New nightmares arrive in Call of Duty: Ghosts‘ latest Extinction episode, Mayday.

The story continues with new terrors such as the insidious wall-crawling “Seeder” and the skyscraper-sized “Kraken.” And while the episode features new alien enemies, expect new weapon mods as well to help you and your fellow soldiers take on the alien horde.

Check out the alien-filled trailer below:

Episode 2: Mayday is included with Devastation, the second DLC pack for Ghosts, and will be released on Xbox 360 and Xbox One this Wednesday, April 3, with the DLC available to other platforms at a later date.
