This short guide is just to list all guns and turrets and how to unlock them while playing. I made this guide because during a game, it's never the good time to sit and read the in-game descriptions to remember which turret is doing what. And it seems like no website yet lists them all.

Turrets are built in the "build mode" that you can access pushing the B button during a game.
To unlock turrets, all you need to do is to collect scrap metals on the ground until you have enough of them to pay the cost of desired turrets.

You start with a basic pistol. To unlock new weapons, you have to fill completely the bar at bottom of the screen.






When you reach 100%, the next weapon(s) on the tree will unlock. Do this process with new weapons to progress further in the tree.
The last weapons of the tree don't need to have their bar charged because there is nothing else to unlock. However, you'll notice there are random numbers that could appear in the bar. It's a bug of the game.
The bar charge doesn't affect the power of the weapon. It's only required to unlock new weapons.
You can access the gun tree by pushing the button I during a game.

















The 2 bonus weapons marked with a "???" are unlocked after killing over 9000 zombies during a game.

That's pretty much of it. If I play some more of this game, i'll try to update the gun names and try to find out their damage (aswell as updating missing tower damage).

Cheers, happy zombies hunting!
