Resident Evil 4 Infinite Ammo Weapons And How To Unlock Them

Mastering the survival horror challenges of Resident Evil 4 requires players to manage limited resources while facing aggressive Ganado hordes. Unlocking bonus weapons with bottomless magazines completely shifts the gameplay dynamics, turning a tense rescue mission into a power fantasy. Securing these elite armaments requires dedication, strategic planning, and completing some of the hardest challenges the game has to offer.
Unlocking the Legendary Chicago Sweeper
The Chicago Sweeper stands out as a devastating submachine gun that can shred through groups of infected villagers effortlessly. To add this classic firearm to your inventory, you must complete the main campaign on Professional mode with an A rank. Achieving this milestone requires finishing the game in under seven hours, demanding a deep understanding of optimal routing and boss strategies.
Once you secure the weapon, you still need to unlock its bottomless capacity by purchasing its special exclusive upgrade from the Merchant. Players can speed up this process by trading Spinels for an Exclusive Upgrade Ticket early in the campaign. Alternatively, spending a large sum of Pesetas on standard weapon upgrades will eventually make the option available.
Acquiring the Devastating Handcannon Magnum
The Handcannon is a monstrous magnum capable of delivering unparalleled damage to even the most resilient boss characters. Veteran players can earn this high-caliber reward by completing a fresh playthrough on Professional mode without utilizing any other bonus weapons. This means you must rely strictly on standard equipment found throughout the village, castle, and island regions.
After proving your martial prowess and finishing this restrictive run, the Handcannon will appear in the extra content shop. Much like other bonus gear, activating its infinite ammo attribute requires a final investment at the Merchant shop. Fully upgrading the firearm unlocks its ultimate potential, ensuring you never run out of magnum rounds again.
Securing the Infinite Rocket Launcher
For players looking to bypass difficult combat encounters entirely, the Infinite Rocket Launcher offers the ultimate destructive solution. Unlike other unlockables tied to specific ranking challenges, this massive weapon becomes available purely through financial accumulation. You can purchase it directly from the Merchant during any New Game Plus playthrough.
The standard price sits at a hefty two million Pesetas, which requires selling off valuable treasures and fully upgraded weapons from previous runs. Equipping specific cosmetic charms can help lower this cost slightly, making it easier to acquire early in your subsequent journey. Once purchased, you can instantly eliminate any target from a safe distance without worrying about ammunition costs.
Maximizing the Infinite Primal Knife
While not a firearm, securing a blade that never breaks is an essential defensive strategy for enduring high-difficulty playthroughs. The Primal Knife is unlocked by tracking down and destroying all sixteen Clockwork Castellans hidden across the game's chapters. These small mechanical collectibles emit a distinct ticking sound, rewarding thorough environmental exploration.
Upgrading this combat knife to its maximum level grants the indestructible perk, allowing you to parry attacks and execute fallen enemies indefinitely. Utilizing a reliable blade saves an immense amount of gunpowder and resources over time. Combining a bottomless firearm arsenal with this durable tool ensures Leon S. Kennedy is fully prepared for any nightmare.
