I think mine is the sniper rifle.

But I've heard you can get hold of an alien laser pistol that is out of this world (please excuse the pun)

Yeah, you can get laser pistols and laser rifles. They're really good, and probably my favorite weapons in the game. Enemies just disintegrate, or get sliced in half - it's good stuff!

Are you talking about the Fallout 3 weapons or weapons in general?

If you mean Fallout 3 then cant answer (Havent saw any footage)

I like that Heavy Weapon Laser Cannon thing.  I only got it once and died before I got to save it, but it was awesome.  My heavy weapons skill was low, so I was missing a lot, but when I hit, it blew my enemies clean in two!  You can't beat that.

What's the nuke launcher called again?

Dude this is the Fallout 1 forum stay on topic here. Fallout 1 weapons only.

I have a personal love for the flame thrower, even if it means you often can't raid the bodies.....

:/

I have a great love for the Gunblade from Final Fantasy VIII.

You can't loot burnt bodies? I can't recall ever having that problem. The plasma rifle (which in it's upgraded form is the most powerful weapon in Fallout 1) both burns and melts its victims but does not render them unlootable. But I must confess I mostly stay away from the extremely cumbersome, although cool (well...), flame thrower. A good burst from the minigun is my personal favorite.

Yeah, people just see the "favorite weapon" on the main board and dont even look at what forum it's for.

Anyways, brass knuckles!

I always liked the minigun.  You could get people doing the machine gun dance and I think you could also cut 'em in half with it.

The scalpel was my favorite in Planescape: Torment.  For Fallout I side with the Mauser because you keep it around in case you find ammo for it besides the bullets Gizmo fails to fire, but you never do.

223. Pistol or maybe the turbo plasma rifle. :D
