Repair Shield is a MOD in Metroid Prime: Federation Force. Only one copy of it can be equipped at a time. When used, the healing properties of a Repair Capsule are increased, as deployed Capsules will repair allied Mechs that are within it. This is somewhat similar to a Safe Zone in Metroid Prime 2: Echoes. "Deploys a shield that will shortly repair any allied Mech inside of it."
