Fortress favours attackers once they have space, so defenders contest Old Tower and New Tower early, then layer back into sites built to be sealed off.

Layout

Two floors with bombsites on both. Nearly every attack comes from one of two sides: New Tower and the Lobby stairs, or Old Tower with Laundry and its stairs below. Horse sits between them on 2F, and rappelling in the Courtyard is dangerous for attackers. On 1F, the Fountain room, the Showers and Laundry are the usual ways toward the lower sites.

Bombsites

2F Bathroom, 2F Commander's Office

The Office wall gets a rotation on the right and a reinforcement on the left, with footholes in the Master Bedroom wall and floor holes above the Lobby door so the defender on the stairs has support. Bathroom takes two reinforced walls and a rotation on the right. A rotation into Old Tower lets defenders shoot drones there before sealing it off with the spare walls. The Bedroom can't be planted in, so it stays open for defenders to pressure through.

2F Dormitory, 2F Games Room

Easy for attackers to surround, so both edges have to be contested. A rotation into Old Tower, plus a reinforced wall with a rotation in the hallway behind it, makes a strong spot to waste time. The breach is reinforced on the right with footholes on the left toward the Vending window. The Meeting wall stays soft, Bathroom gets two reinforced walls, and a defender over Horse uses vertical holes to watch Lobby before everyone falls back.

1F Waiting Room, 1F Cafeteria

The hardest of the three to hold. The Infirmary wall is opened, so attackers who take Infirmary still have to walk into Cafeteria or breach into Waiting. The three Oven walls and the double Hammam walls are reinforced, footholes cover the hallway attackers gather in, and a defender holds Fountain to stop a horizontal push through Oven. One or two players upstairs keep the hatch open and drop before they are cleared.

Holding the site

Contest the edges, waste time and layer back instead of bunkering early.
