Blundell describes Zombies Chronicles as a "love letter from Treyarch to the community." He says it's a good primer for newer fans too. "I felt like it was more important to give people the beginnings," he says.

The eight maps span a number of Call of Duty games, from Zombies' debut in World at War to Black Ops 2. They include:

Nacht der Untoten

Verruckt

Shi No Numa

Kino Der Toten

Ascension

Shangri-la

Moon

Origins

Zombies Chronicles will launch May 16th on the PlayStation 4, Blundell said. There's no word yet on how much it'll cost or when it'll come to other platforms. Treyarch will give more details during a livestream on Monday, May 8th.
