GRAV

Grav is a fruit of the labor of BitMonster developer team that belongs to the open-world survival craft combination of genres. There you're able to explore procedurally created planets in outer space. The exploration part includes hunting down yet-to-be-discovered alien species. Since your whereabouts depends on the randomly generated planet you find yourself on at the moment, you have to use skills to survive in an unknown hostile environment. Fortunately, everything you can collect or kill can give you a sort of crafting material. A couple of these materials can be transformed into useful stuff. There are other players with whom you can be friends or otherwise betray them for loot. If you decided to be friendly it is much easier to build a base in Grav using a helping hand.
