Resident Evil Requiem Blood Collector Guide
The Blood Collector in Resident Evil Requiem, aka Resident Evil 9, is a Grace exclusive tool that lets you gather Infected Blood and craft powerful items. It is one of the most important mechanics during the Care Center section, and managing it properly makes a huge difference on higher difficulties.
This guide focuses only on how the Blood Collector works, how to upgrade it, and how to use it efficiently.
What Is The Blood Collector
The Blood Collector is a tool Grace obtains in the Blood Lab inside the Care Center.
It allows her to:
Gather Infected Blood from enemies and the environment
Store Blood units up to a set capacity
Use that Blood to craft ammo, injectors, and upgrades
Unlike Leon, Grace cannot craft advanced items without this system.
How To Get The Blood Collector
You obtain the Blood Collector during story progression in the Care Center’s Blood Lab.
Once acquired, you can begin collecting Infected Blood immediately.
How To Collect Infected Blood
After getting the tool, you can gather Blood from:
Certain defeated enemies that leave blood behind
Blood pools and stains in the environment
Buckets, tubs, or large blood sources
Transfusion Bags that refill stored Blood
Transfusion Bags restore Blood up to your current maximum capacity.
Blood Collector Capacity
By default, the Blood Collector holds:
100 units of Infected Blood
You cannot exceed this limit unless you upgrade it.
How To Increase Blood Collector Capacity
There are 2 upgrades available.
Matsuoka Override Manual
Purchased in the Parlor using 6 Antique Coins
Increases capacity by +50
Must be repurchased every playthrough
Matsuoka Master Manual
Unlocked in Special Content
Costs 1000 Challenge Points
Permanently increases capacity by +50
With both upgrades active, the maximum capacity becomes:
200 units of Infected Blood
Why Blood Collector Upgrades Matter
Higher capacity allows you to:
Store more Blood before crafting
Craft high cost items like Steroids
Save Blood for Requiem ammo
Avoid wasting excess Blood from Transfusion Bags
On higher difficulties, extra capacity gives you more flexibility and reduces backtracking.
Best Ways To Use Infected Blood
Prioritize crafting:
Steroids for permanent health increases
Stabilizers for better gun performance
12.7x55mm ammo for the Requiem
Avoid wasting Blood on low value items unless you are desperate.
Final Note
The Blood Collector is not optional if you want to optimize Grace’s sections. Upgrading its capacity early and managing Infected Blood carefully gives you stronger survivability and better boss damage options.
If you ignore it, you are making the game harder than it needs to be.
