The trend has not changed with the release of Resident Evil 4 Remake, as the game features a ton of infinite ammo weapons to unlock, which also encourages replayability. In order to make Leon a force to be reckoned with, one must know how to unlock every unlimited ammo weapon in Resident Evil 4 Remake.

How To Unlock Unlimited Ammo

The method for unlocking unlimited ammo for each weapon is quite different from one another, but the one thing they all have in common is that players need to end RE4 Remake at least once and unlock the Professional difficulty.

Once you have ended Resident Evil 4 Remake, you’ll need to follow the methods listed below in order to unlock your preferred unlimited ammo weapon in Resident Evil 4 Remake.

Chicago Sweeper

The legendary weapon from the original Resident Evil 4 makes a return in the remake. While it is not as good at destroying hordes of enemies in the remake as compared to the original, it is still a weapon worth investing in.

In order to unlock this weapon, I have summarized the entire roadmap in bullet points for better understanding. 

  • Complete RE4 Remake in “Professional” difficulty with A rank for Leon “A” Kennedy challenge.
  • Available for purchase in Extra Content Shop for 1,000 CP.
  • Purchase at Merchant after buying from Extra Content Shop.
  • Invest 650,000 pesetas or use exclusive upgrade ticket to fully upgrade.
  • Purchase upgrade for 10,000 pesetas for unlimited ammo

The Handcannon is relatively easier to unlock compared to the Chicago Sweeper as it does not require the player to end in Professional difficulty on a specific rank. Rather, it is available for purchase quite instantaneously after ending on the Professional difficulty once(without any special weapons). Here is the rest of the roadmap summarized in points.

  • Once players have ended the Professional difficulty, then they will first need to purchase the Weapon from the Extra Content Shop for 1,000 CP. 
  • Now you can go and purchase the Handcannon from the Merchant.
  • After purchasing the weapon, players will need to fully upgrade the Handcannon by either spending 540,000 pesetas or using the exclusive upgrade ticket.

Obtaining 540,000 pesetas is honestly not so hard if you take the time to collect the treasures RE4 Remake has to offer, and you can very easily obtain enough pesetas before even reaching the Salazar boss fight.  Also, purchasing its exclusive upgrade is much cheaper than purchasing the Chicago Sweepers exclusive upgrade.

Speaking of which, I will recommend unlocking the infinite ammo for this weapon before taking the plunge and challenging yourself to unlock the Chicago Sweeper. With endless ammo, the Handcannon is bound to make the challenge much easier for you.

Primal Knife

While the Primal knife is not exactly an unlimited ammo weapon, it does follow the principle of providing unlimited benefits, thus earning it a spot on this list. In order to unlock this weapon, players only need to complete the Revolution Wind-Up Challenge, which requires the players to destroy all 16 Clockwork Castellans.

Unlocking this weapon should be your first priority because the knife with unlimited durability will ultimately become your best friend in future playthroughs, especially in the Professional difficulty, because you wouldn’t have to worry about your knife breaking all the time.

However, do keep in mind that you will have to fully upgrade the Knife first in order to make it indestructible.

Rocket Launcher

The Infinite Ammo Rocket Launcher is one of the easiest special weapons to unlock in Resident Evil 4 Remake, solely due to the fact that you are not required to finish any challenge. The Rocket Launcher will be available to purchase from the Merchant for 2 million pesetas after you have ended once and started New Game Plus.

Cat Ears

And finally, if you wish to obtain the silliest accessories, then you’ll need to complete the hardest challenge in RE4 Remake. Cat Ears don’t come cheap. That’s something one will be able to say with certainty after this challenge. In order to unlock Cat Ears 

  • Players will need to end RE4 Remake in Professional Difficulty with an S+ Rank.
  • The Cat Ears will be available for purchase in the Extra Content Shop for 2000 CP.

You may be asking why you need Cat Ears and what is its relevance with this unlimited ammo in Resident Evil 4 Remake article.

Once equipped, Cat Ears will unlock unlimited ammo for every normal weapon in the game (excluding the Rocket Launcher). So, if you wish to demolish hordes of enemies with your favorite handgun or shotgun in Resident Evil 4 Remake, then obtaining the Cat Ears accessory is the way to go.

My Personal Thoughts On Unlimited Ammo

In my opinion and 30-hour experience, unlocking unlimited ammo in Resident Evil 4 Remake is a game-changer that adds a layer of excitement and strategy to the gameplay. It rewards players for mastering the game on the challenging Professional difficulty and provides options for each player’s preferred playstyle. The return of classic weapons like the Chicago Sweeper and Handcannon, coupled with the ability to upgrade them for unlimited ammo, gave me enough firepower to tackle hordes of enemies with confidence.

The inclusion of special items like the Primal Knife and Cat Ears accessory added even more variety to my arsenal. The Primal Knife, while not providing unlimited ammo, offers durability, which can be a lifesaver in the unforgiving Professional mode. Cat Ears, on the other hand, provide a unique twist by granting unlimited ammo for normal weapons when equipped, letting players mow down foes with their favorites.
