I haven't got this game (waiting for the release for this one, have more than enough EA games in my list) but my partner has it and I've watched him play it bit. It seems similar to Planet Explorers - though different look / feel and simpler crafting/creation. You are basically sent to a different world to colonise it - so you gather, kill and build your base. It will be awhile till it comes out though.http://store.steampowered.com/app/259570
There isn't much to do at this stage but looks like they have quite a bit planned. You can defend it with turrets, missile launchers etc - who doesn't love turrets?
