The video is basically an interview. Throughout the interview, McGregor explains how he is a lifelong fan of the Call of Duty franchise and is honored to be a part of it. We also get to see him in action on the set, rehearsing some action sequences with a prop assault rifle, ground and pounding a mat, and giving a eulogy for fallen Marines. McGregor does not reveal his actual role in the game, but based on the ending of the video; he is most likely taking on an antagonist role. In the end, it shows him beating the holy hell out of the camera, or the main character. This heavily implies that he is something of an antagonist to the main character. 

This is exciting for fans of Call of Duty and the UFC. If players are going up against the featherweight champion of the UFC, they’re in trouble. However, this video gives fans another reason to buy the game, because the video reveals some stunning graphics, action, and characters.
