One detail i like about this chapter is how every 33rd soldier that you faced are now organized and well-equipped. Throughout the game, the 33rd looked like a bunch of scavengers as most of them didn't wore their full military gear. Most didn't have helmets nor body armor. But now in this chapter, all of the soldiers you faced are wearing helmets and geared up in full military gear. It tells a lot of how they're desperate to take down Walker after he killed hundreds of their comrades.
Aside from the title of the video, one can really tell he’s playing in FUBAR because he stayed in the first building during the first firefight; if he had pushed to the pieces of cover before dispatching most of the enemies first he would be dead. (It happened a lot to me lmao)
