How to Get Infinite Ammo in RE9 (CP Costs & Unlocks)
Infinite ammo is one of the most sought-after unlocks in Resident Evil 9: Requiem, and earning it requires completing your first playthrough and spending Challenge Points (CP). This guide explains exactly how RE9 infinite ammo works, what it costs, and the fastest strategies to farm enough CP to unlock unlimited ammunition for every weapon in the game.
How to Unlock Infinite Ammo
Infinite ammo is not available during your first playthrough. You must complete the game at least once on any difficulty to unlock the Special Content menu. Once unlocked, navigate to the Special Content shop from the main menu to purchase infinite ammo using Challenge Points.
💡Choose the Right Ending
Make sure to choose the Release Elpis ending on your first playthrough. The true final boss fight awards significant bonus CP that you will miss if you choose Destroy Elpis. See our endings guide for details.
Challenge Points (CP) Explained
Challenge Points are earned by completing in-game challenges tracked in your Records menu. These range from simple tasks like defeating a certain number of enemies to complex feats like completing the game on Insanity difficulty. CP accumulates across all playthroughs and is never lost when spent.
How to Earn CP Fast
The fastest CP farming methods in RE9 are:
- Complete Insanity difficulty - Awards 40,000 CP in a single completion
- Speed run challenges - Completing the game under various time thresholds
- No-save runs - Finishing without using any manual saves
- Boss challenges - Defeating each boss without taking damage
- Collectible completion - Finding all Mr. Raccoon figurines and files
Infinite Ammo CP Costs
Every weapon in RE9 has a separate infinite ammo unlock. Here are the costs for all weapons available in the Special Content shop:
| Weapon | Character | CP Cost | Priority |
|---|---|---|---|
| Handgun (Standard) | Both | 15,000 | High |
| S&S M232 | Grace | 20,000 | High |
| W870 Police Shotgun | Leon | 30,000 | High |
| Requiem Revolver | Leon | 50,000 | Medium |
| Requiem Magnum | Grace | 50,000 | Medium |
| Sniper Rifle | Leon | 35,000 | Low |
| RPG (Rocket Launcher) | Both | 35,000 | Fun |
| All Weapons Bundle | Both | 150,000 | Endgame |
Best Order to Unlock Infinite Ammo
Not all infinite ammo unlocks are created equal. Here is the recommended priority order based on value and usability:
Priority 1: Handgun (15,000 CP)
The handgun is your most-used weapon across both characters. Infinite handgun ammo transforms your second playthrough, letting you conserve resources for crafting and upgrades instead. This is the single best first purchase.
Priority 2: W870 Police Shotgun (30,000 CP)
Leon's shotgun is devastating at close range and essential for crowd control. With infinite shells, Leon becomes nearly unstoppable during action sequences. Pair this with the best weapons guide upgrade path for maximum damage output.
Priority 3: RPG (35,000 CP)
The Rocket Launcher with infinite ammo trivializes every boss fight in the game. If your goal is farming subsequent playthroughs for more CP or completing speed run challenges, the RPG is your best investment after the core weapons.
⚠️RPG Does Not Count for Some Challenges
Using the RPG with infinite ammo disables certain no-damage boss challenges. If you are farming CP through boss challenges, use standard weapons first, then switch to the RPG for speed runs.
CP Farming Strategy: Fastest Route
The most efficient CP farming route combines multiple challenge completions in a single playthrough:
- Start a New Game Plus on Insanity (40,000 CP on completion)
- Aim for sub-6-hour completion (bonus 10,000 CP)
- Defeat the Commander without taking damage (5,000 CP)
- Choose Release Elpis for the final boss bonus CP
- Collect any remaining Mr. Raccoon figurines along the way
A skilled player can earn 60,000+ CP in a single optimized Insanity run, which is enough to unlock infinite ammo for the handgun, shotgun, and RPG in one go.
How Infinite Ammo Works In-Game
Once purchased, infinite ammo is toggled per weapon in your inventory menu. You can enable or disable it at any time during gameplay. Important details:
- Infinite ammo works on all difficulty modes including Insanity
- It does not disable trophies or achievements
- Each weapon must be unlocked separately unless you buy the All Weapons Bundle
- The weapon must still be found or purchased in-game before infinite ammo applies
- Infinite ammo carries across all New Game Plus cycles
