RE4 Remake Infinite Ammo How to Unlock Unlimited Ammunition

Surviving the horror encounters of the Resident Evil 4 Remake often tests your resource management and marksmanship to their absolute limits. Unlocking infinite ammunition completely transforms the gameplay, allowing players to unleash relentless firepower without worrying about empty magazines. Acquiring these special perks requires dedicated effort, playthrough strategy, and completing specific late-game achievements.
Unlocking the Cat Ears Accessory for Universal Infinite Ammo
The most comprehensive way to grant every firearm infinite ammo is by obtaining the Cat Ears accessory. To unlock this coveted item, players must complete the main story on Professional difficulty with an S+ rank. Achieving an S+ rank requires completing a fresh New Game run in under five and a half hours while using no more than fifteen manual saves.
Once equipped on Leon, the Cat Ears grant infinite reserve ammunition for almost every weapon in your inventory without needing to reload endlessly from picked-up boxes. However, the RPG remains an exception as it utilizes its own specialized variant. Equipping this accessory makes subsequent high-difficulty runs considerably more manageable.
Earning Exclusive Infinite Weapons
Beyond accessories, specific iconic weapons feature built-in infinite ammunition options that can be purchased or upgraded. The Infinite Rocket Launcher becomes available in New Game Plus at the Merchant for two million Pesetas. Acquiring the Charm that discounts rocket launchers can significantly reduce this steep financial requirement.
Additionally, weapons like the Chicago Sweeper submachine gun and the Handcannon revolver can attain unlimited ammo through their Exclusive Upgrades. Players can either fully upgrade all base stats at the Merchant or purchase an Exclusive Upgrade Ticket using Spinels earned from Merchant requests. Applying the ticket immediately unlocks infinite ammo for that specific weapon regardless of its standard upgrade levels.
Strategies for Speedrunning Professional Difficulty
Securing the S+ rank on Professional mode requires meticulous planning and familiarity with optimal routes through every chapter. Utilizing bonus weapons unlocked from prior runs, such as the Primal Knife or Chicago Sweeper, can drastically ease combat encounters without invalidating the S+ rank requirements. Managing your limited manual saves for high-risk sections like the Water Room or late-game boss fights is equally crucial.
By prioritizing speed, avoiding unnecessary side combat, and efficiently leveraging Merchant trades, earning infinite ammunition becomes an achievable milestone. Unlocking these game-changing features provides immense replay value, letting you experience Leon's survival mission with total offensive freedom.
