Playing soloJust you and random teammates — a simple plan
Your mission

Guard the back door so enemies can’t sneak up behind your team.

Your gadget: Trax Stingers. Spike carpets that slow and damage anyone walking through.

  1. Go this way: Emergency stairs (east) → top hallway
  2. Danger — an enemy often holds here: Tank anchor
  3. Plant the defuser here: Assembly, right behind the breach
  4. After the plant, hold here: Top hallway (east flank)
  5. After the plant, hold here: West stairs (Tank-side flank)

Don’t do this
  • Don’t leave your spot to chase kills.
  • Don’t stand where no teammate can help you.
  • 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

Stop defenders rotating into your back.

Team goal: Own 1F above the site, open the floors, then breach the Assembly wall from Assembly Delivery and plant Assembly.

Flank watch (your main job)

Hold the Emergency stairs / top hallway on the east side, and the west stairs behind the team.

With Trax Stingers: Throw Trax on the flank route marked on the map to slow roamers and make them noisy.

Plant support (if the team needs it)

Cover the planter from Assembly Delivery. After the plant, watch the breach and the floor hole from 1F.

With Trax Stingers: Throw Trax on the defuser’s path after the plant.

Spawn & approach

Generator (west) or Helipad (south). Both are close to the west side of the building and the Workshop / Control Room entrances.

  • Enter 1F from the West Side and clear Control Room, Storage and Workshop.
  • Use the west stairs to reach the Tank passage and Assembly Delivery.
  • Send one player down the Emergency stairs on the east side to cut the rotation and watch the flank.

Drone checklist

  • Assembly corners next to the Assembly Delivery wall, where anchors hide from the breach.
  • Tank and the Tank passage (a common second anchor spot).
  • The top hallway and the Emergency stairs for a roamer.
  • 1F Control Room and Storage before you stand on the floor above the site.

  1. Move: Emergency stairs (east) → top hallway
  2. Enemy likely: Tank anchor
  3. Plant: Assembly, right behind the breach
  4. Plant: Tank (backup plant)
  5. Hold: Assembly Delivery, watching the breach
  6. Hold: Top hallway (east flank)
  7. Hold: West stairs (Tank-side flank)
  8. Move: West stairs down from 1F → Assembly Delivery
  9. Drone: Drone Assembly corners
  10. Drone: Drone Tank
  11. Vertical: Open the floor from 1F Storage (above Assembly)
  12. Vertical: Open the floor from 1F Control Room (above Tank)
  13. Enemy likely: Assembly back-corner anchor
  14. Hard breach: Assembly wall — breach it from Assembly Delivery
  15. Move: Push through the breach into Assembly
  16. Hard breach: Second Assembly wall panel (if the first is denied)

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. Take 1F first: clear Control Room and Storage, the two rooms right above the basement sites.
  2. Open the soft floor above Assembly (from 1F Storage) and above Tank (from 1F Control Room).
  3. Two players go down the west stairs into Assembly Delivery; one comes down the Emergency stairs on the east side.
  4. The anti-gadget player clears the Assembly wall from Assembly Delivery, then the hard breacher opens it.
  5. Push Assembly through the breach while the 1F player shoots down through the floor. Plant and spread out.

Plant

Plant Assembly on the Assembly Delivery side, right behind the breach, so the players in Assembly Delivery and on 1F (playing the floor above) can both see the defuser. Tank is the backup plant once the Tank passage is clear.

Post-plant positions

  • Assembly Delivery, looking through the breach
  • Top hallway, watching the Emergency stairs side
  • West stairs (flank from the Tank side)
  • 1F Storage, playing the open floor above Assembly

Pitfalls

  • Throwing Trax where your own team needs to rotate.
  • Everyone going down one staircase — the other one becomes a free flank.
  • Everyone standing inside Assembly after the plant.
  • Going to the basement before 1F is clear — defenders on 1F shoot down through the soft floors.
  • Ignoring the east Emergency stairs flank.
  • Breaching Assembly while the Tank anchor can still shoot Assembly Delivery.

If defenders…

  • If the Assembly wall stays denied, play the floors: open both 1F floors and plant Tank from the west stairs.
  • The outer south wall of Assembly can also be reinforced or breached — check it on the drone before you plan around it.
  • If defenders extend up to 1F Control Room, take that fight slowly with three players first.
