There are three different weapon types that can be unlocked by completing certain challenges in Resident Evil 4 Remake. Each of these weapons will appear in your storage on any save file once unlocked, and getting their exclusive upgrade (either by using a Ticket or by fullly upgrading its stats) will grant unlimited ammo or durability for that chosen weapon.
Please note that while these weapons can still be used when attempting an S+ Rank run on any difficulty, there are a few challenges that will only reward you if you complete the story without using any of these bonus weapons.
Primal Knife
The Primal Knife can be unlocked by finding and destroying all 16 Clockwork Castellans, which appear once in every chapter (though a few can be backtracked to in a subsequent chapter). Once destroyed, they will never appear again on any playthrough. See our full Clockwork Castellan Locations Guide for details on how to find them. This special knife may not be as large as Krauser’s Fighting Knife, but its exclusive upgrade ensures it will never ever break!
| Primal Knife | Lvl 1 | Lvl 2 | Lvl 3 | Lvl 4 | Lvl 5 |
|---|---|---|---|---|---|
| Power | .8 | .9 (20000) | 1 (35000) | 1.1 (50000) | 1.2 (65000) |
| Durability | 1.6 | 1.8 (10000) | 2 (15000) | 2.2 (25000) | 2.4 (30000) |
| Attack Speed (fixed) | 1.1 | — | — | — | — |
| Exclusive: Becomes Indestructible for 10,000 ptas or 1x Exclusive Upgrade Ticket | |||||
Handcannon
The Handcannon is an extremely powerful magnum revolver weapon, boasting some of the highest damage possible in the game (aside from the Rocket Launcher). It can only be gained by completing the Main Story on Professional Mode without using any bonus weapons like the Primal Knife or Chicago Sweeper. However, it still means you can complete Professional Mode with any score ranking, or in New Game+ Mode with fully upgraded weapons for a better chance at beating the hardest difficulty the game has to offer. Once upgraded with its exclusive upgrade, you’ll never run of out Magnum Ammo when using this weapon!
With the Resident Evil 4 Mercenaries free update, it is now possible to unlock the Handcannon by getting an S Rank Rating on any character in each of the three stages!
| Handcannon | Lvl 1 | Lvl 2 | Lvl 3 | Lvl 4 | Lvl 5 |
| Power | 12 | 18 (40000) | 24 (50000) | 30 (90000) | 36 (120000) |
| Ammo Capacity | 5 | 6 (10000) | 7 (15000) | 8 (20000) | 9 (25000) |
| Reload Speed (# of rounds) | 1 | 2 (15000) | 3 (20000) | 4 (25000) | 5 (30000) |
| Rate of Fire | 0.52 | 0.55 (10000) | 0.58 (15000) | 0.61 (20000) | 0.65 (25000) |
| Exclusive: Ammunition never runs out for 10,000 Pesetas | |||||

Chicago Sweeper

The Chicago Sweeper is a special rapid-firing submachine gun, and can be unlocked by completing the Main Story on Professional Mode with at least an “A” Rank Rating. This means you will have to beat the game on the hardest difficulty (after beating the game once to unlock this mode) in under 7 hours — though you will be able to save as many times as you want during the run.
| Chicago Sweeper | Lvl 1 | Lvl 2 | Lvl 3 | Lvl 4 | Lvl 5 |
|---|---|---|---|---|---|
| Power | 0.40 | 0.8 (50000) | 1.2 (100000) | 1.6 (150000) | 2.00 (200000) |
| Ammo Capacity | 50 | 55 (10000) | 60 (15000) | 65 (25000) | 70 (30000) |
| Reload Speed | 0.78 | 0.82 (10000) | 0.86 (15000) | 0.89 (20000) | 0.93 (25000) |
| Rate of Fire (fixed) | 2.50 | — | — | — | — |

