heres some tips for those people who just bought this game.
1.it doesnt matter how many turrets you have, its better if you upgrade them:)
2.one of the most important things is that the zombies will follow you as long as there not attacking the shack, so lead them towards your weapons.(sometimes it glitches and doesnt work)
3.dont randomly place turrets put then in a way that all the zombies have to pass then and get DESTROYED!!!
Hope that helped:)
