please read my guide this is my way of winning each levels. this guide will be able to help you get money at early stage and all the weapons quickly. enjoy!(yes i know it sucks but thats how i play and i wanted to share) 1. first get the ninja less money more better in melee (important) 2. in the first stage, try to rack up money by staying near the end of the level and wait for the zombies to come. 3. after getting 650, get a sledge hammer. 4. at level 4, breeze by if you got hurt a lot and use the money to buy healing pack, if not, try to rack around 550. 5. next level, rack about another 550 money. dont buy any guns, only the melee, buy the katana 6. as you kill, you should see that you are killing the zombies with one or 2 hits with the katana. get 350 for the shotgun 7. dont waste your bullets on the shotgun but save it, abuse your pistol until no more bullets while slicing the zombies with your katana 8. max upgrade your shotgun 9. get the beginning of the submachine gun, then soon get the chainsaw. 10. upgrade to flamethrower 11. get upgrades for the submachine gun to a gatling gun or the max. 12. use your machine gun's on regular zombies, katana and shotgun on the red eyes and flame thrower and katana on white pale dudes 13. upgrade the bazooka to the high tech 14. use on red eyes 15. upgrade everything else
horrible strategy!!! i use the clown to rack up money for the big guns and im doing fine til now (level 21)
best is level 41 with zombieville guy. All you do is upgrade pistol and use till round 10 then use machine gun or shotgun till 25. Then use the lazer until you run out then survive on rocketlauncher
