Just in case you were unaware, yesterday Sony announced that the Cold Front DLC pack for SOCOM: U.S. Navy SEALs Confrontation landed on PSN.
New features and content include a new snow-filled Eastern European area with two maps and three classic SOCOM maps for 16 to 32 players.
There' also some new snow gear, a new mode calls Arms Run, and a thermal vision scope weapon attachment to track your enemies’ heat signatures.
All sorts of stuff contained in the DLC is listed over on the US PS Blog. You should go have a read.
