- 1–4 players
- Online & local
- Two-player co-op
Game modes
Versus
1–4 playersEveryone builds their own tower. Against friends or bots.
Planet Rescue
Build a tower, get your Stackonauts to the ship, and shell the ones your rivals built.
Station Rescue
Race the clock: the area is contaminated and Stackonauts waiting outside are dying. Build up to the stations before it is too late.
Pit Rescue
Cram as many blocks onto the pillars as you can before the space runs out. No cannons.
Orbit Rescue
Fly the shaft, dodge the obstacles, and pick up Stackonauts. No building.
Blackout Rescue
You only see around your ship. Search for Stackonauts, then dock with the mother ship in time.
Expedition
Co-op · 2 playersOne build for two, together against the computer.
Babylon Tower
Two players against the computer: one builds, the other defends and picks the pieces. Get your Stackonauts as high as you can.
Bridge to the Unknown
Two players across the chasm: build a bridge from pier to pier and walk your Stackonauts over it. More of them wait on the piers to be rescued on the way.
