I'm trying my best with onward (1.7 on Quest via VD). I'm not into multiplayer stuff, but saw the hype and decided it was worth a go even to mess about with the single-player training stuff.
I'm an old git, but even on rookie, the AI of the enemies seems far too razor sharp for me. I peek my head out a tad around the corner of a building and within a second I'm taking damage from 2 or 3 guys that are merely small black outlines from several hundred yards away. Back in, regain a bit of health, back out knowing where there are and they still get off bullseye shots at me before I can get them in my sights. Every one of them seems to be a crack shot. One or two lucky hits from me and they throw out a smoke bomb and move position, and then they'll split up and a couple will flank my position.
More times that enough I end up dead with very little feeling of having had even a bit of a good time. 20 goes I've had, and once..just once.. I killed all seven of them.
And yes, I know I'm old in this realm, but I think not having a crouch button, i.e. actually forcing you to crouch etc, is a killer.
