A tunnel militia unit enters a reactivated refinery beneath a dead mining moon, searching for coolant to keep their shelters alive.

Inside, they discover the enemy is using human minds as control substrates—and one of them is already part of the system.

Cut off from extraction and hunted through machine-controlled tunnels, the unit is forced upward into a collapsing refinery spine while the mission fractures between survival and something more personal. What begins as a resource run becomes a confrontation with an occupation that does not just kill—but repurposes.
