Recuperation

Recuperation is the Rook Runner Shell's Prime ability in Marathon. It provides the Rook with a self-healing restoration effect, recovering a portion of health over time or in a burst when activated. For a Runner Shell that lacks offensive combat abilities and operates primarily in solo or low-profile scenarios, Recuperation is the core survival mechanic that allows Rook to sustain through environmental damage, minor skirmishes, or the wear of extended looting runs without relying on consumables or a Triage squadmate.

Recuperation is most valuable in the middle and late stages of a run, when the Rook may have taken incidental damage during resource gathering and needs to restore health before extracting. Because Rook does not have a combat-oriented kit, staying healthy through self-repair rather than enemy engagement is the preferred survival strategy. Timing Recuperation after disengaging from any threat, rather than while still under fire, maximizes the healing benefit and keeps the Rook viable for continued looting. In the context of Rook's full kit alongside Signal Mask, Recuperation completes a two-ability survival package: avoid detection, and if damage is taken, recover efficiently and continue the run.
