I'm gonna be real this game is hella fun through location 1-4 then you have location 5-6 ok it's getting pretty hard... But after that there is no way to beat this without grinding for a long time or pay to win, which the game pushes for alot. Like I got so petty I got a hacked version of the game! And I struggled with locations 7-8 even with unlimited courage & money like zombies have like 1000 HP and hit like trunks. On top of that the game sends like 20 of them at once your way.
