[edit] Mission Briefing

Solidify your defenses. Once the base is secure, search for and find the alien artifact that must be in the area.

Priority Critical:
The alien artifact must be found if it exists. We do not know what secrets it may hold - but it must not fall into Core hands.

Info Feed:
Despite our efforts, Core remains strong. Their activities have taken on a certain desperation. The beacon must be near!

Increased encounters with Scorpions lead us to believe that the beacon is very near.

To complete this mission you must capture the beacon and destroy all Core units and Scorpions.
