Armor served as a collectible type of equipment that was used to increase damage reduction. Ratchet could purchase armor sets from Gadgetron's armor vendor by spending bolts, unlocking new sets upon progressing through the story. Each armor had its own distinct color style, and each superior version would add more armor panels, culminating in the Infernox armor, which even fully covered Ratchet's head, ears, and tail.
Purchasing the Infernox armor unlocks the skill point "Turn up the heat". The Infernox armor also becomes temporarily available during inferno mode, activated through breaking inferno crates, which grant temporary invincibility and a pair of flaming wrenches that kill anything in one hit.
