: Dedicated players can unlock the Handcannon by achieving a 5-star rank with every character on every stage in The Mercenaries . Once fully upgraded, it grants infinite ammo and devastating power.

For players who want immediate god-like powers without the grind, the PS2 era was defined by external cheat devices like Action Replay Max and Codebreaker . These codes allow for modifications impossible through normal play.

: Advanced patches can enable Walk Through Walls , "One-Hit Kills" for enemies, and even Bullet Time effects that slow down the action.

: The most sought-after "cheats" are the Infinite Rocket Launcher (available for 1,000,000 Pesetas in New Game Plus) and the Chicago Typewriter , a Thompson submachine gun with bottomless ammo unlocked by beating the Separate Ways campaign.
