Killzone: Mercenary, the upcoming PS Vita installment in Sony's shooter series from Guerrilla Cambridge, has had its release bumped up a week. Previously pegged for a September 17 launch in North America, Killzone: Mercenary is now due on September 10.
In addition to moving up the date, Sony has revealed some pre-order incentives for Killzone: Mercenary over on the PlayStation Blog. The first perk is a 48-hour double XP boost, which spans all in-game contracts, bonuses and payouts. Joining that is additional in-game cash at the outset and a pre-order exclusive machine gun, the M224-A1.
