Double Damage is a power-up found in the Metroid Prime Hunters Multiplayer and Survival Mode in Metroid Prime Hunters First Hunt. It is not found in arenas. Like its namesake, the Double Damage doubles the usual damage done by an attack. It works with any hunter, and its appearance resembles that of a radiation symbol, except shaded brown-orange and black. The power-up renders a hunter purple in colour. It is found in arenas like Processor Core, Ice Hive and Compression Chamber.
In Metroid Prime Hunters First Hunt, in Survival Mode, it is found in the Assault Cradle level on the third floor. It shares the same use as Massive Damage from Metroid Prime 2: Echoes's multiplayer mode.
