OMG Freaking awesome! You are a mastermind!
OMG this was such a fun game and I sadly only survived 19 days. My main plan was at first get as many survivors first. So I had 5 which was a good start for me.
I then used them to fight off the waves of zombies. Only repaiered the wall when it hit 70% or below. I then looked for weapons and eventually managed to get the Chainsaw. That was my main weapon in everyfight ever since I got it.
The Chainsaw was in my opinion the most powerful weapon and most reliable. Keep your men numerous and your wall healthy. Now with all these men and the chainsaw weapon I always only ended up with my wall taking only 5 to 7% damage. Now since you don't get the chainsaw for a while I find the shotgun and saw off work second best as well.
Now the reason I lost was I used a weapon not being the chainsaw. I think I used the last weapon I got. As for how to face the armored zombies, the easiest for me was the chainsaw in the face. No armor there and what easier way to hack up a zombie then to slice and dice his face. Those dogs, their main theat is they distract your friends from the real problem. I suggest removing them when the zombies are not at the wall.
The fat ones are the second toughest for me. Chainsaw works perfect yeah but I'd also have to say Shotgun is secondary good.
Well that's all the tips I got for the young zombie hunters. Live long, die well as they say.
