Resident Evil Requiem: How to Get Infinite Ammo Fast – Best CP Route

Why Infinite Ammo Matters in Resident Evil Requiem

After spending two full playthroughs fumbling around with challenges and wasting CP on the wrong unlocks, I finally found a clean, efficient way to grab the infinite-ammo RPG-7 and the key unbreakable weapons in Resident Evil Requiem. This guide is the route I wish I’d followed right after beating the game the first time.

If you’ve just seen your first ending and unlocked the postgame content, you’re at the perfect moment to plan your purchases. The wrong buy order can easily cost you an extra run or two; the right order lets you snowball CP and turn Insanity difficulty into a CP printer.

Below I’ll break down:

• Exactly how infinite ammo and unbreakable weapons work
• The true CP costs for every important unlock
• The buy order that gave me the fastest infinite RPG
• How to farm CP efficiently with speedruns and higher difficulties
• Common mistakes that made my first NG+ run way harder than it needed to be

How Infinite Ammo and CP Unlocks Work

First key point: you must finish the game at least once. Any ending is enough. After the credits, you unlock the Special / Additional Content menu, where you can spend CP (Challenge Points) on gameplay-altering bonuses.

CP is separate from your normal currency. You earn it by:

• Completing in-game challenges (combat, crafting, collectibles, etc.)
• Finishing the game on higher difficulties (like Insanity)
• Clearing speedrun objectives (e.g., under 4 hours)

Once the Special Content shop is unlocked, here are the key items relevant to infinite ammo and weapon durability, with the in-game CP prices I’ve confirmed in my own runs:

• Infinite ammo for all guns – 50,000 CP
• RPG-7 (base weapon) – 15,000 CP
• Infinite ammo for the RPG-7 (Leon) – 35,000 CP
• Infinite durability on hatchets – 20,000 CP
• Kotetsu (unbreakable knife for Grace) – 5,000 CP

There is a bit of confusion online: one French video mentions 100,000 “PC” total for the RPG-7 and other infinite ammo options, but every in-game menu I’ve checked (and multiple written guides) match the CP values above. I’ll stick with the in-game numbers I’ve personally seen.

Also important: buying an item is permanent. You don’t re-spend CP to reactivate it. Once purchased, it’s yours for every subsequent run, and you can toggle most of these modifiers on or off from the same Special/Bonus section without additional cost.

The Best Buy Order After Your First Ending

On my first clear I made the mistake of saving up for all-guns infinite ammo straight away. It felt like the “ultimate” reward, but it slowed my progress massively. The breakthrough came when I treated the unlocks like an investment ladder instead of a shopping list.

Step 1 – Buy the RPG-7 First (15,000 CP)

Your first priority should be the RPG-7 base weapon for 15,000 CP.

Why this first?

• Even without infinite ammo, it melts bosses and tougher enemies.
• It turns your next run into a semi-speedrun by deleting entire encounters.
• It’s cheaper than any infinite-ammo unlock and pays for itself in CP quickly.

For that second run, I equipped the RPG-7 primarily for boss fights and nasty chokepoints, while still using pistols, shotguns, and melee for trash enemies to avoid running the RPG dry too early. Think of it as your panic button, not your default gun, until you get the infinite upgrade.

If you finished your first playthrough with around 15,000 CP (which is very doable just by completing natural challenges), you can usually buy the RPG-7 immediately before starting NG+.

Step 2 – Use That RPG to Farm CP (Speedrun & Difficulty Challenges)

With the RPG-7 unlocked, your second playthrough is where you start printing CP. Here’s what I did:

• Drop difficulty to something you’re comfortable speedrunning on (I used Standard).
• Focus on a sub-4-hour clear to hit the speedrun challenge for roughly 20,000 CP.
• Plan your route so you minimize backtracking-RPG blasts cover your mistakes if you pull extra enemies.

My first “serious but not sweaty” speedrun with the RPG-7 landed just under four hours and netted me enough CP, combined with earlier challenge completions, to push toward the infinite RPG upgrade.

Step 3 – Buy Infinite Ammo for the RPG-7 (35,000 CP)

Once you cross the 35,000 CP mark, immediately grab Infinite Ammo for the RPG-7.

This is the single most important unlock in the entire game from a CP-efficiency standpoint. With infinite rockets, Insanity difficulty goes from “painful but possible” to “guided tour with occasional caution.”

On my first Insanity run without infinite RPG, I quit halfway through. With infinite rockets, I cleared it in one sitting and pulled in another hefty CP chunk (around 40,000 CP from difficulty + stacked challenges).

This is the turning point: once you have infinite RPG, every future run funds your remaining unlocks much faster than any other path.

Step 4 – Grab Infinite Hatchet Durability (20,000 CP)

Next, I recommend Infinite Hatchet Durability for 20,000 CP.

Even with an infinite RPG, you don’t want to rocket every basic enemy. A durable hatchet lets Leon reliably finish off stunned foes and clear weaker enemies without spending ammo-perfect for sections where splash damage would be risky, or you want to preserve the “feel” of the game instead of nuking everything.

In my third run, this combo (infinite RPG + unbreakable hatchet) let me:

• Use the RPG for bosses and big groups.
• Use the hatchet for stagger finishers and tight hallways.
• Save every other ammo type for fun rather than necessity.

