Zombie Battlefield

The zombie apocalypse is now upon us and it looks like men are losing.  Now, the zombies are attacking the final outpost to consume the human's living there.  Fortunately, the wall is thick and would not give in easily.  But, that  doesn't mean that it won't.  It has to go sometimes.   The game is played via mouse and the idea here is to kill all the zombies before it reaches the wall. You will earn money after every level.  You can use it to buy weapons, hire defenders or repair the wall. It is all up to you to last as long as you can.
