Sanitize is just plain awful in every sense. Tactically it makes no sense, but also, get this... I was wandering around the town trying to find one last friggin enemy soldier to get the objective done (which is wrong on its own, if intel knew there was one guy left, they would give you an exact count) but anyway, there I was walking around and suddenly 2 metres in front of me spawned about 15 enemy soldiers in a big bunch. Luckily I had my rifle on full-auto at the time so I managed to mow-down half of them before they butchered me.
I uninstalled the game after this. I will now wait for a mega-patch until i bother again.
