May 31, 2007 - The release of http://psp.ign.com/objects/787/787457.html last October on the PSP provided a fresh third-person perspective on the Killzone franchise, which pitted the ISA and Helghast forces against each other. The Editor's Choice Award winner presented a large single player campaign, as well as multiplayer modes and the promise of future updates via downloadable updates. Well, looks like Guerilla Games just extended the war on Vekta for an additional tour of duty. Yesterday, the released the latest update for Liberation, which featured an additional single player chapter as well as new multiplayer maps.

Chapter 5 extends the storyline from the UMD and is designed to tie up the loose ends left at the end of the game campaign. In the downloadable campaign that's set underneath Sedah City, Sergeant Rico goes missing and players have to find out what happened to him over four new missions. These battles will take you over brand new terrain with new vehicles that you'll be able to control. You'll also be fighting your way through massive hordes of Helghast. However, players will be required to complete the standard single player game before they can gain access to Chapter 5. Multiplayer fans won't be left out either, because the update also provides two new maps for both Ad Hoc and Infrastructure mode play. The Prison and Construction Site should provide plenty of new zones to play Deathmatch, Capture the Flag and Assault in. Unlike the single player add on, players can jump into the two new maps immediately.

To download the update, players can update via the download option on the Killzone disc, or navigate over to Yourpsp.com or Killzone.com. We'll keep you updated on any additional downloadable packs for Killzone: Liberation as soon as they become available.
