ijji.com's recently launched their free-to-play shooter Alliance of Valiant Arms in the US and now the game has added its first new gameplay mode. And what do you know? It looks like the game has succumbed to giving its players a variant of a "shoot zombies" mode.

The mode's actual title is Prison Break - Survival. The "zombies" are actually prisoners who have been infected by a biological agent that turns them into berserkers (more 28 Days Later than Dawn of the Dead). Players have to survive as long as possible against the wave of zombies . . . er, berserkers. You can check out the mode's full on action in the above video.
