This game has a high difficulty curve, but once you get the hang of it, you'll be killing zombies nonstop.

The first character you will get to play will be the policeman Jon. He was tasked with the destruction of the zombie apocalypse.
Jon starts at level 1 with no upgrades and no special abilities, this makes him the hardest character in the game.



You can use dynamite when you're surrounded by enemies. One dynamite will destroy every low level zombie on the screen. Every detonated enemy will drop money.
You can either find dynamite or buy it before the start of the level.

You will die over and over again - that's intended.
Try to collect money when playing and upgrade your characters!
To keep things interesting zombies are stronger than you, and will continue to grow stronger.



Try not to waste money by buying items in the game map. Upgrading Jon in the beginning will help you much more then buying items.
Zombies drop more money in later levels.

You can level up your characters in "Upgrade Stats" menu

Your first milestone should be saving up enough money for buying Cloe



Cloe has the ability to pull all dropped items to her.
Now that you don't have to worry about dropped items, you can focus on avoiding enemy attacks better.



Now it's time to also max out Cloe's level.

If you have a lot of money you should buy MK1000 and upgrade it atleast to level 5.
With this weapon you should easily reach atleast Stage 4 of 6 in arcade mode.



Good Luck
