Those pre-ordering Halo 3: ODST from specific UK retailers will receive a playable Sergeant Avery Junior Johnson character.
He's the one that smokes cigars and grunts at Master Chief. And he has survived more Flood outbreaks and Covenant battles and earned more medals than anyone else. [Almost - sniff. - Ed] Apart from Master Chief, who would crush him like a fly.
Sgt. Johnson will be playable in Firefight, the new co-op survival mode where teams need to survive waves of baddies.
Exactly who the "specific retailers" will be is unknown. Neither ShopTo, GAME, Play, Amazon nor HMV mention the deal yet.
Halo 3: ODST will be released exclusively for Xbox 360 on 22nd September at full price.
