Assassinate Boss Salvatore for Big Jesus Mordino.

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

Walkthrough
Salvatore can be killed in three different ways. The player 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 a poison tank. Thirdly, the player 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.

After cleaning out Salvatore's bar, head back to Big Jesus and accept your reward. You'll get some chips for your troubles, 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.
