You are stranded in an asteroid, and you need food, oxygen, stamina in order to survive in this Space-Building Game. You have to cooperate with other players in gathering various resources (ores,fuel,water,oxygen,power). Alternatively, you can also hire bots/slaves to do tasks for you (cleaning dirty floors, butchering corpses, farming, harvesting, turret ammo refill). Additionally, the enemy will send raids every 3 days so you have to ensure that proper defenses are setup in order to survive.

Can you survive in Space?
