It's an arena-y survival game rather than a Hexen-like, level-based exploratory shooter, but that disappointment aside, Devil Daggers (opens in new tab) looks like a right treat. You're the owner of a magic hand that fires energy at beautifully pixellated hellbeasts, in this upcoming arcade FPS made by one of Hitbox Team (they made Dustforce) and a few others. Here's why I'm excited (via RPS (opens in new tab)):
Devil Daggers is on Steam Greenlight here (opens in new tab), and I wonder how many milliseconds until it gets the go-ahead. It's out later this year, and developer Sorath says it's a "fast-paced shooter that pits you against legions of demons as you struggle to survive as long as you can. Compete for precious seconds with friends or on global leaderboards".
