First spotted by CharlieIntel, two videos supposedly from a cancelled Xbox 360-era Call of Duty game called "Future Warfare" or "NX1" internally have been shared on Twitter. Their provenance has seemingly been confirmed by a former senior Neversoft developer who worked on the project.
The first video was shared by an account with the handle @mangafigurines (I've embedded a YouTube upload of the same video), and shows a first person cinematic sequence where the player's space suit is breached on the surface of the moon, and they have to flee into a nearby base while under attack.
