my sidearm is a sniper, praise the Longhorn, and 308 winchester is everywhere, but you better fire it from a safe place, its loud as hell and single shot, but i killed a bandit at 100 meters ( in the chest) and he dropped dead, so its great.
Evereytime i hear someone say something like "But in that country its very difficult to find firearms", come on guys, what about the police stations, the national army crumbled too, were did all their weapons go? We are talking about a zombie apocalypse, maybe even the government started to give away weapons to the civilians at their last try to save their country.
It would be interesting to see a big rural area with snowy mountains, and small towns all over the map, civilian weaponry would be more common, and maybe people would need to hunt in order to obtain food, vehicles would be important too, it would be interesting to design a high security prison with military loot too.
