Your mission

Your gadget: Tactical Crossbow (fire & smoke bolts). Fires asphyxiating (fire) bolts and micro-smoke bolts.

  1. Go this way: Yellow Stairs → Missile Hallway → Lockers
  2. Plant the defuser here: Lab, next to the Lockers breach
  3. After the plant, hold here: Lockers, watching the breach
  4. After the plant, hold here: Lab Exit, watching the doors

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 plant in the middle of the room where everyone can see you.
  • Don’t stand in the same spot as your teammates after the plant.
  • 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

Make the plant stick.

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.

Plant support (your main job)

Cover the planter from the breach; after the plant, deny the Lab Support and Toxin doors.

With Tactical Crossbow (fire & smoke bolts): Keep your fire bolts for after the plant: shoot them onto the defuser’s approach path (doorways/hatches marked on the map) to buy time. Use smoke to cover the planter.

Anti-gadget (if the team needs it)

Clear Bandit/Kaid/Mute on the Lockers → Lab wall, then any Mira or camera looking at the plant.

With Tactical Crossbow (fire & smoke bolts): Fire bolts into corners where anchors or deployable shields sit right before entry to flush them out.

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. Drone: Drone Lockers and the Lab wall
  3. Hard breach: Lab wall — breach it from Lockers
  4. Plant: Lab, next to the Lockers breach
  5. Hold: Lockers, watching the breach
  6. Hold: Lab Exit, watching the doors
  7. Move: Courtyard Tunnel → Courtyard → Lab Exit
  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: Lab anchor
  12. Enemy likely: Toxin player
  13. Move: Push through the breach into Lab
  14. Hold: Missile Hallway (flank)

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.

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

  • Firing both fire bolts before the plant.
  • Smoking your own team’s sightline.
  • Planting in the open middle of Lab.
  • Clearing too early so a Bandit can plug back in.
  • 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.
