Explore hostile alien planets in full 3D as a lone astronaut. Alien lifeforms fight back if you try to scan them at full strength, so blast them with your blaster until they're weakened, then scan them before they recover. Watch your oxygen, grab air tanks, dodge vents and meteors, and patch suit holes before you leak out. Scan every lifeform and launch your rocket. Then survive the trip aboard your ship: blast aliens that sneak in, weld hull breaches from asteroid hits, keep the generator powered, oxygen high and fuel topped up, dump trash out the airlock, and watch the progress bar until you reach the next, harder planet. The ship is now a maze of rooms and doorways, decorated with plants, crates, pipes and a holo table, and you can spend credits in the Robot Bay to hire crew robots that recharge, refuel, recycle air, haul trash, weld breaches and blast intruders. Spend credits on stronger blasters and suit upgrades at the base pad shop or between planets.
