Lab Support / Lab
Draft – not yet verified in-gamePlaying soloJust you and random teammates — a simple plan
Help your team plant the bomb and keep it safe until it goes off.
Your gadget: Kawan Hive Launcher. Bee swarms that ping defenders who move through them.
- Go this way: Yellow Stairs → Missile Hallway → Lockers
- Send your drone here: Drone Lockers and the Lab wall
- Plant the defuser here: Lab, next to the Lockers breach
- After the plant, hold here: Lockers, watching the breach
- 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 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 Kawan Hive Launcher: Fire hives onto the defuser’s approach routes and into anchor corners after the plant so anyone who moves gets pinged.
Intel (if the team needs it)
Drone Lab, Lab Support, Toxin and Stock. Call any Mira or shield before the breach.
With Kawan Hive Launcher: Fire a hive into the anchor corner before entry to reveal defenders.
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.
Team map
- Drone: Drone Lockers and the Lab wall
- Drone: Drone Lab Support through the Lab Exit door
- Enemy likely: Lab anchor
- Enemy likely: Toxin player
- Plant: Lab, next to the Lockers breach
- Hold: Lockers, watching the breach
- Hold: Lab Exit, watching the doors
- Move: Yellow Stairs → Missile Hallway → Lockers
- Move: Courtyard Tunnel → Courtyard → Lab Exit
- Vertical: 1F Armory hatch drops into Lab Support
- Vertical: Open the 1F Reception floor above Lab
- Hard breach: Lab wall — breach it from Lockers
- Move: Push through the breach into Lab
- Hold: Missile Hallway (flank)

Team execute
- Two players come down Yellow Stairs (or in through Warehouse from the docks) into Missile Hallway and Lockers.
- One player takes the Courtyard Tunnel to Courtyard and Lab Exit.
- One player takes 1F Armory / Reception and opens the floor and hatches above the site.
- The anti-gadget player clears the Lockers → Lab wall, then the hard breacher opens it.
- 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
- Using all hives before the plant.
- Planting in the open middle of Lab.
- Leaving your drone in Missile Hallway where it gets shot.
- 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.
