Master Office / R6 Room
Draft – not yet verified in-gamePlaying soloJust you and random teammates — a simple plan
Destroy the enemy gadgets that stop your team from breaking walls.
Your gadget: EMP Grenades. EMP grenades that disable electronic defender gadgets (e.g. Bandit/Kaid electricity, Mute jammers). Remastered in Y10S4 – check the current charge count and behaviour.
- Go this way: Balcony Stairs → Mid Balcony → Gallery
- Send your drone here: Drone Server from Server Hallway
- Break this strong wall: Server wall — breach it from Gallery
- Go this way: Push the Gallery door into R6 Room
- Plant the defuser here: R6 Room, east end by the Gallery 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.
- Don’t use your gadgets too early — wait until your wall breaker is ready.
- Don’t waste gadgets on things that don’t matter.
- 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
Make the Server wall breachable.
Team goal: Take the east side (Gallery, Server, Six Hallway), open Server from Gallery and plant R6 Room with Server and Gallery covering it.
Anti-gadget (your main job)
Clear Bandit/Kaid/Mute on the Gallery → Server wall, then shields, cameras and traps in R6 Room.
With EMP Grenades: Your only job before the breach: throw EMP on the marked hard-breach wall (and any hatch you plan to open) so Bandit/Kaid/Mute can’t stop the charge. Call "wall clear" before the breacher plants.
Plant support (if the team needs it)
After the plant, hold Gallery and Server; deny the Six Hallway door.
With EMP Grenades: Save one EMP for the plant: jammers or cameras watching the plant spot can be disabled right before the planter commits.
Spawn & approach
South Dock (Balcony Stairs) and North Dock (Green Stairs / North Balcony).
- Balcony Stairs → Mid Balcony → Gallery: the main lane to Server and the R6 Room door.
- Green Stairs → Storage Hallway → Six Hallway for a second angle on the R6 Room.
- Only take the west side (Operational / Mezzanine) with drone support — defenders love it.
Drone checklist
- Server — defenders use it to shoot into both site rooms.
- Storage and Six Hallway (north side anchors).
- The R6 Room corners next to the Gallery door.
- Operational and Mezzanine for the west-side roamer.
Team map
- Move: Balcony Stairs → Mid Balcony → Gallery
- Drone: Drone Server from Server Hallway
- Hard breach: Server wall — breach it from Gallery
- Move: Push the Gallery door into R6 Room
- Plant: R6 Room, east end by the Gallery door
- Hold: Gallery, watching the R6 Room door
- Hold: Server, watching the breach and Master
- Move: Green Stairs → Storage Hallway → Six Hallway
- Drone: Drone R6 Room from Six Hallway
- Enemy likely: Storage anchor
- Enemy likely: Master anchor
- Enemy likely: Operational roamer
- Soft breach: Storage wall from Six Hallway — open it if left unreinforced
- Move: Push through the breach into Server
- Hold: Six Hallway (flank)
- Hard breach: Server → Master wall (for a Master 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
- Two players come up the Balcony Stairs to Mid Balcony and Gallery; one player takes Green Stairs to Six Hallway.
- Drone Server, R6 Room and Storage.
- The anti-gadget player clears the Gallery → Server wall, then the hard breacher opens it.
- Take Server, then push R6 Room from the Gallery door and Six Hallway at the same time.
- Plant R6 Room at the east end; open the Server → Master wall only if you go for Master.
Plant
Plant R6 Room at its east end next to the Gallery door, so the players in Gallery and Server can cover it. Master Office is planted through the Server → Master breach once the Master anchor is dead.
Post-plant positions
- Gallery, looking at the R6 Room door
- Server, watching the breach and Master
- Six Hallway / Green Stairs (north flank)
- Mezzanine / Main Stairs (west flank)
Pitfalls
- Using EMP before the breacher is ready — defenders can re-trick or replace batteries.
- Standing exposed on the breach wall while throwing.
- Throwing your gadget before the breacher is ready.
- Planting in the middle of R6 Room where Storage and Master can see it.
- Walking into Operational without droning — it is the defenders' power spot.
- Pushing R6 Room while Server is still held.
- Forgetting Green Stairs behind you.
If defenders…
- If the Server wall is denied, pinch R6 Room through the Gallery and Six Hallway doors and plant at its east end.
- If defenders stack R6 Room, open the Server → Master wall and plant Master.
- If the east side is locked down, take Mezzanine from the Main Stairs with drone support.
