Unless I'm reading it wrong.

This is going to be available on XB1 as a reward for a Challenge achievement.

If you are unaware XB1 lets games have time limited achievements that aren't for gamerscore but usually just bragging rights or in game items.

The Challenge is called 'The Grineer Invasion', starts in 13 days and requires the player to defend against 20 waves of defense on earth.

Possibly an Event or Tactical Alert as there have been challenges associated with both before.
