Crytek have announced Hunt: Horrors of the Gilded Age for PC and undisclosed consoles. The game is a pure 4 player co-op adventure set in the 1800's where players hunt down mythical creatures. The content generation system automatically generates new monsters and maps every time you play so you'll never repeat the same adventure.
They had this to say about the game:
"As the surprises come thick and fast, the terror of knowing that one of the game's grueling boss battles could be just around the corner will keep everyone's pulses pounding, defeating bosses will require close collaboration between hunters as they attempt to figure out and take down some truly terrifying monsters."
