Call of Duty’s mid-sea­son update for Sea­son 4 is on the way, and Activi­sion released a game­play trail­er for Black Op’s Cold War’s next Zom­bies map–Mauer der Toten. This map will arrive on July 15th with the Sea­son 4 Reloaded update.

Mauer der Toten trans­lates to Wall of The Dead, and is the third round-based Zom­bies map to arrive to Black Ops Cold War. It’s set in 1985 East Berlin fol­low­ing a zom­bie inva­sion which has rav­aged the city. The trail­er shows rooftop fight­ing and ziplines to help nav­i­gate the city and escape when needed.

The trail­er also shows a fan-favorite return­ing to Zom­bies mode–the Mule Kick perk. This perk allows play­ers to car­ry a third weapon and will be mak­ing its debut in Mauer der Toten. The new Won­der Weapon made a brief appear­ance as well, and it seems to be a an ele­men­tal pis­tol of sorts. There’s also a robot sol­dier by the name of Klaus that may be an ally, and quite pos­si­bly tied in with the new Won­der Weapon. Tre­yarch announced that Mauer der Toten’s quest­line hunt will start at 10:00 a.m. PT/ 1:00 pm ET Thurs­day, July 15th.

Mauer der Toten will con­tin­ue the Dark Aether sto­ry­line, and you can cur­rent­ly play through the option­al “Oper­a­tion Exci­sion” in Zom­bies Out­break, which is the pro­logue to Mauer der Toten.
