ORIGINAL STORY 5th May 2017: 2015's Call of Duty: Black Ops 3 is getting new Zombies mode DLC, which was announced last night on a T-shirt.
COD Blops 3: Zombies Chronicles was revealed on a shirt worn by Treyarch co-studio head Jason Blundell as he appeared in a video on the YouTuber JCBackfire's channel.
The pack launches on 16th May for PlayStation 4, with other platforms to follow.
Zombies Chronicles had been heavily anticipated by the community, not least on the COD Zombies reddit. Activision had also promised more Blops 3 content was on the way due to the game's continued popularity - and the large numbers of people who still play the game rather than upgrade to last year's Infinite Warfare.
Eight maps from Treyarch's past are expected to return for the DLC: World at War's Nacht der Untoten, Verruckt, and Shi No Numa; the original Black Ops' Moon, Kino der Toten, Ascension and Shangri-la, plus Black Ops 2's Origins.
It's not the first video game reveal engineered through the medium of clothing. Capcom's Resident Evil 2 remake was also announced via T-shirt.
Call of Duty: WW2, meanwhile, is the next in the series due for release. For details on that, we've gathered everything we know on COD: WW2's Nazi Zombies, beta, release date and more in our guide.
