Blood Lab Tier List
Honest S–C rankings for a small testing arsenal — spawn guns first, optional Gamepass firepower second.
How to read this Blood Lab tier list
Blood Lab (BloodLab Testing) ships a deliberately small arsenal. You spawn with a Glock 17 and an AR. Stronger options are framed around optional Gamepasses rather than a huge loot table. That means any tier list must stay humble: we are ranking a testing-build roster, not a finished extraction shooter with fifty attachments.
Rankings below are community-preference style for hardcore co-op with friendly fire ON, no passive regen, and 4-player lobbies. Criteria weight:
- Controllability under FF pressure (can you stop shooting before a teammate crosses your barrel?).
- Mag / reload discipline (R to reload, V for fire mode when available).
- Value in mixed ranges while carrying bodies (G) or clearing tight interiors.
- Opportunity cost of spending Robux on a Gamepass gun versus learning the free spawn pair.
This is not an official GetRich Studios balance sheet. Patch the list mentally when the studio changes damage, recoil, or pass weapons.
S tier — primary workhorses
Assault rifle (spawn AR)
The free AR is the default “solve fights” tool for most BloodLab Testing sessions. Full-auto pressure helps when infected or hostiles close distance, and it pairs with the Glock when you need a quick swap. In a FF lobby, tap or short-burst more than you spray — the same magazine that wins a lane can also down an ally who leans (Q/E) into your sight picture.
Why S: always available, covers mid-range, carries the spawn fantasy of the test build without a purchase.
Premium Gamepass rifle (community preference)
When players buy a stronger Gamepass rifle, it usually sits at the top of personal loadouts: better sustaining fire, clearer “main gun” identity, and more forgiveness on tougher infected packs. Treat this as S only if you already understand FF discipline. A hotter rifle is a hotter team-kill machine.
Honest caveat: exact names and stats shift with studio passes; we describe the role (upgraded rifle) rather than inventing a fake SKU list.
A tier — flexible and situational stars
Glock 17 (spawn pistol)
The Glock 17 is underrated in panic. It is the clean secondary when the AR is reloading, when you are dragging a body, or when you need precise shots in a doorway without dumping a rifle mag into a teammate’s back. Crouch (C) and lean before you commit.
Why A: always there, safer for precision, excellent as a discipline teacher.
Gamepass SMG (hypothetical / preference tier)
Community talk around upgraded SMGs places them in A: strong in interiors and spore-adjacent tight spaces mentioned in older titles, weaker if you insist on long hallway laser fights. Hip-fire comfort is high; FF risk stays high because time-to-kill is short.
B tier — specialty picks
Gamepass shotgun (preference tier)
Shotguns shine for door checks and last-second peeks, then fall off when the lobby spreads out. In a 4-player stack doing coordinated clears, one shotgunner can anchor entry while AR teammates cover angles. Solo shotgun as your only plan is B — feast or famine.
“Hot” experimental passes
Anything marketed as novelty firepower without clear recoil control belongs here until the community proves it. Testing builds change; do not sink Robux on day-one hype without a private-server feel for spread and FF safety.
C tier — avoid as your identity
Panic spray with any gun
Not a weapon — a playstyle. Holding M1 through a teammate carry animation, reloading late every fight, or ignoring V fire-mode options parks you in C regardless of Gamepass spend.
Ignoring heals and food while chasing DPS
Bandages (~every 3 minutes on mirrored spawn notes) and food (~every 2 minutes) keep you in the fight longer than one extra damage attachment. A player who buys a rifle then dies to neglected heals is still C-tier impact.
Loadout recommendations by role
| Role | Suggested pair | Notes |
|---|---|---|
| Anchor / entry | AR + Glock | Default spawn; master it before buying passes |
| Paid rifler | Gamepass rifle + Glock | Communicate before long sprays |
| Interior clearer | SMG or shotgun pass + Glock | Call “holding door” so allies do not cross |
| Support / carry focus | Glock primary during carries | Tap Q to drop safely; do not ADS into allies |
Cross-check survival habits in Getting Started — controls, bandage rules, and FF awareness matter more than a single tier letter. For stacking etiquette, see the Players Hub.
How this list will evolve
BloodLab Testing last showed public update activity through 2024-09-16 after a 2024-04-02 launch. Related open-alpha The Last Of Blox may absorb lessons from this lab. When weapon rosters grow, this hub will split into deeper pages; until then, one honest board beats a fake 30-gun chart.

Quick verdict
- S: Spawn AR; well-used Gamepass rifle.
- A: Glock 17; Gamepass SMG in CQC.
- B: Shotgun specialty; unproven novelty passes.
- C: FF negligence and heal ignorance, any gun.
Master the free pair first. Buy power second. Keep your muzzle out of friendly spines always.
Frequently Asked Questions
Quick answers for Blood Lab survivors.
What guns do I spawn with in Blood Lab?
BloodLab Testing gives a Glock 17 and an AR as the standard spawn loadout. Stronger weapons are typically optional Gamepasses.
Is the Glock actually usable or just a backup?
Usable. It ranks A here for precision, reloads, and safer shots while carrying or clearing doors under friendly fire.
Should I buy a Gamepass gun immediately?
Only after you can control FF and bandage timing with the free AR/Glock. A stronger rifle multiplies mistakes as much as damage.
Will this tier list match The Last Of Blox?
Not 1:1. The Last Of Blox is a larger open-alpha fantasy. Use this list for BloodLab Testing; re-evaluate weapons there separately.
