If somebody described me it in words, I would probably expect it to be a gimmick, a flashy surface level effect, a shock value. It's none of these! It works as an expression, as a new visual language, it feels sincere and raw.
I'm not a big fan of translating game experiences into words, so please regard my comment as a clumsy attempt to describe my raw impressions, not as some kind of review or analysis. It's especially absurd to do it with this particular game. Finding it's own language, which is only possible in the medium of videogames is exactly what this game is doing and it does it extremely well. It creates meaning inside the medium and doesn't need translation. Nevertheless here it is)
War as a discotheque. A party. You know, everyone looks so cool and full of grace and sexy and then suddenly strobe light turns off and for a short period of time you see everybody around you is so clumsy and silly and pretending to be cool and having fun. Uh, finally! It's turned on again and you can keep on having the time of your life.
Dying people are so graceful, they move with such a bewitching plastique, they're like ballet dancers. They do not exist, until they die.
I don't know if it's intentional, but it looks like screen tearing, and i don't think I've seen anybody using this artifact as a feature before.
