Call of Duty: Black Ops 4has released to plenty of fanfare, with the latest Treyarch title both offering new content with the likes of Blackout mode and evolving traditional content like Zombies, which has been an ever-present force in theCall of Dutyfranchise sinceWorld at War. Gamers who picked the game up can enjoy three different Zombies scenarios in their entirety, with many fans quickly discovering a plethora ofeaster eggswithin the undead mode.

Today, Treyarch has hyped up the fourth Zombies map, which is only available to gamers who purchased theBlack Ops 4Season Pass.

Those with the $50 pass can already access the new map, and Treyarch has just revealed a new trailer to show off what the rest of gamers are missing. The video features regular Zombies alumni Edward Richtofen, Takeo Masaki, Nikolai Belinski, and Tank Dempsey. It looks like Classified is chock-full of easter eggs too, though gamers have been slower to find them given the map’s paid barrier of entry.

Classified may look familiar to veterans of the franchise since it is a reworked version of Five, one of the maps fromBlack Ops. Sections of the map have been changed to give things a fresh perspective (in a similar manner toNuketown), allowing for gamers to better utilize some of the new perks and challenges.

TheBlack Opspass also includes 12 new multiplayer maps, 4 additional Zombies experiences, and 4 Blackout-exclusive characters. For the uninitiated, Blackout is Treyarch’s answer to the battle royale craze, and fans who want the pass-exclusive skins like Shadow Man will be forced topay a hefty priceto don the exclusive skins. Gamers who plan to spend plenty of time within the game will certainly get value for the $50 investment, and Treyarch will be hoping the above trailer for Confidential tips over a few consumers who may have been on the fence.

Call of Duty: Black Ops 4is available now on PC, PlayStation 4, and Xbox One.
