Used your guide and it is very nice thank you, it really helped.
Just want to point out that some steps are better done early in the game before going to upgrade the staffs, such as...
Upgrading punch to Thunder Gloves
Gaining the Air Strike Grenade
These steps are very challenging to do in high rounds when thunder gloves are no longer one hit kill (round18) and you swarming with hordes, it is easier getting these steps done as early as possible.
Agreed if you wait that long to do the steps....
The Thunder Fists, Quad Rotor, Air Strike Grenade, & Zombie Shield can be worked on before their listed need.
If YOU wait that long then YOU just make this harder and longer then it has to be.
With all do respect, make this easier for noobs and people that doing this for the first time because it is them who will be reading it.
And no, getting staffs is not necessary before attempting to get air strikes, and defiantly not the stupid fists.
Still the best text walkthrough available, your pictures of the codes help SO much. Have had this bookmarked for quite a while now lol.
