2 bomb sites on this floor share one plan.
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: Talon-8 Clear Shield. Deployable transparent shield.
Dining Hall / Kitchen
- Go this way: Junkyard → Small Tower
- Plant the defuser here: Dining, behind the Small Tower wall
- After the plant, hold here: Small Tower, watching the breach
- After the plant, hold here: Corridor by Showers, watching the Dining door
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.
Kitchen / Meeting Hall
- Go this way: Construction → Tower
- Plant the defuser here: Meeting, on the Stage side
- After the plant, hold here: Tower, watching the breach
- After the plant, hold here: Kitchen Corridor
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
Cover the plant from outside.
Team goal: Pick a side early — Small Tower for Dining / Kitchen, the Tower for Meeting / Kitchen — open one reinforced wall and add a second entry plus a 2F hatch.
Plant support (your main job)
Hold the breach from the tower side after the plant; deny the site doors.
With Talon-8 Clear Shield: Deploy the clear shield in the doorway or window that covers the plant spot so the planter is protected from the most dangerous angle.
Entry (if the team needs it)
Swing the breach with a trade partner while the second entry pushes.
With Talon-8 Clear Shield: Carry the shield into a doorway on the entry route to hold it safely while the team pushes past.
Spawn & approach
Junkyard for Small Tower. Bus for the Shower Corridor. Construction for the Tower and the Kitchen Corridor.
- Dining / Kitchen: Small Tower west door, the Shower Corridor, and 2F Kids above.
- Meeting / Kitchen: the Tower, the Kitchen Corridor door from the Garden, and 2F Attic above.
- Control White Stairs so defenders cannot rotate between floors.
Drone checklist
- Dining corners next to the Small Tower wall.
- Stage and the Split room in Meeting.
- Kitchen: anchors hide behind the counters.
- White Stairs and Security for the rotation.
Dining Hall / Kitchen — team map
- Move: Junkyard → Small Tower
- Move: Bus → Shower Corridor → Dining side door
- Enemy likely: Kitchen anchor behind the counters
- Move: Push through the breach into Dining
- Plant: Dining, behind the Small Tower wall
- Hold: Small Tower, watching the breach
- Hold: Corridor by Showers, watching the Dining door
- Drone: Drone Dining from Small Tower
- Vertical: 2F Kids hatch drops into Kitchen
- Hard breach: Dining wall — breach it from Small Tower
- Hold: White Stairs (flank)
- Hard breach: Kitchen wall — second breach from Security
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 Small Tower from Junkyard and the Shower Corridor from the Bus side.
- The anti-gadget player clears the Dining wall from Small Tower.
- Hard breach the Dining wall from Small Tower (the Kitchen wall from Security is the second option).
- Swing from Small Tower and the Dining side door together while 2F Kids opens the hatch over Kitchen.
- Plant Dining behind the wall; hold Small Tower, the Showers corridor and White Stairs.
Plant
Plant Dining behind the Small Tower wall once it is open — the default plant spot sits right behind that wall, so the Small Tower player covers it. Kitchen is planted after the Security-side wall opens.
Post-plant positions
- Small Tower, looking through the Dining breach
- The corridor east of Showers (Dining side door)
- 2F Kids, over the Kitchen hatch
- White Stairs (flank)
Kitchen / Meeting Hall — team map
- Move: Construction → Tower
- Enemy likely: Kitchen anchor behind the counters
- Enemy likely: Meeting anchor by Split
- Move: Garden → Kitchen Corridor → Meeting door
- Move: Push through the breach into Stage
- Plant: Meeting, on the Stage side
- Hold: Tower, watching the breach
- Hold: Kitchen Corridor
- Plant: Kitchen, next to the Meeting wall (backup)
- Drone: Drone Stage and Meeting
- Vertical: 2F Attic hatch drops into Meeting
- Hard breach: Stage wall — breach it from the Tower
- Hold: White Stairs (flank)
- Hard breach: Kitchen wall — open it from Meeting for a Kitchen plant
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 Tower from Construction; drone Stage, Meeting and the Kitchen Corridor.
- The vertical player takes the 2F Attic and opens the hatch over Meeting.
- The anti-gadget player clears the Stage wall from the Tower, then the hard breacher opens it.
- Push Meeting from the breach and the Kitchen Corridor door at the same time.
- Plant Meeting near Stage; hold the Tower, the Attic and the Kitchen Corridor.
Plant
Plant Meeting on the Stage side right after the Tower wall opens, so the Tower player and the Attic player (above the hatch) cover it. Kitchen is planted from Meeting once the Kitchen wall is open.
Post-plant positions
- Tower, looking through the Stage breach
- 2F Attic, over the Meeting hatch
- Kitchen Corridor
- White Stairs / Lobby (flank)
Pitfalls
- Placing the shield where defenders can simply shoot around it.
- Planting where the Kitchen Corridor sees you.
- Entering through one door alone.
- Not choosing a side early.
- Complicated calls in Meeting — Stage, Split and Meeting are enough.
- Ignoring White Stairs and the Kitchen Corridor.
If defenders…
- If Meeting is locked, switch to Kitchen through the Kitchen Corridor with the Kids hatch.
- If Small Tower is held, take the Shower Corridor first and breach Kitchen from Security.
- If the Stage wall is denied, use the Kitchen Corridor doors plus the Attic hatch.
