Playing soloThe basics one player can do: walls, holes and where to stand
Your job
  • Reinforce the Assembly wall first — that is where attackers break in.
  • Stand in the Assembly back corner, not in front of the wall.
  • Listen for footsteps on 1F above you. They can open the floor.

  1. Reinforce this wall: Assembly wall to Assembly Delivery — The main breach — attackers stack in Assembly Delivery and blow it.
  2. Reinforce this wall: Second Assembly wall panel — Same room, second breach spot — close both.
  3. Reinforce this wall: Assembly outer south wall — Stops a surprise breach from outside.
  4. Reinforce this wall: Tank-passage wall to the Animus room — Attackers who drop the 1F hatch into Animus would open it.
  5. Open a rotation hole here: Tank passage ↔ Assembly Delivery (swing hole) — Lets the Tank player shoot attackers stacking on the Assembly wall.
  6. Hold this spot: Assembly back corner — Off the breach line; sees the plant spot.

How the five fit together

  • Mute (or Bandit / Kaid) keeps the Assembly wall safe; Jäger covers the plant.
  • Valkyrie puts cameras on the stairs so the anchors know which side is coming.
  • One roamer plays 1F Storage / Control Room to slow down the floor openers.

What attackers try — and your answer

  • Thatcher / Kali / Twitch clear the wall gadget → keep a second gadget hidden and deny late.
  • Zofia or Buck open the floor from 1F → put a roamer on 1F or play under cover away from the hole.
  • Attackers flank down the Emergency stairs → the Black Eye calls it; the Tank player rotates.

Mistakes to avoid

  • Leaving the 1F hatches open — attackers drop right next to site.
  • Nobody on 1F: the floors above Tank and Assembly can be opened freely.
  • Standing in Assembly Delivery — it is the attackers’ breach room.

2. Extend to 1F above site

Keep the same basement walls, but put two players on 1F Control Room and Storage to stop attackers from opening the floor over the site.

Your job
  • If you are on 1F, stay in the rooms right above the site.

How the five fit together

  • Two players hold 1F Control Room and Storage; one anchors Assembly; two roam.
  • Castle slows the West Side doors; Mute keeps the Assembly wall.
  • Call the fall-back early — the stairs are short, but you do not want to die on 1F.

What attackers try — and your answer

  • Attackers bring Fuze / Ying to clear 1F → fall back early and play the basement crossfire.
  • Vertical from 2F onto the 1F players → play corners away from the soft ceiling.
  • Breach on the Assembly wall → trick it with Mute and swing from the swing hole.

Mistakes to avoid

  • Staying on 1F too long and leaving the basement empty.
  • Barricading doors your own team needs to fall back through.
  • Forgetting the Emergency stairs flank on the east side.
