A conditioned infantry unit lands on an abandoned industrial moon to reach a subsurface signal-core and plant a field-dampening warhead.

The interference does not just distort the battlefield; it drags the soldiers’ training facility back into their minds until the core and the cage become the same place.

Reality filters begin to fail, making depth, gravity, terrain, and even squad members unreliable.

The unit loses men to falls, friendly fire, disappearances, and a grenade detonation as command contact vanishes behind the signal.
