History of Atrium

Overview

The Atrium is a Lost Sector in Trostland, European Dead Zone on Earth. It is entered from the back of the church ruins in the upper right of Trostland, where open hatches lead down a tunnel into the sector. It is held by the Fallen of the House of Dusk, and its boss is Skexis, Outcast Captain. It is featured in A New Frontier.

Walkthrough

The room is swarmed by Vandals. Shoot the nearby barrel early to clear the Dregs and a Shank, then use your Super and fight Skexis up close to kill him quickly. Skexis fires projectiles from range. Clear the remaining enemies to open the chest near the boss, which is the sector's reward.
