Security Guide for Rat Lab

Security in Rat Lab exists to capture escaped Lab Rats, protect the facility, and shut down the optional revenge return after a three-stage escape. You win by understanding session unlock timers, vest versus non-vest damage, and when to hold chokepoints instead of overextending into scientist halls. This guide is the staff hunter playbook.

Pair it with Security, How to Escape (know the route you are cutting), and Tools & Unlocks. New players should still skim Getting Started.

Mission profile

• Prevent stage progression when possible; a rat stuck in stage one is a free reset of pressure.
• Secure captures for progress toward badges like Caught One.
• After an Out of the Lab style escape succeeds, prepare for re-entry fights—not lobby AFK.
• Coordinate with Scientists so experiments do not block chase lanes; see Scientist Guide.

You are not a pure deathmatch class. Early tools emphasize control (Net, Baton); later tools emphasize lethality (rifles, sniper, shotguns).

Capture difficulty: why rats feel slippery

New Security players underestimate three things:

1. Timer asymmetry. Your best tools unlock later. Early rats can push stages before you have guns.
2. Vest rats (~+50 HP). They soak shots that delete non-vest targets. Commit more ammo or combine control tools.
3. Revenge travel. Escaped rats come back with intent and weapons; your mid-map habits must flip to entrance denial.

Tool timeline for Security

Unlocks are per session and reset unless Forever gamepasses apply. Approximate staff-relevant beats:

Time	Tools	Security use
~5m	Baton, Net	Primary early capture window—play aggressive patrols
~10m	Medkit, Taser, Body Armour	Sustain fights; Taser stops stage runners
~15m	Antidote, Pistol	Begin ranged denial
~22m	Rifles	Hold long labs and corridors
~25m	Mouse Trap	Lock flanks and revenge paths
~30m	Shotguns, Turret	Anchor sites; punish close returns
~60m	OP Mutations	Expect chaotic late power from multiple roles

Paid Security-leaning options include Armored Guard (R$249), Sniper (R$399), MG (R$299), Stronger Leash (R$99), and Forever unlocks so you skip the wait. Sniper one-shots non-vest rats—hold angles where non-vest runners must cross. Full prices and notes: Tools & Unlocks, rankings: Tools Tier List.

Vest math in fights

• Non-vest: sniper peeks and focused rifle fire end chases quickly.
• Vest (+50 HP): do not assume one clean shot; net/taser setups plus follow-up matter more.
• Never waste sniper timing on a vest rat if a non-vest runner is about to exit stage three.

Patrolling the three escape stages

Use the escape structure against them:

1. Stage one: flood early Net/Baton presence; this is your cheapest win rate.
2. Stage two: cover transitions where scientists cluster; call targets for teammates.
3. Stage three / exit: play denial, not random room clears. Late tools should already be online if the session ran long.

If a rat exits, rotate to revenge intercept paths immediately. The biggest Security failure is celebrating a partial chase while the escape finishes elsewhere.

Revenge defense checklist

• Pre-aim common return doors with rifle/sniper once unlocked.
• Place Mouse Trap / Turret logic on forced paths after ~25–30m.
• Keep Medkit discipline; revenge fights are longer against vested, armed rats.
• Do not ignore Mutation chaos—OP minute-sixty swings cut both ways (Mutations).

Badges and honesty about codes

Chase Caught One as a Security north star; facility badges like Test Subject still appear in the ecosystem. Escape badges on the server mean you are behind the curve.

There are no confirmed promo codes that spawn free Security kits. Ignore fake lists; use Codes only when real promos appear. Mutation Index codes are unrelated to your redeem UI.

Practice drills

1. Spend one session using only pre-15m tools to learn Net/Baton/Taser captures.
2. Spend one session holding stage-three denial with rifles.
3. After any escape, force yourself to guard return paths for two minutes before looting.
4. Duel vest vs non-vest intentionally so HP differences become instinct.
5. Review How to Escape weekly so rat meta routes stay fresh.

Security in Rat Lab is timer management plus route denial. Win early with control tools, win late with angles and traps, and never forget that a vest rat is a different animal than a sniper’s favorite non-vest runner.
