Sniper: Elite? The first 4 games go on sale on steam fairly regularly. I played the 5th one with GamePass and I actually really liked that one. The levels are huge and can take you anywhere from thirty minutes to a few hours, however you want to play.

In the 5th one, there are also settings to make it ultra-realistic. I haven’t played with those, but I’ve seen gameplay and it’s almost like a different game.
