Set in a "vast, mystical purgatory" called the Downside, Pyre is a party-based RPG focusing on an ensemble cast of characters engaged in 3-on-3 battles called Rites.
The core of the game is a single-player campaign featuring a branching story designed to eliminate any game over fail states. Without giving a specific length, Supergiant have said that the campaign is longer than either Bastion or Transistor.
Versus Mode is a local competitive multiplayer game type for two players, or one player and the CPU. It is conceived of as a "bonus" to the single player campaign, and will not support online play.
