I still have my BF2142 account, but if a lot of people get this, we can get a ton of awesome futuristic Battlefield gameplay out of this gem of a game. TITAN mode. That is all. Since it's the Deluxe Edition you gain access to the Northern Strike content and a some kit unlock points to start you off quicker to unlocking gear.
Buy it on Amazon (activates on Origin, duh) here.
Grab it if you want it. It's a buck, it's on PC, who cares?
