Getting Started in Rat Lab

Rat Lab on Roblox (Evil Science group, place 105904727825849) drops you into a living lab with three jobs: Lab Rats who escape and return for revenge, Scientists who mutate and experiment, and Security who catch rats before they leave or re-enter armed. This getting-started guide covers your first hour without pretending promo codes exist when they do not, and without ignoring the session unlock reset that frustrates every new player.

Join and orient

Open Rat Lab from Roblox, load into a session, and identify which role you spawned or selected. The map is a laboratory complex with containment, science floors, and security choke points. Your first goal is not perfection—it is learning where the exit path begins, which tools unlock when, and how capture feels from both sides. Bookmark this wiki’s Guides Hub and skim Players so role pages stay one click away.

Community tip: many players find Discord invites through in-game prompts or creator links. If you need a visual walkthrough of joining community spaces, our related video covers Discord join steps; always verify invite links yourself.

Pick a role with intent

Lab Rats

Play Lab Rats if you want the main fantasy: break containment, complete a three-stage escape, reach the exit, then optionally return for revenge with weapons. Early pain points include getting netted or tased before stage two, underestimating vestless vulnerability to snipers, and dying on the revenge travel back into the lab. Deep dive: How to Escape and Lab Rats.

Scientists

Choose Scientists to run experiments, apply mutations, and chase Index completion. You care about specimen handling, mutation colour codes in the Mutation Index, and surviving rat revenge once escapes succeed. Deep dive: Scientist Guide and Scientists.

Security

Pick Security to patrol, capture, and shut down revenge runs. Learn that vest rats have roughly +50 HP, that a sniper one-shots non-vest rats, and that late-session rats with shotguns or OP mutations are a different fight than minute-three runners. Deep dive: Security Guide and Security.

Compare relative power on the Roles Tier List after you play each side once.

Session unlocks: the rule that defines Rat Lab

Almost every tool unlocks on a timer inside the current session and resets when that session ends, unless you own Forever gamepasses. Approximate milestones many players use:

Approx time	Examples
~5 minutes	Baton, Net
~10 minutes	Medkit, Taser, Body Armour
~15 minutes	Antidote, Pistol
~22 minutes	Rifles
~25 minutes	Mouse Trap
~30 minutes	Shotguns, Turret
~60 minutes	OP Mutations

Plan your first session around early tools: rats should pressure escape before Security’s mid-game guns stabilize; Security should delay with Net/Baton early and respect late firearms. Full notes and gamepass prices live on Tools & Unlocks and the Tools Tier List.

Paid options you will see in the store include Hazmat Suit (R$249), Armored Guard (R$249), Mutation Gun (R$299), MG (R$299), Sniper (R$399), Stronger Bite (R$75), Stronger Leash (R$99), plus Forever unlocks for tools. Buy only after you understand the free timer path.

Codes honesty check

There are no confirmed promo codes for Rat Lab on Creator Exchange at the time of writing. Do not chase random leaked strings. Our Codes page and How to Redeem stay ready for real releases. Do not confuse promo codes with Mutation Index colour codes—those track mutations and may be accelerated by the All Mutation Codes gamepass (R$2499). Read Mutations.

Badges to notice early

Keep an eye on: Test Subject, Through the Wall, Out of the Lab, For Science, New Specimen, and Caught One. Badge names hint at roles—escape-focused, science-focused, and capture-focused. Treat them as progress markers, not as a reason to skip learning routes.

First-hour checklist

1. Join a session and identify your role UI and nearest landmarks.
2. Survive five minutes; note when Baton/Net style tools appear for staff.
3. If Lab Rat, attempt stage one of the escape path; abort if Security stacks.
4. If Security, practice Net/Baton captures on early rats before guns dominate.
5. If Scientist, open Mutation Index terminology and avoid standing still during alarms.
6. After one escape or one capture, skim How to Escape or your role guide.
7. Check Updates so patch notes do not invalidate timers you memorized.

Common beginner mistakes

• Ignoring session resets and rage-quitting when tools vanish next join—expected design.
• Treating mutation codes as promo codes and spamming the redeem UI.
• Returning for revenge unarmed or without a route plan; revenge is optional and risky.
• Assuming vest and non-vest rats take equal damage; Security must adjust.
• Standing in open corridors once rifles and snipers unlock.

Where to go next

From here, Lab Rats should open How to Escape. Staff should open Scientist Guide or Security Guide. Everyone benefits from Tools & Unlocks and a glance at Scripts only if you already understand Roblox executor risks—this wiki prioritizes legitimate play. Return to the Guides Hub or Wiki anytime you need the full map of pages.

Play one full session on each role before spending Robux. Rat Lab rewards map knowledge and timer awareness more than impulse gamepasses.
