Artifact Defense Event

The Artifact Defense Event started June 21st, 2013 at 5PM (GMT) and is supposed to end on June 24th at 5PM (GMT).

The dispatch from the Lotus: Attention all Tenno, ''We have found three rare Artifacts in transit throughout the system. We believe that enemy forces may have obtained knowledge of these shipments and are moving to intercept them. The Artifacts will be in transit for the next three days. If an Artifact is threatened, I will send out an alert beacon requesting defense forces. Attacks could come at any time and these artifacts are vital to our cause. Stay vigilant.''

This event is focused on special defense missions. Each of the event's missions reward one of three new Artifacts: Corrosive Projection, Shield Disruption, and Infested Impedance. These mission can be identified by their name, Secure the Artifacts.

All of these missions are of defense type and require Tenno to survive a variable number of defense waves.
