for the people who say it goes through the line,does it bother u read the tips:
-The ball can travel up through the line but not down so feel free to jump through it.
i noticed that many are noobs here is hint to win both normal and hard:first start with getting 50$ and buy shotgun then 450$ to get the assault rifle then upgrade barricades two times then get money for last wep then max out your barricades that way normal zombies will die without touching them and that way u can have alot of money then u just take a place to cover your self for last waves with sentry all over the place and mines outside it and watch for the white dots on the map after wave 15 they destroys your barricades and u cant biuld them anymore.keep this live cuz it works and noobs dont whine this was made by lorddeadman
