[quote=@Raylah] What is the timeframe here - how long after the fog arrived is this situated? [/quote] The fog appears in 2025 and Philly becomes a city state around 2026. Current year is 2040. [quote=@Raylah] What about more primitive weapons like bows, spears, etc. - would those be useful, or completely outshined by guns? [/quote] Yes, well functioning guns are hard to come by. So mostly people use primitive technology, even medieval things like a crossbow. However, they will make an appearance later on. [quote=@Raylah] The fog comes and goes to places, or is it a permanent thing in some areas? [/quote] Permanent thing everywhere to people's knowledge. [quote=@Raylah] What about normal animals, are there some still left in the wild, or were all killed/mutated by the fog? [/quote] Mostly mutated, not all are hostile though. [quote=@Raylah] Also, I am not from US, and I have a rather rough idea where Seattle and Pennsylvania are located. But according to googlemaps there is over 2600 miles between the two places. I assume the plan isnt the walk the entire distance on foot, so there are some vehicles still operational? [/quote] Vehicle.
