Survive the waves of zombies by defeating them with towers. There are 6 different towers and 3 can be upgraded to make them even more powerful. Technic was used to apply spawners but does not require technic to play. There is a lot of redstone and it can also get jumbled up by mobs if they spawn on it. I did my best to prevent them though. It is now updated so that you spawn with money (levers)
