RARE ARTIFACT DEFENSE EVENT– THIS WEEKEND ONLY Posted on 20/06/2013 - 14:28 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. WHAT: Rare Artifact Defense Event -- 3 Rare Artifacts will be scattered throughout special Defense Missions. Survive the specified number of defense waves to pick up the Corrosive Projection, Shield Disruption, or Infested Impedance Artifacts. WHEN: Friday June 21 @ 12:00 PM EDT until Monday June 24 @ 12:00 PM EDT Stay tuned to the Warframe Alerts, Warframe Nexus app, and in-game “Alerts” for “Secure the Artifacts” mission.
