- Reinforce the Lab wall next to Lockers first.
- Stay out of the middle of Lab — the Reception floor above can be opened.
- Use the Lab Support ↔ Lab rotate.
- Reinforce this wall: Lab wall to Lockers — The main breach from the east side.
- Reinforce this wall: Lab wall to Toxin — Stops a breach from the south.
- Reinforce this wall: Missile wall to the Yellow Stairs corridor — Keeps attackers in Missile Hallway, into your crossfire.
- Reinforce this wall: Lab Exit wall to Filtration — Closes the north-west way to the Lab Exit doors.
- Open a rotation hole here: Lab Support ↔ Lab — Lets the two anchors swap rooms fast.
- Hold this spot: Lab Support, off the hatch — Covers the Lab Exit doors and the rotate.
Red A/B circles are the two bomb spots. Numbers on the map match this list. Positions are drawn on Ubisoft's official blueprint and are approximate.
- Reinforce this hatch: 1F Armory hatch (over Lab Support) — Without it, attackers drop onto Lab Support.
- Reinforce this hatch: 1F Reception hatch (over Toxin) — Stops a drop behind the Lab anchors.

- Gadget (Kaid): Claw on the Lockers wall — Electrifies the main breach wall.
- Gadget (Mira): Mirror on the Toxin wall — Watches Toxin and the south approach.
- Gadget (Maestro): Evil Eye in Lab, looking at the Lockers wall — Punishes the breach and shows the plant.
- Stand here: Lab Support, off the hatch — Covers the Lab Exit doors and the rotate.
- Stand here: Lab, north-west corner — Off the breach line; sees Lab Exit and the plant.

How the five fit together
- Two anchors in the site, two roamers on 1F above, one contests Lockers early.
- Kaid on the Lockers wall, Mira on Toxin, Maestro in Lab.
- The Missile wall stays shut so attackers funnel through Missile Hallway.
What attackers try — and your answer
- Hard breach from Lockers → Kaid claw and Maestro; trade from the corner.
- Lab Exit push from Courtyard → the Lab Support anchor holds the doors.
- Vertical from 1F Reception → the 1F roamers contest it; anchors play the edges.
Mistakes to avoid
- Nobody on 1F — attackers open Armory and Reception above you.
- Leaving the Armory hatch open over Lab Support.
- Opening the Missile wall and giving attackers a free lane.
