~Released on October 31, 2006, Killzone: Liberation is in my opinion one of the best shooters to hit the PSP system.
~The story follows the conclusion of the first Killzone, with the battles against the Helghast still raging on. Returning as captain "Jan Templar", your mission is to undertake a covert operation to stop Helghan leader "Metrac".
~The game's single player offers 4 acts, 5 total if you can manage to download it via WiFi or a local access point. There are 3 levels of difficulty: Easy, Normal, & Hard (for the more experienced players).
~Online players can choose a username and immediately join the fun. With a total of 8 playable maps, and 10 choosable weapons, it's hard to get bored on mulitplayer. Or if online isn't your thing, grab a buddy and play co-op.
~The gameplay and mulitplayer action is solid, but due to the occasional hackers and the fact that the server is down, Killzone Liberation has lost a lot of it's appeal. Nevertheless, I highly recommend that you check this title out. If not, I assure you you'll be missing out.
