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

In order to unlock this weapon, we have summarized the entire roadmap in bullet points for better understanding.
- Players only need the end RE4 Remake in “Professional” difficulty with an A rank in order to complete the Leon “A” Kennedy challenge.
- Once the challenge is completed, the Chicago Sweeper will become available for purchase in the Extra Content Shop for 1,000 CP.
- After purchasing it for the Extra Content Shop, the weapon will appear for sale at the Merchant, and players would need to purchase it.
- The last thing players need to do is to fully upgrade the Chicago Sweeper by either investing 650,000 pesetas or using the exclusive upgrade ticket to unlock the exclusive Chicago Sweeper upgrade.
- Purchase the upgrade for 10,000 pesetas and enjoy unlimited ammo.
Handcannon

- 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, we 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

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

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 we 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.
