Call of Duty: Advanced Warfare‘s latest developer diary dives into the animation and art direction in Sledgehammer Games’ upcoming shooter.

You get to see a bit of the studio’s performance capture sessions, including shots of Kevin Spacey in his performance suit, which doesn’t look very comfortable. But, as demonstrated in Advanced Warfare’s E3 2014 gameplay demo, it seems to be paying off by showcasing some of the most realistic facial capture techniques we’ve seen in a video game yet.

Watch the video above, and if you missed it, you can also catch the previous developer diary on Advanced Warfare’s future tech right here.

Call of Duty: Advanced Warfare drops this November 4 on Xbox One, PlayStation 4, Xbox 360, PlayStation 3, and PC.
