A familiar location to anyone who’s filled up Jimmy Gibbs Jr.’s car, this Atrium features an expansive ground floor with an information kiosk that holds most of the items, and a nearby counter with the radio. Two more floors are accessed via staircases. Balconies stretch all around the main area of fighting, which is down below.
Flick on the radio close to the information kiosk (1), and then begin the fight in the atrium ground floor (2).
The upper balconies are an excellent place to dash to; they offer a couple of excellent shortcuts via the glass floors you can break and drop through, and gaps where you can jump down and move around the kiosk roof.
But the main cache of items and weaponry is near the Blue 22 car, so return here. Lay down a blanket of fire or other projectile weapons to nullify attacks in one direction (3), then concentrate on foes streaming in from the ground and above. Pay particular attention to ambushes from balconies. Finally, strafe around the ground structures to help avoid attacks (4).
