Upping your Arsenal is a silver trophy awarded in Ratchet & Clank: All 4 One. It is obtained when the half of all the weapons are bought for one character.
This trophy will be obtained naturally, especially if going for the For the Zombie Apocalypse trophy. Only the playing character's special weapons count towards the amount of purchases needed.
