The next call of duty has been rumored to be named Call of Duty: Infinite Warfare, and it appears to be fairly close to a reveal.

The video that you can see below showcases what definitely appears to be a tease for the new game, featuring an enemy named "Settlement Defense Front." It appears at the end of the Nuketown map from the Call of Duty: Black Ops III DLC.

Not much is known about it for the moment, but the rumors about a science fiction settings seem to be getting closer to confirmation. This is just my speculation, but we could be looking at a story similar to Gundam, where interplanetary settlers go to war against the central government of Earth.
