Judge Dredd vs Zombies is an action game set in the post-apocalyptic and dystopian future of the eponymous 2000 AD comic books. As the titular law enforcer, the player must navigate various levels to eliminate the zombies invading Mega City One. While in 3D, gameplay is very similar to arcade classics such as Alien Syndrome.
To unlock the exit lift, the player must destroy all zombies in the level, while trying to perform chain kills and combos to increase his score. The legions of the undead come in various shapes and sizes, needing more or less hits to be destroyed. To deal with the threat, Judge Dredd can choose between several weapons at the beginning of a level, including his trusty MkII Lawgiver pistol, a shotgun, a sniper rifle, and a rocket launcher. Various items can also be picked up in the levels, such as ammo, judge badges and medkits.
There are 3 episodes to be completed, with each consisting of 10 levels.
The game features in-game purchases to unlock all levels and upgrade Dredd's arsenal.
