If a new teaser by Infinity Ward is any indication, then Call of Duty: Ghosts fans can expect the game's next DLC, Nemesis, to drop on August 5.
Nemesis is the fourth and final piece of downloadable for Ghosts through the Season Pass. In addition to the multiplayer maps and bonus weapons it'll probably bring to players, it also includes the finale to the episodic Extinction mode.
The actual teaser doesn't reveal any of the contents of Nemesis, but the description asks: "Where will you land on August 5th?" which could be an indication of its release.
As with previous Call of Duty DLCs, expect Nemesis to release first on Xbox One and Xbox 360. PS4, PS3 and PC can expect it to roll out one month later.
