Thermite · Lair 1F
2 bomb sites on this floor share one plan.
Draft – not yet verified in-gamePlaying soloJust you and random teammates — a simple plan
Break open a strong wall so your team can get into the bomb room.
Your gadget: Exothermic Charge. Hard-breach charge that opens a large walk-through hole in a reinforced wall.
Bunks / Briefing
- Go this way: South Dock → CCTV Stairs → CCTV Terrace
- Go this way: Green Stairs → Green Hallway
- Danger — an enemy often holds here: CCTV anchor
- Break this strong wall: Bunks wall — breach it from CCTV Terrace
- Plant the defuser here: Bunks, south-west part near the 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.
Armory / Weapon Maintenance
- Go this way: Shooting → Exit Tunnel → Exit
- Go this way: Blue Stairs → Blue Hallway
- Danger — an enemy often holds here: Armory anchor
- Break this strong wall: Maintenance wall — breach it from Exit
- Plant the defuser here: Weapon Maintenance, under the Operational hatch
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 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 the site wall from outside the site.
Team goal: Take 2F above the site first, then open one reinforced wall into the site and combine it with a hatch drop from 2F.
Hard breach (your main job)
Bunks: breach the Bunks wall from CCTV Terrace. Armory site: breach the Maintenance wall from Exit.
With Exothermic Charge: Stack on the marked hard-breach wall, wait for the anti-gadget player to call the wall clear, then place the charge on the centre of the wall. Stand off to the side while it burns — the hole becomes the team’s main entry.
Entry (if the team needs it)
Swing the breach with a trade partner.
With Exothermic Charge: Once the wall is down, you are often the closest player to site: clear the near corner of the hole with your team, not alone.
Spawn & approach
South Dock (CCTV Stairs / CCTV Terrace) or North Dock (Green Stairs) for Bunks / Briefing. Shooting (west) for Armory / Weapon Maintenance.
- Clear 2F above the site first — defenders there can shoot down on everything.
- Bunks / Briefing: CCTV Terrace from South Dock, plus Green Hallway from the north.
- Armory / Weapon Maintenance: Exit Tunnel from Shooting, plus Blue Hallway.
Drone checklist
- CCTV and Yellow Hallway for the Bunks anchors.
- Briefing's west side next to the Medical Hallway door.
- Armory and the Reception door into Maintenance.
- 2F Six, Server and Operational for defenders above you.
Bunks / Briefing — team map
- Move: South Dock → CCTV Stairs → CCTV Terrace
- Move: Green Stairs → Green Hallway
- Enemy likely: CCTV anchor
- Enemy likely: Briefing anchor
- Hard breach: Bunks wall — breach it from CCTV Terrace
- Move: Push through the breach into Bunks
- Hard breach: Briefing wall — second breach from Green Hallway
- Drone: Drone CCTV through its east door
- Vertical: 2F Six hatch drops into Briefing
- Vertical: Open the 2F Six floor above Bunks
- Plant: Bunks, south-west part near the breach
- Hold: CCTV Terrace, watching the breach
- Hold: Green 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
- Take 2F above the site first (Six, Storage, Server) — the site is won from the floor above.
- One player comes up to Green Hallway from the north; two players take CCTV Terrace from South Dock.
- The anti-gadget player clears the Bunks wall on the CCTV Terrace side, then the hard breacher opens it.
- The vertical player opens the Six hatch and floor while the breach goes.
- Push Bunks and plant near the breach.
Plant
Plant Bunks in the south-west part next to the CCTV Terrace breach, so the breach player and the player on the 2F Six floor both cover it. Briefing is the backup plant under the Six hatch.
Post-plant positions
- CCTV Terrace, looking through the breach
- 2F Six, playing the hatch and floor above
- Green Hallway (north flank)
- Yellow Hallway / CCTV (south flank)
Armory / Weapon Maintenance — team map
- Move: Shooting → Exit Tunnel → Exit
- Move: Blue Stairs → Blue Hallway
- Enemy likely: Armory anchor
- Hard breach: Maintenance wall — breach it from Exit
- Move: Push through the breach into Maintenance
- Hard breach: Armory wall — second breach from Blue Hallway
- Drone: Drone Armory through its west door
- Vertical: 2F Operational hatch drops into Weapon Maintenance
- Plant: Weapon Maintenance, under the Operational hatch
- Hold: Exit, watching the breach
- Hold: Blue 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
- Take the Shooting side and walk the Exit Tunnel to Exit.
- One player takes 2F Operational and opens the hatch over Weapon Maintenance.
- The anti-gadget player clears the Exit → Maintenance wall, then the hard breacher opens it.
- Push Maintenance from the breach while the Blue Hallway player pressures Armory.
- Plant under the hatch and hold from Exit, Operational and Blue Hallway.
Plant
Plant Weapon Maintenance under the 2F Operational hatch, next to the pillar, so the Exit breach and the player above both cover it. Armory is the backup from the Blue Hallway side.
Post-plant positions
- Exit, looking through the breach
- 2F Operational, playing the hatch
- Blue Hallway (north flank)
- Reception / Main Stairs (east flank)
Pitfalls
- Placing the charge before Bandit/Kaid/Mute is cleared — it gets fried or jammed.
- Standing in front of the wall where defenders can shoot through the burning hole.
- Breaching before 2F is clear — you get shot from above.
- Swinging into a smoked breach alone.
- Entering 1F without clearing 2F above the site.
- Pushing only one entry — both sites have several doors.
- Forgetting Blue Hallway / Green Hallway flanks.
If defenders…
- If the Bunks wall is denied, open Briefing from Green Hallway and plant under the Six hatch.
- If the Maintenance wall is denied, push Armory from Blue Hallway and drop the Operational hatch.
- If 2F is stacked, take it slowly with three players first.
