Zombie TD UpriseAuthor : Positech Games - 20 040 plays
The manual to survive a zombie attack clearly states that the strategy to adopt in the event of an invasion is to burn them, electrocute them, freeze them, shoot at them, etc. So, in a nutshell, ruthlessly annihilate them! Do exactly that by using your complete arsenal of defence towers and placing them in strategic locations along the route to stop the vermin passing. Eliminate zombies to earn money and then buy new towers or upgrade your existing ones.
