i think to kill a flying zombie u need a air gun ;)
Game has good graphics no glitches. just simple kill'em all.
zombies are mindless or "Brain Dead" so who decides boss zombie. this way is better, just an end boss who throws bottles "mindlessly". that is it.
So.
Bring it on....
U take the sword of legacy and heat it in sun till its lava hot then u hit the dragon with it and thats how u kill the final boss
(+ if u like it , Keep it alive)
