Rat Lab Gamepasses

Robux spending in Rat Lab only feels good after you understand the free ruleset: session tool unlocks reset every join, roles fight on a shared clock, and marketing names can sound like free gifts when they are not. This page is the fan wiki’s gamepass catalog and value guide—prices and dates reflect the mid-September 2026 wave players asked about most. Always re-read the live Roblox purchase modal before you buy; Evil Science can retune wording or cost.

Pair this catalog with the timer tables on Tools & Unlocks, role primers on Players, and official destinations on Wiki / Official Links. Escape and revenge still need routes (How to Escape, Revenge, Map) no matter what you own.

Mid-September 2026 pass wave (dated)

Date	Pass	Price	Player takeaway
7 Sep 2026	Body Armour Forever	R$59	Skip the ~10m Body Armour wait
7 Sep 2026	Mouse Trap Forever	R$149	Skip the Mouse Trap session wait
7 Sep 2026	Turret Forever	R$179	Skip the ~30m Turret wait
12 Sep 2026	Stronger Leash	R$99	Stronger control/leash fantasy
14 Sep 2026	All Mutation Codes	R$2499	Index convenience—not promo codes

Community stats around mid/late September hovered near ~669k visits and ~1.8k CCU—busy enough that paid skips feel tempting, but also busy enough that free players still learn the clock. Recheck Updates after each place push (including the 19 Sep 2026 update whose public notes were still thin when logged).

Forever tool passes vs session waits

Forever unlocks remove the wait for covered tools. Approximate free unlocks you are skipping:

Session mark	Tools often gated	Forever angle
~5m	Baton, Net	Early Security identity
~10m	Medkit, Taser (Body Armour Forever sold separately mid-Sep)	Mid control and sustain
~15m	Antidote, Pistol	First reliable firearms tempo
~22m	Rifles	Corridor denial
~30m	Shotguns, Turret (Turret Forever R$179)	Anchor defense
~60m	OP Mutations	Late science/combat chaos

Mouse Trap Forever (R$149) targets trap denial that free players usually see mid-to-late session. Body Armour Forever (R$59) is the budget Forever headline of the Sep 7 wave—strong value if you die mid-map without armour often.

Remember: Forever does not invent new win conditions. Vest rats still get about +50 HP; snipers still one-shot non-vest rats; escape is still three stages then optional revenge.

Cross-rank relative power on the Tools Tier List and Roles Tier List after you feel the free versions.

All Mutation Codes is NOT a promo code

Search traffic loves the phrase “mutation codes.” In Rat Lab that phrase collides with three different ideas:

1. Promo / redeem codes — typed gift strings. None confirmed working as of September 2026 (Codes, How to Redeem).
2. Mutation Index colour / specimen codes — gameplay tracking for scientists (Mutations).
3. All Mutation Codes gamepass (R$2499) — a paid convenience pass tied to mutation Index fantasy, not a free list of redeemable Robux gifts.

If a thumbnail says the pass “gives all secret codes,” it is SEO bait. Named mutations called out in video material include Verity and Dwarfism (Tiny Verity combo)—we do not invent a full Index colour bible here.

Value advice by role

Lab Rats

• Try a clean escape and one revenge return free before buying.
• Stronger Bite (R$75) is the usual low-risk rat spend.
• Forever firearms help revenge more than stage-one stealth—buy after you know map routes.
• Badges like Through the Wall and Out of the Lab still need route literacy (Badges).

Scientists

• Mutation Gun (R$299) and Hazmat (R$249) support the fantasy; All Mutation Codes (R$2499) is a whale/completionist outlier.
• Read Scientist Guide and Scientists before dropping four digits of Robux.

Security

• Armored Guard (R$249) and early Forever Net/Baton skips stabilize captures.
• Sniper (R$399) is powerful but device-dependent—mobile players should read Controls first.
• Turret Forever (R$179) and Mouse Trap Forever (R$149) punish revenge travelers hard.
• Caught One still requires timing, not only receipts (Badges, Security Guide).

Buy checklist (non-sales)

1. Play each role at least once via Getting Started.
2. Survive a session into ~30 minutes so you feel Shotguns/Turret without Forever.
3. Confirm the pass text in Roblox—do not buy from resellers or “cheaper pass” DMs.
4. Separate passes from promos: empty codes hub ≠ broken shop.
5. Recheck Updates the same week in case a place push retunes unlocks.

Spend after the clock makes sense. Rat Lab’s Forever wave is real convenience, not a substitute for learning stages, vest math, and when to abort a revenge run.
