Saber Interactive released a brand new trailer for their upcoming zombie massacre, World War Z. Narrated by Saber’s Creative Director Oliver Hollis-Leick, the latest video gives a bit more of insight of how the chapters are broken alongside with a new look at the game’s gameplay.

The game’s co-op campaign features four episodes divided into three chapters each. Each episode is set in a different part of the world: New York, Jerusalem, Moscow and Tokyo. Before jumping in and butcher the army of the undead, players will need to select a class that suits your playstyle and an arsenal of weapons.

And the game will adapt based on your progress. If you’re too good, the A.I. director will throw you even more undead your way. On the flipside, if you and your partner are struggling, the game will give you additional firepower such as an extra auto turret or mortar.

Along with its campaign mode, World War Z will feature a handful of 4v4 Player vs Player vs Zombies modes such as Deathmatch, Domination and King of The Hill. There’s also new modes developed for the game: Scavenge Raid and Vaccine Hunt.

World War Z is set to stumble on PC, PS4 and Xbox One on April 16. Pre-ordering the game at retail will get players the free Lobo Weapon Pack, featuring three golden weapon skins and the dual-bladed Lobo spade.
