Pilot your ship across a procedurally generated star map as corruption spreads inward. Each sector holds a stabiliser; protect it from raiders and pump energy into its shields. Jump between nodes, prioritise threats, and manage energy. Hold the line until time runs out, or be consumed by corruption.
