Cyborg Rage, a shmup with procedural enemy generation similar to how Left 4 Dead does it, is now available on Steam. After its beta last November, the game cleared Steam Greenlight and is now available for full purchase.
There are some co-op concepts I can get behind. Like the horde/director mechanics behind games like Left 4 Dead and Warhammer 40k: End Times - Vermintide. Developer Ragiva Games is taking those concepts and applying them to their side-scrolling arcade shooter, Cyborg Rage. If you're interested in checking out what that looks like, then you'll get your chance this weekend.
