward smash. This maneuver possesses approximately the same timeframe to pull off as a traditional counter and/or a perfect shield, replacing the latter. Characters that formerly possessed counters as special moves have them edited or replaced.
Wraith is a special technique available once a character has reached 200% damage without being KOd. Pressing the secondary shoulder buttons (ZL and ZR on Pyrohedron controller) initiates Wraith, which causes the character to begin emitting blue fire around itself. While Wraith is active, the character deals more damage and knockback, and has drastically enhanced speed. The effect will end after a short period, which gets slightly longer depedning on the player's actual percentage. After it wears off, stats are slightly reduced.
Reaper is a special variant on Wraith that replaces the technique when the player reaches 300% without being KOd. When activated, the character emits more furious purple flames, and has their stats boosted even further. However, Reaper is considered a last resort by the game, and the player will lose a stock as soon as the effect ends. Additionally, respawning after this takes longer than usual, and the character has decreased stats for a short time after respawning.
Bosses work differently than in past Smash games. While SSB4 had bosses as hazards on certain stages, and Quantum utilized the Boss Trophy item, Y has entire stages dedicated to bosses, accurately known as Boss Stages. These bosses cannot be defeated through any means, but if they take enough damage, they will begin working for one of the players, similarly to SSB4's Ridley.
Items are various object that can spawn within the middle of a match, and can be used by players in order to gain an advantage. Item rate can be adjusted to have more or less items appear; however, a new feature to the game is Item Ranking. Items are categorized into three types: Common, Uncommon, and Rare. If items are turned on low, the rarer items will become relatively more common, and if items are turned on high, then they will become relatively less common.
Items can no longer be turned off entirely, though certain specific items (Pokéballs, Assist Trophies, Dragoon pieces, etc.) can be deactivated in Options.
