Eternal Pokémon: Sanity's Requiem (Japanese: ポケットモンスターナイトメア：永遠の闇 Pocket Monsters Nightmare: Eternal Darkness) is an M-rated horror game created for Game + Pokémon for the Nintendo Chrome. It is a spin-off of the Pokémon series based upon the Nintendo GameCube horror-survival game Eternal Darkness, keeping the multiple storylines of Eternal Darkness, while still retaining the capturing and battling aspect of Pokémon. Like Pokémon, there are eight gym leaders, though are not known as such, and are considered "bosses" for their time period.
The gameplay is a horror game with puzzle and fighting elements, in vein with both the game's prequel - Eternal Darkness: Sanity's Requiem - and the popular GameCube title Luigi's Mansion. Players explore the overworld, completing various puzzles - such as finding keys or manipulating objects - before the story progresses.
Throughout the game, the player is able to examine various objects, to understand more about the past, and what may happen in the future.
Players fight enemies using various weapons they can find through the game. While attempting to keep their health bar (a "potion" bottle, based off the Generation IV sprites of the same item, filled with a red liquid that empties upon taking damage). Upon the health running out, players will experience a "sanity effect", where the player's character essentially dies, before the Shadow Omnibus revives them (back at the last save).
In lieu of the Pokémon franchise, the player is also able to capture the spirits of those that they fight within the Shadow Omnibus, to use against other spirits. It is possible to save 6 spirits to a single page, with 35 pages being able to store spirits. In battles, the player is unable to switch pages, as the page acts as the player's party.
Similar to the Pokémon franchise, only certain varieties of spirits reside only in certain time periods, meaning the player will be unable to capture them should they progress past that certain time period (unless, of course, should they return to the period for story reasons).

The Boss Characters are the equivalent to Pokémon's Gym Leaders that one must challenge in order to gain access to the Elite Four. The Boss Characters take command of up to five different types of enemies, which the player must usually face in groups of three, before they must fight the Boss itself. Defeating the Boss rewards the player character with a Spatial Seal, that automatically gets placed within the Shadow Omnibus. The Boss Characters also serve as the final bosses for the time period, often showing a cutscene before travelling back to the present era.

Runes are mysterious objects that are both emitted - and collected - by the Shadow Omnibus. The Runes are often found around the world, with more common ones being usually out in the open, while more powerful ones are hidden away and are usually captured upon completing puzzles. When used, Runes drain power from the person who uses the Shadow Omnibus, but restores an equal amount on the Sanity Meter. Up to six Runes can be present in one chapter, and the chapters - and therefore the entire line-up - must be changed in the menu in order to get the team of six Runes that one most desires.
