Skein is an old-school-style dungeon shooter currently in development. Taking a leaf from the Gauntlet school of games, Skein is a fast paced one or two player (co-op) game where you battle through hordes of monsters on a quest to save the soul of a talking sheep. The game features hundreds of enemies, a huge number of spells, 6 different playable characters and procedural dungeons with secret rooms, traps and all!
This guy is a little bastard to fight against... When invisible he can't be shot, and he uses this to attack you with different magic before running away again!
