Been holding off on this game until they released multiplayer, turns out multiplayer was added last week.
So far its been fun, the game is still a long way away from being a proper game but it offers something no other game does:
Build huge ships and smash them into things.
This game is a Space Lego Simulator or Minecraft in space.
There is no dedicated server yet or even plans for a linux server so hosting one might be difficult but multiplayer itself seems to work really well. You can just open your game up to the public ( not recommended ) or your steam friends.
While I have sworn off early access on steam, this game I made a exception too. Its just way too cool not to get and muck around with. You can grab it from steam
