BTW, you are a complete n00b if you say that a shotgun is the best choice for Zeds (Zacks, Geeks, Shamblors, walkers, etc...). You need fast reloads, light weight ammo, and maneuverability. Something like a M1.30 carbine, AR-15, 9mm carbine, or heck, even a .22LR. You just need to poke a hole in the skull and scramble the brain.
Things to remember:
- Have backup
- Have a backup for your backup
- Blades don't need reloading
- Have quick release buckles on any gear you are carrying.
- If you are bitten, keep fighting till you fall. Take as many of them with you as you can to help save the rest of your group. Take the fight to the Zeds. Draw them into a free fire zone. Whatever- just don't give up.
