Zipper Interactive’s detailed over at the US PS Blog free DLC for PS Plus and SOCOM Pro users for SOCOM 4.
The map’s called Abandoned and was previously available only as a pre-order incentive, but will now be available for PS Plus members, and after one month, SOCOM Pro users will get it.
The developer also confirmed that new DLC was on the way with the SOCOM Pro Assault Pack, and it’ll come with three new maps: Red Line, Double Cross and Driftwood, as well as two new weapons: M16 and AK-47.
Go to the US PS Blog for more details.

still gotta finish the campaign, only got like 3 hours into it.
did not like it much though, they have taken it far too far away from the socom series!
i wanted socom, not your typical COD wannabe!
