Microsoft will mark Halo's 10th anniversary with Halo Fest, a three day event taking place during the annual Penny Arcade Expo in Seattle this August.
Billed as "the largest and most expansive live Halo experience ever" over on Halo Waypoint, you can expect tournaments, exclusive panels and prizes.
Could it also see a new Halo title announced? Perhaps that rumoured remake of Combat Evolved?
"See why the last ten years of Halo were just the beginning," notes the Waypoint post.
PAX takes place between 26th and 28th August at the Washington State Convention Center in Seattle. Entrance to Halo Fest is included with a PAX prime badge.
