How to Get Infinite Ammo in Resident Evil 4 Remake

You get infinite ammo in Resident Evil 4 Remake in four ways: give the Handcannon or Chicago Sweeper its exclusive upgrade, buy the Infinite Rocket Launcher in New Game Plus, or wear the Cat Ears accessory after an S+ clear on Professional. None of them comes from simply playing the story once; each sits behind The Mercenaries or a post game condition, so the real question is which unlock chain costs you the least time. For most players that is the Mercenaries route to the Handcannon, followed by one Exclusive Upgrade Ticket.

For this guide we checked Game8's infinite ammo, bonus weapon and exclusive upgrade pages, PowerPyx's trophy roadmap and the Steam add-on list for Resident Evil 4 in November 2026.

The Four Routes at a Glance

Every infinite ammo option sits behind a post game condition. Here is what each one asks of you and what it gives back, using Game8's unlock data and costs.

Infinite ammo sources in RE4 Remake (Game8 and PowerPyx, November 2026)

Source	How it unlocks	Cost	Usable on a fresh New Game?
Handcannon (magnum)	S rank on all 3 Mercenaries stages, or a Professional New Game clear with no bonus weapons	1,000 CP, then exclusive upgrade	Yes
Chicago Sweeper (SMG)	Professional clear with an A rank	1,000 CP, then exclusive upgrade	Yes
Infinite Rocket Launcher	Sold by the Merchant in New Game Plus	2,000,000 ptas	No, New Game Plus only
Cat Ears (accessory)	Professional clear with an S+ rank	3,000 CP	Yes

Two details trip people up. First, the Handcannon and Chicago Sweeper do not come with unlimited ammo out of the box. Their exclusive upgrade grants it, and that upgrade only costs 10,000 pesetas once every regular tier is bought, or one Exclusive Upgrade Ticket if you skip the tiers. Second, the Primal Knife often gets lumped in here, but its exclusive upgrade makes it indestructible rather than giving you bullets.

The Fastest Route: Mercenaries to the Handcannon

PowerPyx recommends starting here even before your first story run, and it is good advice. The Mercenaries is a free add-on that launched on 7 April 2023 and has to be downloaded separately from your platform's store before it appears on the title screen. Score an S rank on each of its three maps, and one character is enough, to unlock the Handcannon in the Extra Content Shop.

PowerPyx's tips for the S rank are simple: chain kills quickly to keep your combo running, grab the green time bubbles and yellow Mayhem bubbles, and shoot enemies in the legs to set up kicks that also hit anyone nearby. A combo in the region of 100 kills usually carries enough points. You do not need S+ or S++.

Next, collect the Completion Points. You earn CP from finishing story chapters and completing challenges, so the 1,000 CP for the Handcannon arrives naturally during a first playthrough. Buy it under Bonuses, then Extra Content Shop, then Weapons, and pick it up from any typewriter's storage.

The final step is the ticket. The Merchant adds the Exclusive Upgrade Ticket to his trade stock in Chapter 7 for 30 Spinels. PowerPyx counts 31 Spinels available from the Village section if you finish every Merchant request there, so a player who clears the blue notes can upgrade the Handcannon the moment they reach the Castle. Our Exclusive Upgrade Ticket guide covers the second ticket, which costs 40 Spinels from Chapter 13.

Chicago Sweeper: Professional A Rank in Under Seven Hours

The Chicago Sweeper unlocks when you finish Professional with an A rank, which on that difficulty means a final time under 7 hours. Professional itself unlocks after your first clear on any difficulty.

The key point is that an A rank, unlike S+, can be earned in New Game Plus. Push Square and Gamer Guides both note this, and PowerPyx's roadmap leans on it: load a cleared save, choose Professional, and carry your upgraded arsenal with you. Professional has no autosaves and only allows perfect parries, so the extra gear matters.

Time is the only thing that counts toward the rank, and deaths add to it. PowerPyx's workaround is to quit to the main menu from the Game Over screen and load your last save from there, which resets the clock to that save's time, instead of pressing Continue. Pausing also stops the timer, but opening the inventory does not, according to PowerPyx.

Once unlocked, the Sweeper costs 1,000 CP and works on a fresh New Game. That makes it the standard weapon for S+ attempts: Game8's S+ advice is to clear the Village requests for 30 Spinels and spend them on a ticket for the Sweeper in the Castle. Our Professional S+ walkthrough builds an entire run around it.

