Fallout 3 starting out help?

You need to continue on with the main quest! Disable the megaton bomb as quickly as Possible!! If you have the map packs or just operation anchorage... Do OPERATION ANCHORAGE FAST! It levels you up fast. When you get to GNR make sure you go and help three dog with his quest. When you arrive at Muesum of technology dnt go in yet becuz ull get r@ped. Go to Muesum of History and go into underworld. There is at least 3 side missions that will take you places that will level u up quick. Focus on Small Guns, Speech, Barter, Repair, and medicine. GET TO RIVET CITY also! You will eventually find it when you go more into the main quest( which is important). Thts all I can say and if you need more help then message me on my Xbox live account(if you have one) : I ErnyZz XO.... Or at my email: ernydenise@gmail.com
