Activision demonstrates what the Zombie map Der Eisendrache from the highly anticipated "Call of Duty: Black Ops 3"Eclipse DLC will be all about and the horrors it is about to unleash in a brand new trailer.

In the clip that ran for almost two minutes, the "Call of Duty: Black Ops 3" publisher teased what players will be dealing with in the mysterious island of Zetsubou No Shima.

"Beneath the shadow of an evil, a new enemy has arisen," the voiceover ominously announces.

The narrator refers to the zombies, which are among the horrendous products created in the test beds of an underground research lab that trifled with Element 115. Apart from zombies, "Call of Duty: Black Ops 3" players will see a malformed version of nature in the Eclipse DLC.

The trailer also shows ways to take down the zombies. There's the tried-and-tested headshot, but the trailer also teaches a more horrifying and stomach-lurching way to get the flesh-eaters' heads off.

Zetsubou No Shima also appears to be home to other deadly living things like plants and foliage that are supposed to be harmless, but were made lethal due to the experiments. All over the strange city are destructive traps that "Call of Duty: Black Ops 3" gamers must be wary of, too.

Der Eisendrache is one of the five maps coming to "Call of Duty: Black Ops 3" by way of the Eclipse DLC. The other four are Verge, Rift, Spire, and Knockout, each one presenting unique challenges and opportunities to players.

It is worth mentioning that Verge is a reimagined version of the iconic Banzai map from "Call of Duty: World at War." Players who pre-order the "Call of Duty: Black Ops 3" Eclipse DLC this week are getting the Zetsubou No Shima dynamic system theme for free.

This theme "depicts a closer look into the twisted world of the 'Zetsubou No Shima' Zombies experience,"
