According to Troy Baker: The Fate of the Character Played by Kevin Spacey, there is a different ending than what we saw in Call of Duty: Advanced Warfare.
Call of Duty: Advanced Warfare had a different ending than what we saw in the commercial version. Troy Baker, who was involved in filming the video scenes, says changes were made during post-production. If you have not yet completed the game, we recommend that you do not continue reading this section.
This was the deleted ending of Call of Duty: Advanced Warfare with Kevin Spacey
As the actor describes in conversation with YouTuber Dan Allen, the changes have been made to the scene where Jonathan Irons (played by Kevin Spacey) deactivates the exoskeleton suit for Mitchell and Gideon, the main duo. In the final version, we hear a speech, only to see Irons fleeing from the two soldiers paralyzed by the effect of the hacking shortly after. That chase ends in the resolution we’re all familiar with, where the player cuts his prosthesis to drop Irons into the void.
In the original version it was not. Let’s go back to the beginning of that scene. Irons gave a speech in which he said that “to make an effective move, you need a martyr.” Then he places the gun that we are holding on his head. “I know what I’m doing,” he claimed; Moments later, he let us pull the trigger.
Troy Baker explains that he wasn’t aware of the changes until the decision was made. “There is no way to do the original ending,” was the explanation Baker received from the study. The actor admits that he may be “in big trouble” for revealing the story, although he claims to be “completely true.”
Advanced Warfare was the first installment in the Call of Duty franchise led by Sledgehammer, who bet on changing the hitherto current formula. The presence of the skeletons allowed for mobility never seen before in the saga. Later projects, such as Infinite Warfare or Black Ops III, followed the trend in their own way.
