RE Requiem Grace Crafting Guide — Recipes and Hemolytic Injector Use
How Grace's crafting works in Resident Evil Requiem, what to make from Infected Blood, and when to spend a Hemolytic Injector. Resource-saving tips inside.
Grace doesn’t fight like Leon. She can’t upgrade her guns, she carries a measly eight-slot bag, and the game hands her almost nothing for free. What she has instead is crafting. Learn to lean on it and Grace becomes survivable. Ignore it and you’ll spend half the game running from zombies you can’t afford to shoot.
This is how Grace’s crafting actually functions in Resident Evil Requiem, what each recipe is for, and the right way to use the Hemolytic Injector without wasting it.
Why Crafting Matters So Much for Grace
The whole point of Grace’s design is scarcity. Eight inventory slots is almost nothing. You’re constantly choosing between carrying ammo, healing, key items, or puzzle pieces. There’s no room to hoard.
Because she can’t tune her weapons the way Leon can, raw firepower isn’t an option for her. Her edge comes from stealth and from manufacturing exactly the supplies she needs, when she needs them. That’s the loop: harvest, craft, survive, repeat.
The engine behind all of it is the Blood Collector, which Grace picks up in the Care Center. Once you unlock its crafting (there’s a short Analyzer puzzle gating it in the Blood Lab), it lets you convert a resource called Infected Blood into useful items.
Where Infected Blood Comes From
Infected Blood is Grace’s universal crafting material. You get it two ways:
- Blood Buckets scattered in the environment, which you tap with the collector for a quick refill.
- Zombie corpses. Put a zombie down and you can harvest its body for blood.
The corpse part is what changes everything. Every kill becomes a resource. Clear a room, drain the bodies, and you walk out richer than you walked in. It rewards you for engaging instead of always running.
The Crafting Recipes
Here’s what Grace can actually build from Infected Blood:
Handgun ammo. Your bread and butter. Grace’s starter pistol needs feeding, and the world doesn’t drop nearly enough rounds. Crafting ammo from corpses is how she stays armed. Make it as you go, not all at once, since slots are precious.
Hemolytic Injector. A defensive specialty item, covered in detail below. It stops a downed zombie from mutating. Rare to craft, so treat each one as valuable.
Ink Ribbon. Classic typewriter saves are in Requiem, and Grace can craft her own ribbons. On harder difficulties where saves are limited, this is a lifeline. Being able to manufacture the ability to save your game is a bigger deal than it sounds.
There’s also the Transfusion Bag, which refills the Blood Collector and restores Grace’s health. It’s the maintenance item that keeps the whole system running.
How to Use the Hemolytic Injector
This is the item people misuse most, so let’s be clear about it.
The Hemolytic Injector is jammed into a downed zombie. Doing so completely prevents that zombie from mutating into a worse, more dangerous form. A regular zombie you’ve shot down might get back up. It might also transform into something that takes a chunk out of you. The injector shuts that door permanently for that body.
The catch is that injectors are rare. You can’t afford to use one on every corpse, and you shouldn’t try. Most zombies don’t justify the cost. If a body is lying somewhere you’ll never walk past again, leave it. It’s not a threat.
The right use is narrow: a corpse blocking a path you have to take. Picture a downed zombie in a doorway or a tight corridor that you’ll be backtracking through repeatedly. If that one mutates while you’re squeezing past, it can genuinely ruin your run. That’s the body that earns an injector. Everything else can rot.
Save them for chokepoints. That’s the entire rule.
Resource-Saving Strategy
Grace lives on the margins, so efficiency isn’t optional. A few habits that keep you afloat:
Craft just-in-time. Don’t build a stockpile of ammo that clogs your eight slots. Make a handful of rounds before a fight you know is coming, then refill afterward by harvesting the bodies you just made.
Harvest everything you kill. Every corpse is free blood. Skipping a harvest because you’re in a hurry is leaving resources on the floor. Take the few seconds.
Pick your fights. The cheapest ammo is the ammo you never spend. Grace is a stealth character. Sneaking past a zombie costs nothing. Shooting one costs ammo you then have to re-craft. When in doubt, slip by.
Bank Ink Ribbons in safe stretches. When blood is plentiful and danger is low, craft a couple of ribbons so you’re never stuck unable to save before a hard sequence.
Keep at least one Transfusion Bag in reserve. Running the collector dry with no way to refill it, mid-crisis, is the worst-case scenario. A spare bag is cheap insurance.
Plan your crafting around the next save point, not the whole level. Grace’s run is a series of short survival windows. Figure out what you need to reach the next typewriter alive, craft that much, and stop. Building further ahead just locks up slots you’ll wish you had free when a key item turns up.
The Bottom Line
Grace’s whole survival kit runs through the Blood Collector. Harvest Infected Blood from buckets and corpses, then craft handgun ammo, Hemolytic Injectors, and Ink Ribbons as you need them. Don’t over-produce. Slots are tight.
The Hemolytic Injector is the item to be careful with. It’s rare, it stops mutations, and it should only ever go into a body that’s blocking a path you can’t avoid. Spend it anywhere else and you’ll regret it the moment a real chokepoint shows up. Play tight, harvest greedily, and Grace holds together just fine.
