A Repair Capsule is a Support item in Metroid Prime: Federation Force. Replacing the Energy Tanks of traditional Metroid games, it is a healing item in the field. Equipped prior to the start of a mission, the capsule can be fired at the ground and walked into to heal Federation Force members, or shot at a fellow Marine to replenish depleted health. If a teammate is defeated, they can be revived with half of their health. 50 points are rewarded to the Marine's score for healing a friend. Repair Capsules can also be used on mission-critical objects, such as the Data Uplink and Cargo Tram.
Repair Capsules appear differently in Blast Ball. Two appear at a time, color-coded by team, on each end of the G.F.S. Aegis, and can be used by any contestant on that team. A player from one team cannot use a capsule from the opposing team, however (i.e. someone on team Indigo cannot use a capsule from team Gold). The capsules reappear every few minutes.
