    About the game

    A prison ship crashes on a strange planet, and the survivors fight their way up through an old underground facility. You open one door at a time. Each door can hide loot or a wave of monsters. You power rooms with a shared pool of Dust and build turrets and other modules that fight for you.

    Up to four of you play online. Each player controls one or more heroes, four heroes in all. You share the Dust, the crystal and the modules, while food, science and industry are split between players each turn. A chat and a trade window help you divide the rest. There is no pause in multiplayer, so you decide fast.

    It suits a group that likes to plan and talk through every move. The PS4 and Switch versions are single-player only.
