TONS of people. Some have even made it to round 99. Round 20 is NOTHING, no big deal at all.
black ops clealy! those zombies take u down in 2 wakes but left 4 dead zombies take forever
Nothing special happens. The zombies at this point will take massive amounts of ammunition to fell and your console may start slowing down because of the sheer amount of zombies on the screen.
only about 3 days if you play black ops zombies :D trolololololololol LOVE FROM Raksasa Biskit
Ask him politely
It really depends on how long it will take to kill each one.
Not very long; probably under a minute.
Play it at lot, learn how to stay alive when you have a whole level of zombies chasing you, expect the expected and unexpected. Take advice, don't ignore it.
A long time
i farted
yes it has zombies the maps are called house facility temple and overlook it is significantly harder than the main console versions due to no wonder weapons and zombies kill in one hit and take longer to kill
a long time
