Blackwater is actually a fan mod of Ashes. It remixes levels and weapons, as well as tuning for difficulty. Haven’t tried it yet, but it does look fun. The third/end of Ashes is Death Zone. But there is a lot of stuff being made by a lot of talented devs in the Ashes scene. It’s pretty neat.

The sequel (Ashes: Afterglow) is even better. I’m not saying 2063 is bad or anything, far from it, but the sequel is just showing how much they learned on the original. Both are worth your time, and the third is in dev currently.
