Armor was a new type of collectible equipment, designed by Endako fashion experts, first featured in Going Commando. Ratchet could purchase armor sets from Megacorp armor vendors by spending bolts, upon progressing through the story and discovering new vendors. Each vendor was respectively found on the planets Dobbo, Boldan, Snivelak and Grelbin. In challenge mode, one was placed on Oozla as to avoid limiting the player to any armor until reaching Dobbo. Each armor had its own distinct color style, and each superior version would add more armor panels, culminating in the Carbonox armor, which even fully covered Ratchet's head, ears, and tail.
Ratchet started with the Commando-Matic body armor, also called the Commando suit, for free, as it was standard issue for all Megacorp commandos. This armor, like all the others, contained a built-in O2 Mask. They also absorbed nanomites dropped by defeated enemies and used them to upgrade Ratchet's maximum nanotech and his weapons.
