A psychotic A.I. rebuilding itself
You play RSR-648b, a psychotic warship A.I. that wakes up from a long hibernation somewhere in space. It needs to rebuild itself and recycle anything it finds to make it back to central command. In its madness, every unidentified moving object becomes a threat that has to be crushed. The goal is to shoot and loot your way through alien territory and back to Earth.
Building and fighting through sectors
The loop is simple: build your spaceship from scratch, load it with weapons, then destroy waves of aliens across horizontal scrolling levels. Loot the carcasses of what you kill, extend your ship with the parts you pick up, and jump to the next sector for more action. There are many pieces of equipment and weapons designed to interact and combo with each other, so the ship you build keeps changing as you go. Levels are procedurally generated, and the game mixes space shooter action with roguelite progression.
Playing together on one ship
Local co-op supports up to 4 players sharing the same starship. Steam also lists Remote Play Together, so friends who are not in the same room can join in. The co-op is described as crazy and unique, with everyone working on one ship rather than flying separate ones.
