who is the guy with the gas mask and revolver on all posters and on the game case?
bottle caps like fo3 or cash money? seeing as this game seems to have alot more civilization than fo3.
i read somthing about making your own ammo? whats actually going on with that? and can i customize my weapons?

The money comes in three different types, depending on the Faction.

The NCR uses NCR dollars.

Caesar's Legion uses Legion Money

Everyone else uses Caps.

If you just search on the forum, you can find alot more information about crafting your own ammo and customizing weapons.

and come on, its pretty obvious who the guy on the covers is.

well not really because the guy on fo3 just looked like a random brotherhood guy in power armor and laser rifle so you know

The guy on the cover is a random NCR soldier, not a specific character.
