If you purchased a sealed copy of SOCOM 4 and redeemed the SOCOM 4 Pro voucher code at the back of the manual, a free DLC is waiting for you at the PlayStation Store.
As mentioned a couple of weeks ago, the Assault Pack DLC is now available on the PlayStation Store exclusively for the SOCOM 4 Pro members. The DLC will contain three multiplayer maps, Red Line, Double Cross, and Driftwood, as well as two fan favorite weapons, the M16 and AK-47.
For SOCOM 4 owners who purchased a used copy of SOCOM 4, the SOCOM Pro subscription is available on the PlayStation Store for $14.99.
