http://www.pathguy.com/d20modern.htmStarting level is three, no need for Ammo. it's in the internet... so I'm assuming you can find any equipment WITHIN REASON. Put it on your sheet if I think it's too much I'll ask you to kindly remove it. Basic whats happening for those of you who want to make a whole bio and whatnot.
I made some modifications to the xkcd version of the map to suit my DnD universe. Now you are all currently either in, or headed to the capital city of Facebook, Zuckerberg.
What your character is doing there is up for you to decide, but in case you need some inspiration here are some notable events taking place in the city that you could be there for. The biggest and most broad in terms of diverse attraction is the fifth anniversary of the end of the fabled War of '24 in which Facebook pushed Myspace back behind the Elmuth mountains, into the wastes. There is a wedding between one Mary Gritsch and her groom Joseph Greer. Zuckerberg is the most intellectually advanced city on the planet, so you could be here to study. Again just suggestions if you're having a bit of a mental block.
EDIT: Character sheets go here just in case you were wondering.
