Lab Support / Lab

Draft – not yet verified in-game
Playing soloJust you and random teammates — a simple plan
Your mission

Break open a strong wall so your team can get into the bomb room.

Your gadget: S.E.L.M.A. Aqua Breacher. Throwable charges that hard breach reinforced walls in stages.

  1. Go this way: Yellow Stairs → Missile Hallway → Lockers
  2. Go this way: Courtyard Tunnel → Courtyard → Lab Exit
  3. Danger — an enemy often holds here: Lab anchor
  4. Break this strong wall: Lab wall — breach it from Lockers
  5. Plant the defuser here: Lab, next to the Lockers breach

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.

Don’t do this
  • Don’t use your gadget before a teammate destroys the enemy gadgets on the wall.
  • Don’t stand right in front of the wall when it opens.
  • Playing with strangers? Ping (mark) enemies and walls so your team knows.
Playing with a teamFull plan: every role, drones, breach, plant and what to do if it goes wrong

Open Lab from Lockers.

Team goal: Open the reinforced Lockers wall into Lab, pressure the Lab Exit doors and play the 1F floor above so the anchors are hit from three sides.

Hard breach (your main job)

Stand in Lockers on the wall shared with Lab (orange line). Breach on the "clear" call and let the entry player swing first.

With S.E.L.M.A. Aqua Breacher: Throw S.E.L.M.A. charges onto the marked reinforced wall after it is cleared of breach denial; one charge opens a hole, stacking more opens it wider. You can also open a second wall to split defenders.

Entry (if the team needs it)

Swing the breach with a trade partner, or push the Lab Exit doors when the breach opens.

With S.E.L.M.A. Aqua Breacher: Go through the hole with the first trade partner right after it opens.

Spawn & approach

Gate / South Dock for Yellow Stairs and Warehouse. The north side for the Courtyard Tunnel.

  • Yellow Stairs (or Warehouse from the docks) → Missile Hallway → Lockers: the main lane to the Lab wall.
  • Courtyard Tunnel → Courtyard → Lab Exit: a second lane onto the Lab and Lab Support doors.
  • One player on 1F Armory / Reception to open the hatches and floor above the site.

Drone checklist

  • Lockers and Missile Hallway — defenders like to hold these early.
  • Toxin and Stock, south of the site, where anchors hide.
  • The Lab Support corners next to the Lab Exit doors.
  • 1F Armory and Reception for defenders playing the floor.

  1. Move: Yellow Stairs → Missile Hallway → Lockers
  2. Move: Courtyard Tunnel → Courtyard → Lab Exit
  3. Enemy likely: Lab anchor
  4. Hard breach: Lab wall — breach it from Lockers
  5. Move: Push through the breach into Lab
  6. Plant: Lab, next to the Lockers breach
  7. Drone: Drone Lockers and the Lab wall
  8. Drone: Drone Lab Support through the Lab Exit door
  9. Vertical: 1F Armory hatch drops into Lab Support
  10. Vertical: Open the 1F Reception floor above Lab
  11. Enemy likely: Toxin player
  12. Hold: Lockers, watching the breach
  13. Hold: Missile Hallway (flank)
  14. Hold: Lab Exit, watching the doors

Team execute

  1. Two players come down Yellow Stairs (or in through Warehouse from the docks) into Missile Hallway and Lockers.
  2. One player takes the Courtyard Tunnel to Courtyard and Lab Exit.
  3. One player takes 1F Armory / Reception and opens the floor and hatches above the site.
  4. The anti-gadget player clears the Lockers → Lab wall, then the hard breacher opens it.
  5. Push Lab from the breach and the Lab Exit doors at the same time; plant near the breach.

Plant

Plant Lab close to the Lockers breach, so the player in Lockers and the player playing the 1F Reception floor above can both see the defuser. Lab Support is the backup plant from the Lab Exit doors.

Post-plant positions

  • Lockers, looking through the breach
  • 1F Reception, playing the floor above Lab
  • Missile Hallway (east flank)
  • Lab Exit / Courtyard (north flank)

Pitfalls

  • Throwing charges on a Bandit-tricked wall.
  • Using all charges on one wall when two openings are needed.
  • Breaching while Missile Hallway is still held behind you.
  • Swinging alone into a Maestro or Mira angle.
  • Attacking only from the docks — defenders stack Lockers and Missile Hallway.
  • Ignoring 1F: defenders there shoot down through the floor and hatches.
  • Forgetting the Yellow Stairs flank behind Missile.

If defenders…

  • If the Lab wall stays denied, push the Lab Exit doors and plant Lab Support under the Armory hatch.
  • If the 1F hatches are reinforced, open the Reception floor instead.
  • If Missile Hallway is locked down, move both dock players to the Courtyard side.
