Infernox armour is the best armour in Ratchet & Clank: Up Your Ass that contains Carbonox Armour. It only absorbs 85 percent damage and is far too cheap for its power; so people say it is crappy and that Carbonox Armour is better. It was so crappy that the company that made it ran out of business for a good reason. The Obliterator busts it so easy. Don't buy it, it is a waste of cash except that IG made a skill point for getting it so that people would actually buy it.