Step 5 – Buy the Kotetsu Unbreakable Knife (5,000 CP)

At 5,000 CP, the Kotetsu knife for Grace is a bargain, and I’d fit it in as soon as you have the spare CP after the RPG unlocks. I grabbed it right after the hatchet.

Grace’s sections are where ammo feels the tightest, and relying on breakable knives is stressful. Kotetsu fixes that. My next Grace-focused run felt completely different: I could slash my way through weaker enemies, safely finish crawlers, and save bullets for emergencies.

Step 6 – Finally, All-Guns Infinite Ammo (50,000 CP)

Once you’ve bought the RPG-7, infinite RPG ammo, infinite hatchet durability, and Kotetsu, then it’s time to start saving for the luxury item: 50,000 CP for infinite ammo on all guns.

By the time I reached this point, I was consistently finishing runs fast on high difficulty with the infinite RPG, so 50,000 CP didn’t feel like a brutal grind. This unlock turns Resident Evil Requiem into a full-on sandbox: magnum spam, shotgun-only runs, whatever you want for achievement cleanup.

How to Farm CP Efficiently

Once I committed to the RPG-first route, CP farming stopped feeling random. Here’s the structure that worked for me.

1. Check Your Challenges After Every Clear

From the main menu, open the Special / Additional Content section (or equivalent) and look at the Challenge list. There are about 50 in total, and a lot of them will unlock naturally as you play:

• “Minimalist” style challenges (using fewer weapons)
• Enemy kill and headshot milestones
• Crafting and resource usage
• Collectible objectives (like Mr. Raccoon figures)

After each run, I’d scroll through and specifically note:

• Which challenges I was close to finishing
• Which ones stacked well with my next planned run (e.g., speedrun + minimal saves)

This let me passively stack CP rewards instead of chasing them one by one.

2. Speedrun for the Sub-4-Hour Challenge

The sub-4-hour clear is one of the best time-to-CP ratios you can get early on, especially with the RPG-7. I treated my first serious attempt as practice: I didn’t reset for minor mistakes, I just pushed through and learned which segments were the real time-sinks.

Key tips that helped me achieve it:

• Skip non-essential fights; if a door isn’t locked behind combat, run past.
• Use the RPG only for thick enemy clusters or bosses.
• Craft only when safe; menuing too much eats time.
• Memorize where key items are so you don’t over-loot.

That one run alone pumped enough CP into my account to make the RPG infinite upgrade realistic.

3. Use Infinite RPG to Dominate Insanity

Once I had the infinite RPG, Insanity difficulty went from being something I dreaded to my primary CP farm.

Before enabling it, I did a quick mental check:

• Infinite RPG toggled on in the Special Content menu.
• Hatchet / Kotetsu ready for ammo-free cleanup.
• Healing items stocked for the occasional surprise hit.

With that setup, bosses died in seconds and even the toughest enemy gauntlets became manageable. The CP payout from Insanity, combined with additional challenges you naturally complete on that difficulty, was enough to push me comfortably toward the 50,000 CP all-guns unlock.

Common Mistakes to Avoid

I made most of these errors myself before tightening up my route. Skip them and you’ll save several hours.

• Saving for all-guns infinite ammo first: 50,000 CP is a huge ask without an infinite RPG to help farm it. You’ll grind far longer than necessary.
• Overusing the RPG before it’s infinite: On my first NG+ I blew through rockets on trash mobs and ran out for a boss. Treat it as a limited nuke until you buy infinite ammo.
• Ignoring challenges: I left easy CP on the table by not checking which objectives I’d nearly completed. Always scan the challenge list after each clear.
• Wasting CP on non-combat extras too early: Cosmetics and minor buffs are fun, but buy them after your core power unlocks (RPG, durability, knives) if you care about efficiency.
• Trusting outdated or mismatched currency values: Some community content uses different labels or older numbers. Always double-check what the in-game CP shop shows in your version.

How to Activate and Use Your Unlocks

After you’ve purchased any of these bonuses from the Special / Additional Content menu, they don’t auto-apply in all cases. The game lets you treat them like optional “cheats,” so you can keep a purist run if you want.

What worked for me was:

• From the main menu, opening the same Special / Bonus section where I bought them.
• Checking each item’s status and using the provided toggle to enable or disable it.
• Starting a new run or loading a save after toggling so the changes are clearly in effect.

You’re never locked in permanently: you can do one “pure” Insanity run with no modifiers, then flip everything on for a victory lap NG+ where you rocket-jump your way through the story.

Wrapping Up – Your Postgame Power Curve

If you follow this order-RPG-7 → Infinite RPG → Hatchet durability → Kotetsu → All-guns infinite ammo—you’ll feel your power curve spike much earlier than if you chase the flashy 50,000 CP unlock first.

It took me roughly:

• 1 first-clear playthrough to unlock the shop and buy RPG-7
• 1 speedrun-focused NG+ to afford infinite RPG ammo
• 1 Insanity run with infinite RPG to fund durability items and most of the way to all-guns infinite

By then, every subsequent run was pure fun and experimentation instead of grind. If I can untangle my messy first attempts into a clean route like this, you absolutely can too. Focus on the RPG, respect your CP as an investment, and Resident Evil Requiem’s postgame opens up in a big way.
