Planet Nomads looks pretty cool—its announcement trailer shows a sci-fi sandbox game with lots of building, exploration, and some combat elements.
It’s a little passé to call something “Minecraft-like” at this point, but there do seem to be some similarities. The character can harvest rocks and metal (and possibly other resources) in order to build a settlement; there are alien lifeforms that may be hostile. Players can pick up a gun and try to defend themselves from a charging rhinoceros-type creature at one point.
Check out the trailer for yourself and see if you agree:
