Ok so il write it then ask for help: The year is 2067 and back in 2019 the world got caught into a giant nuclear war and there are very few if any safe zones and you are a young adult/teen who lives in the corruptly run europa land ( the names for places no longer exist anymore so where europa actually is is up for debate anyway) adn for years you have wandered whats going on in the private factory like building, you remember going there as a child for some reson so one day you somehow sneak in and basically realise that its being used to manufacture or restore weapons and WMD's and on your way out you get caught but resist and are now on the run, you manage to steal some doents and realsie you ahve the target list for where the attacks will occur as they seek world domination, so basically you go to warn people of it and try to get a group to prevent it and on the way you battle mutants etc, and yeh any other suggestions would help and i would like to now possibly what countrys would not be involved ia gaint nuclear war and also i want to incorporate maybe some sort of distant creaute like aliens but not as alieny lol.
