So I wanted to make a list of a bunch of the new things in Dead Money unlocked for use back in the Mojave! Just so you know, collecting vendor codes is highly suggested due to there being a vending machine back in the Mojave. Another very important item to collect is cloud residue. Anyway, I'm also rather curious as to what I missed. So telling me what I missed is greatly appreciated.

Well thats it. Tell me what I missed!

Where did you get the slugs recipe and the 308 code ?

The .308 code was in the Villa I believe.. The slugs recipe I got from talking to Christine when she was near the fountain.

I got the coin operator and was able to mkae coins, no slugs though.

It isn't ammo. Basically they're forged Casino Madre chips.

Oh in that case got it.
Still need to find the 308 though.

I totally missed the super heated cosmic knife, cosmic knife spear, and knife spear recipes.

Never came across the Assault Rifle mod either. Boo.

I now I'm missing two of the Holorifle mods... anyone know where to find the other two for when I do it with my EW character?

Thewre is only the cosmic knife spear recipe and heated, and cosmic knife spear is already unlocked.

Randomly looking around the Wiki and look what I found. This will help you alot! http://fallout.wikia.com/wiki/Sierra_Madre_Vending_Machine_Codes
