Tank / Assembly
Draft – not yet verified in-gamePlaying soloJust you and random teammates — a simple plan
Find where the enemies are hiding and tell your team.
Your gadget: Gemini Replicator. Hologram you control to scout and bait defenders.
- Go this way: Emergency stairs (east) → top hallway
- Go this way: West stairs down from 1F → Assembly Delivery
- Send your drone here: Drone Assembly corners
- Danger — an enemy often holds here: Assembly back-corner anchor
- Plant the defuser here: Assembly, right behind 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.
- Don’t lose your drone in the first seconds — hide it in a corner.
- Don’t keep what you see to yourself. Tell your team or ping it.
- 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
Find the anchors and the roamer.
Team goal: Own 1F above the site, open the floors, then breach the Assembly wall from Assembly Delivery and plant Assembly.
Intel (your main job)
Drone Assembly and Tank from the stairs. Call the anchor spots before the breach.
With Gemini Replicator: Walk the hologram into site before the push to bait shots and reveal anchors.
Entry (if the team needs it)
Swing the Assembly breach with a trade partner right after it opens. Clear the corner by the wall first.
With Gemini Replicator: Use a hologram to fake the entry from one side while you push another.
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.
Team map
- Move: West stairs down from 1F → Assembly Delivery
- Move: Emergency stairs (east) → top hallway
- Drone: Drone Assembly corners
- Drone: Drone Tank
- Enemy likely: Assembly back-corner anchor
- Enemy likely: Tank anchor
- Move: Push through the breach into Assembly
- Plant: Assembly, right behind the breach
- Vertical: Open the floor from 1F Storage (above Assembly)
- Vertical: Open the floor from 1F Control Room (above Tank)
- Hard breach: Assembly wall — breach it from Assembly Delivery
- Plant: Tank (backup plant)
- Hold: Assembly Delivery, watching the breach
- Hold: Top hallway (east flank)
- Hold: West stairs (Tank-side flank)
- 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
- Take 1F first: clear Control Room and Storage, the two rooms right above the basement sites.
- Open the soft floor above Assembly (from 1F Storage) and above Tank (from 1F Control Room).
- Two players go down the west stairs into Assembly Delivery; one comes down the Emergency stairs on the east side.
- The anti-gadget player clears the Assembly wall from Assembly Delivery, then the hard breacher opens it.
- 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
- Using the hologram with no follow-up push.
- Losing your drone in the Tank passage before it reaches site.
- Swinging alone into a smoked breach.
- 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.
