HELP KELY MİSİON İS HARD

i have finished all the task/quest in the game.But i still feel unsatisfied.the city was so big but the game only let's you travel up to 8 locations.but still i loved the game.it's like the fallout mixed up with left 4 dead but using last stand's engine.

Can someone please tell me how to get brawn before brain. I tried with 1luck 4security and got 8% chance to open it, but the lock broke and i didn't get the achievement. How to do it?

I've beat both game modes, and this is a good guide. Beat the game without any guide, though.
Here are some frendly weapon tips-
A- Survivors
You get that awesome weapon, the RPG, and yet, you only get 5 shots?
What?
NO FAIR!
(It is fair)
Whenever you have a weapon that you don't have enough ammo for, give it to your survivor. They have infinite ammo. So, yeah.
That.

B- Guns, Guns, Guns... and ammo.
The early stages, you don't shoot at all.
Melee will take care of your needs. But...
When choosing a weapon, look at it, and prioritize. Make sure you have enough ammo for a weapon first, and is it better than your current one? MAKE SURE YOU HAVE ENOUGH AMMO.

C- AMMO.
If you don't have the Ammo, forget it. Without ammo, yer screwed. That being said, if you're looking for a lasting gun, look at the SMGs. Most fire fast enough, have accuracy, and do damage to the point where you can rip through zombies. PLUS- They use 45. or 9mm, which is the 2 most common ammo drops and finds. (I found the Kris S/V. Luckily, the military version dropped from a zombie. **** YEAH!

At all.
