That's exactly what the limited edition of Battlefield: Bad Company 2 -- which is now available to pre-order through Steam -- is bringing to the table. The bundle includes six pieces of equipment, ranging from improved armor on the player's vehicles, to a magnetic dart gun which helps the player track targets. We've contacted DICE to find out if these bonuses will be available during the game's multiplayer portion. We'd hate to have a repeat of the original Bad Company's boycott shenanigans.
Update: The pre-order offer is also available from Direct2Drive!