While Resident Evil 4 Remake includes lots of costumes and accessories as cosmetic changes for both Leon and Ashley, there are a few that actually give extremely useful bonus effects when worn, though you won’t know about them until you complete the challenge that unlocks them.
Note that these special accessories can be swapped out at any time during your game by pressing pause and going to the Extras Menu – with the exemption of Ashley’s Armor, which is a costume that can only be equipped from the Main Menu.
Remember: If a Challenge Run requires you to get an S+ Rank Rating on a certain difficulty mode, you can only attempt it on a fresh save file. This means you cannot do a New Game+ Run or use the Infinite Rocket Launcher to get an +S Rank Rating!
Wolf Tail
The Wolf Tail is a special accessory for Leon that greatly increases the power of his melee attacks (used after stunning an enemy by shooting them in the head or legs. It can be invaluable in higher difficulties, and especially when trying to complete any other type of Challenge Run.
In order to unlock it, you will need to complete the Main Story on Assisted Mode with an “S+” Rank Rating, meaning you will have to beat the game in under 4 Hours on a fresh save file! Be sure to plan your route carefully and avoid backtracking in favor of blowing past the opposition to reach the end fast!
Deer Antlers
The Deer Antlers are a special accessory for Leon that make all of your knife attacks more powerful (excluding stealth kills with the knife that will kill in one hit regardless). This accessory is incredibly powerful when combined with the Primal Knife’s indestructible upgrade, and should be considered when attempting a Minimalist Challenge Run.

In order to unlock it, you will need to complete the Main Story on Standard Mode with an “S+” Rank Rating, meaning you will have to beat the game in under 5 hours on a fresh save file! Be sure to run through the game a few times to figure out the best paths and where easy to grab treasure is, as you’ll want to stick to upgrading your pistol and shotgun quick, and take on a few side quests to earn Spinel for a Special Upgrade Ticket and increase the Riot Gun’s damage output to clear enemies faster.
Armor (Ashley)
The only costume to have a special effect attached to it, the Armor costume for Ashley will make her invulnerable to all damage, and make her unable to be carried (enemies may still try to pick her up, but she’ll immediately fall off and get back up). This costume can be essential for trying to get an S+ Rank on more difficult modes, as you will be able to run past enemies with Ashley without worrying about her falling behind or getting kidnapped.
In order to unlock it, you will need to complete the Main Story on Hardcore Mode with at least an “A” Rank Rating. You’ll have 10 hours to complete the game with any amount of saving, which is much easier than the 5 and half hours for the S+ Rank, so aim for that goal first.
Chicken Hat
The Chicken Hat is a comical looking cosmetic with an important bonus — it allows Leon to take reduced damage from all sources while worn. This makes it one of the best accessories to equip while trying to take on a Professional Mode Run, as enemies will deal a lot of damage on the highest difficulty.
In order to unlock it, you will need to complete the Main Story on Hardcore Mode with an “S+” Rank Rating. This means you’ll only have 5 hours and 30 minutes to beat the story – which is still a decent amount of time if you know where to go and where to find treasures to increase your money. You may even want to unlock the Chicago Sweeper or Handcannon first by playing on Professional Mode and get enough Spinel to unlock the unlimited ammo for the weapons.
Gas Mask
The Gas Mask is a special piece of headgear that changes how your aiming works. When equipped, it will activate Aim Assist (which is otherwise only available in the Assisted Game Mode). This can be a great way to get through tougher difficulties if you find aiming difficult — especially on console.
However, you can only unlock it be completing the Main Story on Professional Mode. This can be done with any score, so you don’t need to worry about a time limit or save limit. Take your time, use bonus weapons and other gear to help you out.
Cat Ears
The elusive and hardest to get accessory is the Cat Ears, which will give Leon infinite ammo for pretty much every weapon you can wield (except the single use Rocket Launcher). However, you’ll still need to manually reload your weapons, you’ll just never run of out ammo for them.

As it is arguably one of the best accessories, you’ll have to complete the Main Story on Professional Mode with an “S+” Rank Rating to unlock them, which means beating the game on the hardest mode in under 5 hours 30 minutes — with only 15 manual saves allowed. Since this is the toughest challenge of them all, and can’t be done on a New Game+ Run, you’ll likely want to rely on using the Chicago Sweeper once you get enough Spinel from completing Requests to get the Infinite Ammo exclusive upgrade.
