A new Halo 3 double EXP weekend is going on right now through Monday morning, March 16. To participate, make your way into Halo 3's Legendary Brawl Double EXP playlist. But note, the Heroic and Legendary maps are required -- the Mythic maps are not necessary for this weekend's EXP earning, but "don't be surprised" when they show up in a future double EXP event. So, dust off your Mjolnir armor and bring along some extra teabags (for the caffeine boost, of course) because it's gonna be a long and (hopefully) memorable weekend.
