SPRAWL zero, the prequel to the recent SPRAWL, has a demo out now. I will say, it doesn't hit quite as good as the first game, but it's still a pretty good FPS. The grav manipulation mechanics are a more refined version of what the grav gun gave in HL2, and there are some new abilities (like a grav shield that grabs bullets and builds up force to throw them back at enemies) that can turn the tide when you're surrounded/outgunned.
Soundtrack is about as good as the first game so far, and I enjoyed some of the weapons on offer, even if some of them are bog standard (pistol, rifle, smg, etc). Depending on how much they ask for it on release, I think I'd definitely get it.
