I've been playin Fallout 3(BEST GAME EVA) for a while now and have ammased quite a collection of special items such as the Xaunglong assault rifle, Jack the ripper, Alien blaster, Vengance, T51B power armour and my prized possesion THE EXPERIMENTAL MIRV and many more stuff.
If you have just read this and would like to know the location of ANY of the special items feel free to ask.
