Codemaster's "sequel" to Bohemia Interactive's 2001 classic has a limited edition that comes with an army helmet. A full-size army helmet, that looks like it's made from metal (plus a dog tag), giving the game a box that wouldn't look out of place in the Rock Band aisle. Or a stinky old army disposal store.
No word on price yet, or availability (this is a European version), but hey, on the bright side, unlike the MW2 box, this one will be made available to PC users.
this one is better from call of duty MW2 , Dog tags and Helmet looks cool
