Though franchises like Gran Turismo, God of War, Ratchet and Jak, along with third-party franchises like Metal Gear Solid and Final Fantasy, are the tops of Sony's exclusive titles list and help sell more systems than pretty much anything else on any of its platforms, arguably the most important series from a technical standpoint is SOCOM. The series helped launch the PlayStation 2's Network Adapter and headset support, and pushed the PSP's networking capabilities further than any other title. And let's not forget that it also introduced the underutilized voice support on the handheld system. So it's no surprise that the series is seeing another PSP release this year that will continue to push some changes.
But this isn't the SOCOM that you might be expecting. Rather than sticking to its first/third-person shooter roots, SOCOM: U.S. Navy SEALs Tactical Strike is more of a strategy game, though one that features just as much action as its predecessors. Indeed, this isn't your father's turn-based strategy title where every move is thought out and planned to perfection, but rather a reactionary title that tasks you think on the fly while bullets whiz around your squadron's heads.
