GRAV is a upcoming title from Bitmonsters, which takes elements such as Harvesting, FPS combat, crafting (weapons/armors), adds some PVP elements and even base building and combines them all in a sandbox environment!
Oh and there's even dance offs, in space.
Currently the title is being developed on the Unreal Engine for the PC platform and has been in development for 5 months so far and is currently up on Steam Greenlight for voting.
Definitely worth checking it out! Especially if you're a fan of any of those elements mentioned above. And for those not in the know, Bitmonster is made up of several former Epic Games members that worked on titles such as the Unreal Tournament series and Gears of War!
