Battlefield V

[Husar]

Bionic arm, vehicles, and some of the stuff going on in the background.

I didn't see any of that. The arm is not a bionic arm, it's like these ones, purely mechanic:



I'll have to look again about the futuristic vehicles, they looked mostly real to me.

edit: I don't see anything that didn't exist. Early on there are British tanks, Churchills and maybe a Matilda or so, then there's a Tiger and later on a Brummbär or Sturmtiger in the background. A few vehicles in between that are hard to identify, but overall they seem real, including the airplanes. I remember there's a Me 109 and the V1, both of which existed.

Of course the "stuff going on" is not very realistic, even in the foreground.
