GRP Battery Pack
Game: The Callisto Protocol
Instantly recharges the GRP power meter. Due to the energy required, all battery packs can only be used once.
Item Type: Ammo
Sell Price: 10
Used for: GRP (Gravity Restraint Projector)
GRP meter recharges over time, but GRP Battery Packs can instantly refill it on use. This can come useful when the natural refill struggles to catch up with how often you use up the energy, especially after you have upgraded your inventory.
