Ultrajet

Ultrajet is a stronger version of the drug Jet.

Locations
A ghoul named Murphy will sell you one Ultrajet for every 8 to 10 boxes of Sugar Bombs. He says he has two of the three ingredients needed to make it. The last ingredient is Sugar Bombs. He will pay you 15 caps for each box of Sugar Bombs that you bring him, and an extra 15 caps (30 caps per box) with persuasion.

Murphy and his bodyguard are located in Northwest Seneca Station.

Ultrajet may be a combination of Jet, Sugar Bombs, and Abraxo Cleaner, since the third ingredient is lying around Murphy's lab in abundance, though this is unsupported. (it seems that Murphy also uses Whiskey since he will use a whiskey bottle while "doing" the ultrajet so it could be made from sugar bombs,abraxo cleaner and whiskey then he adds it to the normal jet (needs to be verified.)

Appearances
Ultrajet appears in Fallout 3.
