Completing Resident Evil 4 Remake on Professional difficulty with an S+ rank is no small feat, yet it’s the only way to unlock Leon’s signature cat ears—a cosmetic accessory that grants unlimited ammunition. While the challenge may seem daunting at first glance, players can significantly reduce the time required by leveraging specific items earned through other playthroughs.

The cat ears are unlocked after purchasing them from the Extra Content Shop in the main menu for 2,000 Completion Points (CP). To qualify for this reward, a player must finish the game under strict conditions: playtime must not exceed five hours and thirty minutes, the save file must be fresh (not a New Game+), and no more than fifteen saves can be used throughout the run.

Strategies to Simplify the Challenge

The primary obstacle is time management. Professional difficulty is punishing enough on its own, but the need for speed adds another layer of complexity. However, certain items—such as the Chicken Hat, Chicago Sweeper, and Handcannon—can drastically improve efficiency during a run.

Unlocking Leon’s Cat Ears in Resident Evil 4 Remake: A Guide to Unlimited Ammo
  • Mercenaries Mode: Completing all three stages with at least an S-Rank grants the Handcannon, one of the most useful weapons for a Professional playthrough due to its high damage output.
  • New Game+ Playthroughs: A Professional run in New Game+ mode allows players to use the infinite Rocket Launcher, making it easier to secure the Chicago Sweeper without extending the main game’s duration.

Players are advised to prioritize earning the Handcannon first, as it provides substantial firepower and is the quickest way to prepare for a successful S+ run. Additionally, disabling autosave and avoiding the 'Continue' option after death can save significant time by preventing unnecessary playthrough extensions.

Finalizing the Cosmetic

Once the cat ears are purchased, they can be equipped in the Extras menu under Leon’s accessories. The cosmetic not only serves as a playful nod to the game’s fandom but also offers practical benefits, such as unlimited ammunition, making it a coveted reward for those willing to tackle the challenge.
