About this item:
Project Asteroids - Online Survival PVP oriented game
I have no feelings. I have no fear. I must work. And I’m working. My modules are outdated, but as long as they are, I’m useful. My body is rusted, but as long as I can move, I’m useful. I don’t know where I am, but it doesn't matter. I know aim.
To survive.
Being on an asteroid in one of hundreds of thousands of newly built star systems, use everything that will help you survive.
Explore every bit of this strange universe. Get resources, exchange them or make purchases in shops at stations.
Build bases in open space. Equip them and unlock new crafting recipes. Upgrade or replace base modules and devices.
Team up with friends or fight other players for rare resources, for a place under the light of a dying star.
