I got a character to max rank and retired them, which I think counts as 'completing'.

Untouchable atmosphere (barring some graphics tech jank like the UI reflecting in water) and probably the best realisation of "true grit" shooting since Red Orchestra back in The Day. The 1s and 0s behind the realist horror magic can sometimes get exposed as you play more games and end up learning how things really work, but the real meat of this game is in the pants-shitting firefights where anything and everything can happen. Man is the real beast, etc.

Best played with friends, as you can chat away the dead air spent walking between objective markers in the early game. I totally understand why the "walking sim" stuff exists (tension!!!), but I do almost wish there were gametypes that got you into the gunplay sooner. Walking for 15 minutes only to lose 4 hours of character progression to a sniper cosied up in a grain tower feels ROUGH
