ODSTs, your time has arrived. On September 21, the Experience Music Project and Science Fiction Museum and Hall of Fame in Seattle will be the place to be to celebrate all things Halo. Bungie and Microsoft invite Halo fans to take part in a celebration of the Halo franchise and usher in the release of Halo 3: ODST, the latest installment in the iconic video game franchise that has sold more than 27 million copies worldwide.

At the launch event, fans will have the opportunity to meet the creators who are driving the latest developments in the Halo universe, including Halo 3: ODST Creative Director Joseph Staten from Bungie and Halo Franchise Development Director Frank O Connor from 343 Industries. Fans will also receive hands-on time with Firefight and prepare for glory in an action-packed tournament for a chance to win coveted Halo -themed prizes. A select number of attendees will also be chosen for a special hands-on session with the Halo 3: ODST campaign.

Additionally, the event will feature special programming throughout the evening with panel discussions featuring Bungie and 343 Industries personnel. Through the panels, fans will learn more about the creation of Halo 3: ODST and get a sneak peek at the exciting new additions to the Halo experience such as Halo Legends, Halo Waypoint and more.

The launch event is free and open to the public.* The first 200 fans in line will receive a limited edition ODST T-shirt, so attendees are encouraged to arrive early. A panel of judges from Bungie and 343 Industries will be on hand to award prizes to the fans with the best Halo -themed costumes, so suit up and bring your best UNSC Marine/ODST/Master Chief/Cortana costume for all to see. During the event, all attendees are invited to tour the Science Fiction Museum and Hall of Fame free of charge.
