Auto Assault give a continued concentration on Ground Zero with a look at The Redline Outpost,one of the fifteen Outposts in the Ground Zero region (and fairly close to some Human bases).

As the three races encroached into the Ground Zero region they came upon the ancient, abandoned Outposts, remnants of the armies of the Old World. Those that study history believe the armies constructed these Outposts to help contain the Contamination and other strange occurrences in and around the region, and especially the giant crater that marks Ground Zero. Long abandoned, the Outposts were not defenseless; ancient computers still maintained the powerful defensive batteries, destroying any lifeform not deemed friendly that stumbled into the Outpost. Unfortunately for the three races, they were not considered to be friendly.

The Humans� foray into the area around the Redline Outpost area met with disaster. At first, they were met by hordes of deadly Contaminated creatures and the ultra-zealots of the Army of Justice. This concentrated resistance forced the Humans to retreat and regroup. Weeks later, reinforced by the elite unit known as the Red Brigade, the Human expedition successfully managed to establish a toehold in the northern side of Ground Zero. The Engineers then built several permanent bases and facilities to support these forward troops. Today the Red Brigade maintains a dominant presence, patrolling the region, maintaining the various facilities, and attempting to control the mutated wildlife as well as the legions of Justice followers.

Despite this presence, the Humans have yet to take complete control over the nearby Redline Outpost. Long-range reconnaissance indicated the existence of a control structure in one end of the Outpost that a driver may override and reprogram, but the attackers must destroy or otherwise occupy the defensive turrets first. Built against a range of mountains, however, the avenues of approach to Redline Outpost are limited. It is perhaps for this reason that the Outpost was nicknamed �Redline�, for it will take a fast and furious attack to capture it.
