I don't know if anyone here is excited about this like I am but Socom 4 has some DLC out now, and it can technically be gotten for free. The DLC is comprised of 3 new multiplayer maps favoring 8 vs 8 players (I thank you zipper

) called Red Line, Double Cross, and Driftwood. As well as a new gun for spec ops and insurgents, an M16 and AK47 respectively.
The DLC is free to purchase as long as you're a PS+ member, which we will all be soon, and you can keep the DLC as long as you entered the Socom PRO code from buying the game new. Here's the link from Sony's website if you're interested in reading the entire thing.
Welcome Back to SOCOM 4 - With Free Maps and Weapons!
