Fans of Killzone Liberation will be happy to know it is now available to PlayStation Portable (PSP).
Successful progress in the games gives you firepower and ammo capacity upgrades. You also get extra bonuses unlocked in-game or if you upload your results on the Killzone.com website, the bonus content is unlocked.
Multiplayer modes (six-player) are available as well and a new chapter of the game will also be available online next year, so look out for that one, Sony says.
RRP: $80
