Beat Hazard Ultra is an awesome Steam game turned iOS title that has found a way to eat at my time even when I’m not at my computer. Published by Cold Beam Games, it’s a “twin stick shooter” without the sticks. Beat Hazard Ultra features procedurally-generated levels based on your own music. I loved the Steam version but was doubtful about the iOS version. However, I was proven wrong when I tried it and was amazed!
