Gustavo was born in 2235. Prior to becoming security chief of Tenpenny Tower, Gustavo worked his way up to become leader of a mercenary band of professional fighters. Mister Burke was rescued by Gustavo and his band, and quickly hired him and his men to form the security force at the Tower. Personality: Gruff but good natured in a "Don't give me grief, I'm just doing my job, ma'am" kinda way. However, he soon becomes a no-nonsense hard-ass when his team or his charges are in immediate danger. He is particularly hostile to ghouls. "The only good ghoul is a dead ghoul," he is fond of saying, particularly if ghouls are nearby. If it is pointed out that not all ghouls are mindless killing machines, he responds "It's only a matter of time before they go zombie. Dead now or dead later. Why take the risk? Besides, you're doing them a favor."
Despite having his own locker, he does not have the key to it.
During the Tenpenny Tower quest, he will give the Lone Wanderer an R91 assault rifle and a small amount of ammo, regardless of which side the Lone Wanderer decides to be on.
Occasionally he may give the Lone Wanderer a Chinese assault rifle instead of an R91. This happens more often when the player starts the quest at a higher level with more firepower than somebody usually would when starting the quest for the first time.
Gustavo will take over Tenpenny Tower if Allistair Tenpenny is killed. If he does, he hates the ghouls much more than Tenpenny and the player will need to kill Gustavo for a 'diplomatic' solution on the quest.
"You serious? You don't know what a Ghoul is? A goddamn disaster waiting to happen that's what they are. Sure, maybe you can get over the fact they look like someone took a cheese grater to their face. But it's what you don't see that's the problem. The radiation slowly eats away their brain, then they go zombie on you. It's better for everyone to kill them before all that, if you ask me."
"Your bleeding heart is liable to get you in a lot of trouble one day. Look kid, eventually all Ghouls go zombie on your ass. It's only a matter of time. Kill them when you find them. It's a win-win. You put them out of their misery, and save someone else from getting torn apart."
Playstation 3 If all humans and Chief Gustavo are killed and the ghouls are living in Tenpenny Tower, then the ghoul residents will still comment about Chief Gustavo as if he was still alive. [verified]
Xbox 360 Chief Gustavo has been seen wandering around near Springvale. This was seen after the Megaton bomb was detonated and the ghouls were killed. [verified]
Xbox 360Talon Company mercs will sometimes attack Tenpenny Tower, and if this happens, Chief Gustavo can be killed. This will render the Tenpenny Tower quest unable to be completed even if you kill Roy Phillps and the ghouls in the tunnels. [verified]
