A big part of the city has been secured while the infection was spreading in the city. But there is still a big area infected. Infected area has been bordered with walls that zombies can't pass. So all zombies are running through the only road which hasn't been closed by walls yet. Infection mustn't spread out from the city. Defend the road with your team. Don't let any zombie pass the road.
cool!killing zombies all day is a
good time waster.a few hints,try to
make your bullets accurate(that way
your clip wont run out as fast and is
better than wasting your clip
shooting nothing).
2.try shooting the entrance to where
the zombies come from(holds them
back).
and 3.try using the airplane when you
reload
