Pretty cool video!
Personally, I like playing solo. I'm not much of a multiplayer type of guy. I don't find guns to be particularly useful at all. The zombie drawing effect coupled with the small amount of ammo makes me skip collecting guns and ammo in the post zombie apocalypse world.....BUT I do get tired of killing zombies with a bat/crowbar. I long for a varied zombie killing experience. Enter the silencer! http://www.wikihow.com/Make-a-Suppressor
That was just the first link I found. There are hundreds of tutorials on how to turn boom-sticks into quiet-sticks, so I think the silencer would fit quiet well into the crafting aspect of the game. Let me preempt someone saying "there is mod for that. mod your game and leave mine alone", I have seen those mods.
The vanilla game should be modified in some way because it isn't balanced when it comes to firearms. Because of the rarity of ammo, the amount of skill need to actually be effective with a gun, and the massive crowd of zombies you get when firing a gun, guns are more of a novelty than a balanced choice when it comes to playing a character. I want guns to be part of the story of how I died, instead of just wistfully thinking they could play a role.
