How to attack Nighthaven Labs Basement
The basement is small and the whole site sits under 1F Control Room and Storage, whose floors can be opened. The plan is simple: take 1F first so no defender can extend upstairs, open the floors above Tank and Assembly, then breach Assembly from Assembly Delivery.
Own 1F above the site, open the floors, then breach the Assembly wall from Assembly Delivery and plant Assembly.
Roles
Hard breach
Stand in Assembly Delivery on the wall shared with Assembly (orange line). Wait for “clear”, then breach.
Anti-gadget
Clear Bandit, Kaid or Mute gadgets on the Assembly wall from Assembly Delivery, then clear any camera or Mira watching the plant.
Vertical / soft breach
Open the floor in 1F Storage (above Assembly) and 1F Control Room (above Tank). Shoot down while the team breaches.
Intel
Drone Assembly and Tank from the stairs. Call the anchor spots before the breach.
Entry
Swing the Assembly breach with a trade partner right after it opens. Clear the corner by the wall first.
Flank watch
Hold the Emergency stairs / top hallway on the east side, and the west stairs behind the team.
Tank / Assembly
- Move: West stairs down from 1F → Assembly Delivery
- Move: Emergency stairs (east) → top hallway
- Drone: Drone Assembly corners
- Drone: Drone Tank
- Vertical: Open the floor from 1F Storage (above Assembly)
- Vertical: Open the floor from 1F Control Room (above Tank)
- Enemy likely: Assembly back-corner anchor
- Enemy likely: Tank anchor
- Hard breach: Assembly wall — breach it from Assembly Delivery
- Move: Push through the breach into Assembly
- Plant: Assembly, right behind the breach
- 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)

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
- 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
- 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.
