Fallout New Vegas: Fun Findings - Possible Spoiler

Few things I've found are:

Pushy - awesome unarmed weapon. Can be found west of new vegas going up toward the camp where all of the Mutants/Nightkin have their fort. It's located in a mine with mirelock kings (forgot their name in this game). Also in this cave is a bunch of water, swim in it and you'll see a dead mutant with a ton of good items on him.

Silver Rush - Two little tricks. First is, get a stealthboy and jack all of the stuff in the store. Easy 2-3k gold. Another tip is, if you want to kill them but don't want to have to do it later with Casidy, simply let the last guy in the building when you're supposed to be on guard duty. He blows up shop and everyone in it dies.

You can get a special automatic 9mm machine gun from Butch Casidey (or something liek that) in a house that's north, northwest of new vegas. It's a shack and you have to pass a speach check or be able to pick a hard lock.

Pushy and the gold/weapons from silver rush make hardcore playthrough a lot easier. Also, Boone rocks but not best choice if you want to play evil since he gets mad when you kill NCR. Apparently there are also special unarmed moves that you can learn to make you better at fighting. I'm going to get the Novac one tonight.
