1:12-1:30 feels like something you would see in an old fps from the 90s that was given a graphical upgrade and not much in terms of animations for the characters moving, not that it is bad or anything, i just find charming in a way.
This feels like an intro cinematic made in the late 90s for an fps game for personal computers and the only way to know what is going on is to read the manual. Honestly, i am all here for it, well done.
Nice animation, but I think it would yield better results if you made the power armor into components attached to a rigged model. There is a lot of warping on the surface going on, clipping is easier to hide.
