If there's one thing I am a little too obsessed with, it's rhythm games. One of my favorite PC games ever made is Metal Hellsinger, and before that I spent far too much time on Riot Forge's Hextech Mayhem. This Steam Next Fest, though, my attention has turned to Beat Slayer, a new indie that channels the gritty, gloomy dystopian setting of Fallout and the on-beat combat and comic book style of HiFi Rush. If two of the best Bethesda games had a baby, it'd be this game.
