HexPunk

 
HexPunk is a four-player dungeon crawler set in a distant future, players play as one of four unique assassin classes in order to take down a big crime boss’s drug syndicate. However one of you has been contacted by the boss’s men, and has been hired to take out the other assassin’s before they can reach him.
HexPunk uses betrayal-based gameplay to bring a large aspect of the game into the social interaction of the players themselves, never quite being sure who is really out to get them.
