Halo 3: ODST launches around the world in September, but players who pre-order the game at participating retailers will get a little bonus. An Xbox Live token will unlock Halo’s Sgt. Johnson as a playable character in the game’s Firefight multiplayer mode.

If you pre-order “Halo 3: ODST” at participating retailers, you will receive a token to unlock grizzled UNSC hero Sgt. Johnson as a playable character in Firefight.

Fan favourite and “Halo” series stalwart Sergeant Avery Junior Johnson is a tough-as-nails career Marine who has been in more life or death battles than you’ve had hot meals. He’s survived more infectious Flood outbreaks, greased more Covenant bad guys, and earned more medals than any other twenty soldiers. And now you get to walk a mile in his shoes.
