Sony Computer has announced the release of Killzone: Liberation for the PSP. Killzone: Liberation is the sequel to Killzone, a successful game for the PlayStation 2 that was released two years ago. It is anticipated that Killzone: Liberation will be much better on the PSP, with a third-person perspective, Wi-Fi functions, and all new environments.

In case you didn’t play the first Killzone, it kind of has a very modern warfare look to it. The sequel takes place in the same world as the first, a postmodern time where the ISA is at war with the evil Helghast. The Helghast are these guys that dress up like the Stormtroopers from Star Wars. Ruthless Helghast General Metrac (a human, apparently) has taken high-profile hostages in the City of Rayhoven. Hero Jan Templar is assigned to evacuate the city and rescue the hostages. In the game, you play Templar’s warriors, on mission of liberation. You can play in both online and offline modes, and have access to a great array of weapons and vehicles including tanks, sniper rifles, shotguns, and whatever else you can get the enemy with.

There are many different styles of gameplay as well. You can play alone, and, using the wireless feature, you can use two-player cooperative function for a single player mission. You can also have up to six players involved in games like Deathmatch, Team Deathmatch, Assault, and Capture the Flag.

Since Killzone:Liberation is designed by Guerilla, a wholly owned subsidiary of Sony Computer Entertainment Worldwide Studios, you know that Sony is going is market and promote this game up the yin-yang. The game is rated “T” for Blood, Language, and Violence, and it appears that rating is justified with the moderate amount of blood visible from the screenshots. Killzone: Liberation should be available wherever PSP games are sold at a suggested retail price of $40-50 USD.
