"Base Relocation Disabled Tomorrow As Base Invaders III starts on Thursday, the relocation feature will be turned off tomorrow (Wednesday) to allow sectors time to prepare for the event. The relocation feature will be reactivated soon after Base Invaders III has ended."
 
April 19th

The Forsaken Council has learned that Draconian Commander Maximilian Vassago is out to assert his power in the world. Our intel is sketchy, but it seems he plans on building numerous Outposts on April 19th. We must strike these sites before they're fully operational. Your daily participation in this attack will be rewarded with a Damage Quota Bonus. Will you join us?

Sectors 101-200: 10am PST
Sectors 201-300: 11am PST
Sectors 301-400: 12pm PST

**All players will have 96 hours to execute this coordinated attack.
