Here’s How To Unlock Infinite Ammo In Resident Evil 4

It's easily the hardest unlockable in the game.

Resident Evil 4 is excellent in many ways, but it does a great job of honouring many Resident Evil traditions too. Sure, you can unlock the Infinite Rocket Launcher after finishing the game and shelling out an eye-watering TWO MILLION pesetas, but what if you could bring all of your awesome weapons into the fold, but with infinite ammo? The solution is here, but it’s not easy.

So many Resident Evil games allow you to earn Infinite Ammo for your weapons long after finishing, though sometimes a few only opt to give you an infinite rocket launcher. After all, what more could you need? The options are so much more numerous in Resident Evil 4.



When you first boot Resident Evil 4, the game will cheekily let you know in the challenges menu that the Cats Ears are unlocked by completing Professional mode with an S+ rating.

This is easily the hardest feat to achieve in the game – it requires you to finish the game on a fresh playthrough, without carrying over new game plus upgraded weapons, in under five and a half hours and ONLY saving fifteen times.

This is undoubtedly one of the most demanding challenges I’ve faced in a Resident Evil game, maybe even ever. Professional mode doesn’t have autosaves, and the chapters can be long, and there are sixteen of them.

But completing the challenging mode will award Leon with the cat ears. These, when worn, means that Leon can reload his weapons from an infinite pool of ammo. So while you’ll still have to reload your weaponry during the more intense fire fights, you’ll never run out of ammo as long as you wear your cats ears. However, this doesn’t count for the rocket launcher, so if you want an infinitely firing rocket launcher, you’ll still have to shell out the two million as previously stated.

There are other accessories too, which I’ve detailed in a comprehensive guide to the costumes Leon and Ashley can wear elsewhere, but these are easily the most useful of the lot.

Of course, if you can’t be bothered doing this, you can easily unlock infinite ammo for two of the game’s secret weapons by fully upgrading them. I’ve detailed those in a guide for you too.

Resident Evil 4 is now available for PS5, PS4, Xbox Series X|S and PC. Amazon has the cheapest price at $84.99 with free shipping.

We gave the game an incredible 10/10 in our review, saying “Resident Evil 4 translates a game already revered into an absolute masterpiece. The tension is heightened and the combat is stronger than ever, all while still maintaining the corny dialogue and humour that the original game was known for. While there are a few minor aspects missing, Resident Evil 4 is a strong example of what any remake should be and is well worth your time.”