The Infinite Rocket Launcher in New Game Plus

This is the one most people picture when they hear infinite ammo, and it is also the most expensive. The Merchant only sells it in a New Game Plus file, and in that mode he appears right after you leave the first house in Chapter 1 rather than waiting until Chapter 2. The price is 2,000,000 pesetas, dropping to 1,600,000 if you equip the Leon w/ Rocket Launcher charm, which comes from the token machine at the shooting range.

PowerPyx notes that most players cannot afford it after a single run, so plan on two playthroughs of treasure selling or a deliberate money run first. Because pesetas carry into New Game Plus, nothing you earn is wasted. The trade off is that it never works on a fresh save, so it cannot help with S+ ranks, but it turns New Game Plus Professional into a formality. The explosion can still hurt Leon and Ashley up close, which is why Game8 suggests keeping a handgun or shotgun for close quarters. Our New Game Plus guide lists everything else that carries over.

Cat Ears: Infinite Ammo for Every Gun

The Cat Ears accessory is the strongest version of infinite ammo in the game. Game8 describes it as letting all weapons reload indefinitely without using the ammo in your case, which covers everything except the regular single use Rocket Launcher. You still reload, but the reloads never draw from your stock.

The price is steep in effort rather than CP. You need an S+ rank on Professional, which means finishing a fresh New Game in under 5 hours 30 minutes with no more than 15 manual saves, and the accessory then costs 3,000 CP. In practice most players earn it last, after the Handcannon or Sweeper has already made ammo a non issue. The complete unlockables list shows the other accessories that unlock along the way, including the Chicken Hat from a Hardcore S+ clear.

A Sensible Order for Collecting Them All

Because each unlock makes the next one easier, the order matters more than raw skill. This sequence follows the logic of PowerPyx's roadmap and Game8's S+ advice, and it keeps every run useful:

1. Mercenaries first. Earn the three S ranks so the Handcannon is waiting in the Extra Content Shop before you even start the story.
2. A relaxed first playthrough. Clear every Village request, bank 30 Spinels, buy the Handcannon once you have 1,000 CP, and upgrade it with a ticket in Chapter 7. Sell treasures with gems inlaid and keep your pesetas growing.
3. New Game Plus on Professional. Use the carried over Handcannon (and the Infinite Rocket Launcher if you can already afford it) to finish under 7 hours. That A rank unlocks the Chicago Sweeper.
4. A fresh Hardcore run. Pull the Sweeper or Handcannon from the first typewriter, ticket it in the Castle, and aim for under 5 hours 30 minutes. The S+ reward is the Chicken Hat, which cuts damage taken.
5. The fresh Professional S+ run. Same plan with the Chicken Hat equipped and no more than 15 saves. The reward is the Cat Ears.

Steps four and five are optional if all you want is one gun that never runs dry. Most players stop after step two or three, and that is a reasonable place to stop: PowerPyx sums up a ticketed Handcannon as a magnum with infinite ammo that kills regular enemies in one hit.

Mistakes That Cost You Hours

• Spending Village Spinels early. The Punisher, Laser Sight and Treasure Map all tempt you at the first Merchant. If you want infinite ammo by Chapter 7, bank 30 Spinels instead.
• Chasing S+ in New Game Plus. S+ requires a New Game. Do your A rank runs in New Game Plus and your S+ runs fresh.
• Forgetting the Mercenaries download. It is a separate free add-on on the original platforms, and it is included in the Switch 2 Gold Edition.
• Confusing the two launchers. The regular Rocket Launcher is single use, sold from Chapter 5, and is not affected by Cat Ears.
• Starting over instead of continuing. Weapons and their upgrades carry into New Game Plus, so an upgraded Handcannon keeps its perk only if you continue from the cleared save rather than starting a blank file for a casual run.

Paid Exclusive Upgrade Ticket add-ons also exist. The Steam store lists single tickets, three packs and a five pack. PowerPyx notes that owning one lets you apply the upgrade at the first Merchant in Chapter 2 instead of waiting for the Castle, which shortens the Handcannon route considerably.

Skipping the Unlock Chain

All four routes demand at least one extra playthrough or a long Mercenaries session. If you just want to play with the ammo pressure gone, the store's RE4 Remake modded save has Standard and Hardcore slots at the first typewriter with unlimited pistol ammo, and a Professional slot at Chapter 2 with an unlimited Rocket Launcher. Its Separate Ways slots carry unlimited ammo for the pistol, sniper, shotgun and SMG.

The save is for PS4 and PS5 only, works only with the Remake, requires active PlayStation Plus on the same account (shared PS Plus will not work), and does not include the game. You can see every listing on the Resident Evil 4 Remake page.
