The mod in question is the Closer to Classics - Stronger Bozar mod (found here http://www.nexusmods.com/newvegas/mod.... Put simply, it tries (and succeeds) to make the Bozar live up to its Fallout 2 grandfather, a gun capable of turning several power armored enclave into mince meat in just one turn. All credit goes to rulla, the mod maker. Just wanted to show how to make your Bozar not be a waste of 20 grand, and not disappoint fans of the orignal games (such as myself). Enjoy!
