Background
The ancient fortress of Vestmarch rests on the far edge of the Quadrant.
As one of the great bastions that protects the Quadrant from afar, the space around Vestmarch is constantly at threat.
The fortress itself is embedded deep within the surface of a moon, protecting it from attack.
The Templar Fleet patrols the space around Vestmarch, repelling xenos invasion at every turn.
A Siege Begins
While hidden and protected, the Fortress of Vestmarch is far from impervious to attack.
While the Templar Fleet is at large in the nearby space, and pursuing a roving xenos enemy, the Fortress comes under mighty attack.
The entire super-structure shakes with a blow, and klaxon roar to life. Down the barren stone halls, the clash of battle and the roaring boom of Leviathan cannons sounds.
Primary Objective
The super-structure of the Fortress has suffered damage, temporarily disabling the communication lines.
Xenos are pouring in from all sides.
As a squad separated from the main fighting force, you must retreat toward the Secured Inner Bastion. The main battle force will need every Hydra Cannon available for the fighting ahead, and a quick but careful retreat is critical.
Briefing and Map
Fight your way to the Main Storage Cavern.
Secondary Objectives
Prevent the death of your Hydra Cannon carrying Templar.
