Hellraid is a first-person fantasy action game; the developers described it as a cooperative first-person slasher game, which would include gameplay elements borrowed from modern first-person shooters and tabletop role-playing games. The game will have a single-player campaign and a four-player mode. The player will fight the undead and demons that have taken over the surrounding lands.
In 2013, it was planned to introduce 4 classes of heroes into the game: warrior, paladin, mage and thief, each with their own set of talents and skill with weapons. Later, the developers decided to abandon the division of characters into classes in favor of one universal one, combining different skills. Artificial intelligence called Game Master must adjust the game to the players, adjusting the difficulty of the game, the number and location of enemies and chests with valuable things, generating missions depending on the level and composition of the players' team.
