no, pedestrians will literally never walk across the street. every time i have shot someone walking across the street, it was an assassin.
They do, its just the assassins will walk across the street towards you VIP. And the knife guys still sometimes just take the sidewalk.
I can't get past the third level where everyone (including you) has sniper rifles
they ambush him with like, 30 people at once!
I also can't aim for stuff with the hunting rifle
Crouch to use the snipers scope.
Also, if you find yourself facing many enemies at once, press E key, shoot, press E key and shoot again. Repeat for however many enemies there are. Just be aware this will NOT work on the zombie assault rifle level.
