Rat Lab guides for escapes, mutations, and session tools
Source-backed guides for the three-role loop: escape stages and revenge for Lab Rats, mutation testing for Scientists, capture timing for Security, plus the timed tool unlocks that reset every session.

About This Game
Rat Lab is a Roblox experience by Evil Science where three roles share one lab: Lab Rats attempt to escape and take revenge or get tested on, Scientists create their own mutations and test them on lab rats, and Security stops rats from escaping or captures escaped rats.
Tool unlocks arrive the longer you play, and that time resets every session — so this wiki focuses on the per-session loop: the three-stage escape, mutation testing, capture timing, and the badges tied to them.

The three-stage escape path
Escaping as a Lab Rat is a three-stage path: break containment, cross the active lab, then commit to the final exit.
- 1
Stage one
Break immediate containment.
- Scout stage-one objectives before pushing.
- 2
Stage two
Cross the active lab interior, where most runs die to traps and nets.
- Time your vest pickup before contested mid-lab fights.
- 3
Stage three
Clear stage three and take the exit to complete the escape objective.
- Do not burn the exit window on a final-door 1v3.

How mutations work
Scientists create their own mutations and test them on lab rats; mutation play rides the same session clock as every tool.
Scientists create their own mutations and test them on lab rats, and mutation play rides the same session clock as every tool unlock.
- Promo codes and Mutation Index colour codes are different systems — no promo codes were confirmed on Creator Exchange as of September 2026.
- The All Mutation Codes gamepass (R$2499) speeds up Index colour tracking; it is not a promo-code list.
What resets when the session ends
Tool unlocks reset every join — each session is a fresh climb, and Forever passes are what persists.
Tool unlocks earned in a session reset when you leave; every join is a fresh climb.
- The unlock ladder runs from Baton and Net at about 5 minutes to OP Mutations at about 60 minutes, then starts over each session.
- Sniper, MG, and Stronger Bite are gamepass items with no known minute mark on the free session timeline.
Playing Security: winning the timer war
Security's best tools unlock later, so early-game positioning and entrance denial decide captures.
Timer asymmetry
Your best tools unlock later. Early rats can push escape stages before you have guns.
Vest rats (~+50 HP)
They soak shots that delete non-vest targets. Commit more ammo or combine control tools.
Revenge travel
Escaped rats come back with intent and weapons; your mid-map habits must flip to entrance denial.
Mobile inputs
Mobile Security should expect harder captures — win with positioning rather than blaming nets.
