Hi-Rez Studios is getting spooky with Global Agenda this Halloween by introducing a new Defense Raid for players to take on. Starting on October 27th through October 31st, 2010, a special themed Defense mission will be added to the game's queue. But what's a Halloween event without a little loot? Global Agenda players will also have the chance to a new set of 13 different Halloween-themed masks. The masks will be available as random drops from the Halloween mission. And if you manage to drop the final boss in that mission you'll earn a guaranteed mask drop. Check out all the event details on the Global Agenda website.
