Look, there's only so many years you can keep shooting innocent defenceless animals before the formula gets a little stale. Which might explain why the next Buck Hunter arcade game — Big Buck HD Wild — is full of zombies.
Sure, there's a regular game mode where you shoot animals, but there's also a mode called "In Case of Zombies: Doe of the Dead", which as Arcade Heroes reports is not just full of "redneck zombies", but also zombie animals. Like zombie raccoons. And zombie chickens.
