Weapons mods were modifications that Ratchet could buy and add to his weapons to improve their power or to give them an extra ability. Mods first appeared in Going Commando, as sold by Slim Cognito at the back of his truck on various planets in the game.
Ratchet & Clank: Going Commando
In Ratchet & Clank: Going Commando there were three types of mods: the lock-on mod, the shock mod and the acid mod. Lock-on could be added to any weapon that Ratchet owned, but shock and acid mods could only be attached to specific weapons. Slim Cognito sold these mods at the back of his truck on various planets.
Ratchet & Clank: Up Your Arsenal
In Ratchet & Clank: Up Your Arsenal, weapon modifications were automatically added on as Ratchet used and upgraded his weapons.
In Ratchet: Deadlocked, mods took the center stage as the main source of weapon improvement. There were two classifications of mods: alpha and omega. Alpha mods improved a weapon basic stats and include speed, knock-back, damage, range, ammo, blast-range, jackpot, and nano-boost. Multiple alpha mods could be equipped with more modification slots opening up once weapons were upgraded. Omega mods included shock, brainwash, napalm, freeze, morph, infect, time-bomb, and mini-bomb. Only one omega mod could be an equipped at a time per weapon.
