I have to admit I'm a little scared of Sulfur. I'm a fan of classic FPS games like Doom, ARPGs like Diablo, and roguelikes like Shattered Pixel Dungeon. So a game that combines aspects of all three types of game into one seems dangerous to me. It feels that if I dare play it I'll become lost, forever sucked into its world. That threat is now very real, as Sulfur is out now in Steam Early Access and ready to be played.
