Assassinate Boss Salvatore for Big Jesus Mordino

Assassinate Boss Salvatore for Big Jesus Mordino is a side quest in Fallout 2.

Detailed walkthrough
Salvatore can be murdered in three different ways. The Chosen One can use a super stimpak on him, resulting in a heart attack. The other way is by stealing the oxygen tank that Salvatore's breathing is reliant on, and optionally replace it with the poison tank found in the Desperado Basement. Thirdly, they can simply attack him, having to deal with his bodyguards and employees. You'll need to be careful if you're taking the third option; Mason and all of Salvatore's men are armed with Wattz 1000 laser pistols, and the bartender has a shotgun.

Using the Poison tank is the only "silent" kill option (apparently, the poison tank's appearance has them fooled, and they cannot pin the boss' death on you). All others make Salvatore's men hostile upon his death.

If you stop to watch Salvatore die before you leave, you get -5 to New Reno reputation for the evil pleasure.

After cleaning out Salvatore's bar, head back to Big Jesus and accept your reward. You'll get some chips for your trouble unless you've got Charisma 6, in which case Big Jesus will offer you a loaded SMG and a suit of MKII leather armor. Remember to thank him, and he'll also make you a made man of the Mordinos. If you don't thank him, you can still get in with CH 9.

Note that this quest is not available if you've killed Boss Salvatore prior to finishing Big Jesus' other quests.

Mordino's made man
If you complete this task you can become their made man, which however prevents you from completing other families' tasks. If you want to end this last task without becoming their made man, talk to Big Jesus while sneaking. This will not trigger combat but will check the task as done. Alternatively, accept and return later to kill Big Jesus (and his men) when ready.

Bugs
While the idea is to steal Salvatore's oxygen tank and replace it with Poison tank, the script erroneously checks the player's inventory instead of the mob boss' for the Poison Tank after snatching the normal one from him to trigger the assassination sequence. To summarize, you have to steal the Oxygen Tank while also having the Poison Tank in your inventory.
