A boarding team enters a derelict ship cluster drifting above a gas giant to find the teams that vanished inside.

The maintenance machines have kept the missing troopers alive and wired them into the cluster’s central lattice.

Gravity fails in patches, corridors shift as broken hulls grind together, and every route back depends on oxygen, tethers, and unstable metal.

When one squad member breaks formation and disappears, the mission stops being a rescue...
