What would you rather try and survive in? Think of it as it's just happened in the matter of 3-7 days.

Demon run world - "What he means is Old Testament, Mr. Mayor, real wrath-of-God type stuff!" - Ray Stanz

Demons have taken over the world, having won the battle between heaven and hell. From the fallen angels there are various forms of weaponry. Guns, swords, shields, slight magical items (mainly for detecting demons). You somehow managed to be overlooked as they passed through your area. If not within 30 miles of a 'major' city, there is nobody else around you, the closer to the center of cities the higher chance to find someone.


Nuclear wasteland - Yes, fallout style but with current day weaponry, lets pretend that the contamination dissipates quickly. Still tainting water/food but not in the air so you can walk around. Opposite applies to survivors, closer to the city the less chance of finding others.


Aliens ravaging the world - Fallen Skies or Mars Attacks! would be my best references. A violent alien species have landed, tearing us apart as soon as they arrived. They have set up 'forts' in major cities, flying vehicles doing patrols around the out side of them.


Frozen wastland - comet/meteor passes close to earth, messing with our climate. Everything is now fairly frozen, tall buildings, lakes/rivers (not seas but glaciers everywhere). Days never get warmer than low 40's during the summer months.


Endless desert - same as above only raising temperature. 90 being the low in the winter months.


Jungle citys - Mother nature had decided to take her planet back. Every form of plant in the ground grows rapidly, tearing through skyscrapers and other buildings. Roads demolished by tree roots and oversized grass, rivers breaking dams, valleys and canyons opening and of course all volcano's erupting.
