maybe they just want to torture you with the wait, its not like the gun is an earth shatering weapon that drives the story.
i don't think its would destroy the game to say, tommygun confirmed.
They are masters of suspense that's for sure. It should be in the game. One: it was a common weapon in FO2 and there are two in FO Tactics. Two: It's Vegas in the 1950's mindset. There will be mobsters using the Tommy gun, there are in New Reno. Three: I want to make a mobster character. He dresses in a fine pinstripe suit, fedora, smokes Cigars. Main weapon, Tommy Gun also used Colt .45, baseball bat and brass knuckes. I can't do this without the Tommy Gun or .45 cal ammo.
I don't know if there will be cigars but there should. If no cigars, I can settle for Cigarrets as long as I can smoke them.
