Born in 2255, Boone is a town guard and former NCR sharpshooter in the 1st Recon Sniper Battalion, a unit which has a reputation for being the best of the best. He is bitterly whiling away the hours until he can find out who is responsible for the disappearance of his wife, Carla, and kill them. Hardened and psychologically troubled from his time in the NCR military, Boone vacillates between being a stone-cold killer and a decent human being. Venturing out from the relative safety of Novac brings Boone into close contact with his old life until he is forced to deal with the tragic events that caused him to leave the military.
Boone met Carla while on leave on the New Vegas Strip. Carla was the only thing in the world who made him feel calm and happy in life. When he listened to her, she made him forget about everything he did in the military. He left the military, married Carla, and moved to Novac at the invitation of his 1st Recon friend, Manny Vargas. Jeannie May Crawford describes Carla as a "cactus flower": pretty to look at, but hard to get close to. She was never content with the ordinary life of the small town. Carla's attitude toward the town caused distance between Boone and Manny, which continued after Carla's disappearance. She had been kidnapped by the Legion, and Boone suspected she was betrayed by one of the townsfolk.
After completing several quests with Boone as a follower, it is possible to gain more information about Boone's wife. When she was kidnapped, he tracked down the slaving party in hopes of rescuing her, only to find her being auctioned off with hundreds of other slaves to Legion soldiers. All Boone had was his rifle and the distance between them. Instead of subjecting her to the horrors of Legion slavery, he chose to take her life in a mercy killing. As a result of the psychological trauma Boone endured, he has become suicidal; he has no goal, purpose, or desire in life but to slaughter Legionaries (preferably by assisting with cranial perforation) until the Legion finally catches up to him. Boone also reveals he was part of the NCR attack on Bitter Springs, where he and his squad were ordered to shoot members of the Great Khans, including women, children, and the sick.
Craig Boone, despite leaving the military, is still an NCR soldier at heart; he refuses to work with a terrorist against the NCR and will not tolerate the Courier working with Caesar's Legion. In fact, if the player enters the Fort with Boone, all Legion members will become immediately hostile, regardless of the player's previous standing with them.
If you have Boone kill Manny Vargas during One for My Baby and pass a Speech check to convince him that Manny was guilty, he will tell you to "Never say that name again." when asked about Vargas again.
If the player has not yet recruited Boone, he will refuse to speak to the player if their overall NCR reputation is significantly below neutral, or if they have significant positive reputation with Caesar's Legion. The reputation can be temporarily swayed by wearing any NCR armor, allowing the player that faction's relations and reputation. Though ironically Caesar's Legion armor (or any other faction armor) works just as well.
If you get Boone to kill someone who is "responsible" for the death of his wife, he'll later ask you what gave them away. If you respond with "I had a hunch," he'll be hostile towards you and won't talk to you anymore.
If asked if he will ever take off his beret, he will say "No."
If the player takes his beret, Boone says "I would really like my beret back, please." However, not returning it causes no significant results. Oddly enough, he will still say this even if you trade it back to him before closing the inventory window.
If the player enters Boone's hotel room after sending him back to Novac, Boone says "You need to leave." However, staying in the room or stealing items while being noticed by Boone causes no hostility against the player, but you still lose Karma.
If the player travels near Cottonwood Cove or Nelson with Boone, he will mention his grudge against the Legion and the player will be given the option to continue on with him or not.
If you're near the boat in Cottonwood Cove, Boone will say to you that this would "probably be the last boat you take."
After killing Caesar, Boone will say, "Thumbs-down, you son of a bitch!", in reference to the gladiatorial games. He will also talk about the kill next time the player speaks to him.
Tired of waiting for the world to be done with him, Boone ventured into the wastes to make his own way out. Unable to clear his mind of the past, he was at last granted the death he'd awaited, bringing final rest to a life that had ended long ago.
As the Battle of Hoover Dam ended, Boone confirmed what he had always suspected - that revenge would never quiet his troubled mind. Side arm in hand, he journeyed back to California in search of the NCR officer who had led the attack on Bitter Springs. There, with only two bullets loaded, Boone did the only thing he believed would put an end to his suffering.
Looking for a place where he could be of some use, Boone found himself re-enlisting with his old unit. Though his regrets remained in his thoughts, they coalesced into a purpose, and Boone embraced it. He spent his leave time hunting down slavers in the desert, his First Reconberet the last thing they never saw.
Complete Eureka! for the NCR; complete I Forgot to Remember to Forget by convincing Boone to make amends over Bitter Springs.
Though NCR was withdrawing from the region, Boone remained in New Vegas, finding work as a security guard and caravan scout along the highways. While he might've preferred rejoining his old unit, Boone couldn't bring himself to abandon the city where he'd met his wife.
Boone refused to take the Legion's victory lying down. Heading to the hills with his rifle, he began a deadly campaign against high-ranking Legion officers. And though the price on his head rose to levels unheard of, few pursued it, fearing it would be the last thing they'd never see.
No longer held in check by his conscience, Boone found lucrative work as a mercenary and assassin. No job was too violent, no target too innocent. As long as the caps were good, Boone would take the job.
Driven mad by Caesar's victory at Hoover Dam, and unable to escape his memories, Boone staged a suicide mission against the Legate. Fighting as he wished he would've fought on the day of his wife's death, he brought down scores of Legionaries before being caught. Before his crucifixion, he was brought before the Legate, who expressed his admiration for Boone's reckless abandon. Boone spat tobacco in his eye, for all of Caesar's armies to see.
Being 26 years old, Boone is the youngest humanoid companion in New Vegas.
Boone has excellent Guns skill and provides the Spotter perk, while also being deadly with a melee weapon. He is also surprisingly resistant to damage for a non-mutant companion.
Though Boone states that melee isn't his "strong suit," and that he wasn't given much close combat training, Melee Weapons is actually one of his tag skills.
Boone is automatically hostile to any Legion faction members. Legion members are always hostile to Boone, as well as to the Courier while Boone is serving as a companion. This only applies if the Legion can see him, however; if told to wait out of sight, Legion will not turn hostile.
Boone will not talk to the Courier if they are "shunned" or worse by the NCR unless the Courier is wearing NCR gear that turns their apparent reputation to neutral. Once recruited, Boone will follow unless the Courier puts on Legion gear.
Boone will return to Novac after a few days if "lost."
The Kings will say "Is that guy NCR? He looks NCR."
Drunks in Freeside will say "Hey, nice hat there, fancy pants!"
Some NPCs will incorrectly refer to Boone as a Ranger, such as one NCR trooper in the Las Vegas Boulevard Station, who will regard Boone incorrectly as a ranger but also "fine company."
Boone has unique comments for a variety of game locations and situations:
Boone will say "I need a bigger caliber" or "I'm not punching through" if his weapons aren't getting through the enemy's armor DT.
When the Courier shoots while not engaged with a target, he'll say, "Let me aim that for you next time." This comment can occur when attacking a target at long range, even if the Courier hits it, which is ironic, since Boone is supposedly spotting the target.
When entering the REPCONN test site basement with Boone for the first time, he will mention that it's "dark here" and that if you plan on using a weapon with a scope, he was trained as a spotter, and he could help you find your targets.
Mortimer will comment on Boone being in good shape and looking healthy, while insulting Boone as being a little gamey and rugged, when offering to sacrifice him to Mortimer during Beyond the Beef.
For some reason, prolonged swimming or just swimming in Lake Mead while having Boone follow the Courier, will cause him to die after he swims around in circles for a few minutes.
After wiping out the Legion at Cottonwood Cove, Boone will say, "Wish there was more of them, I wasn't done yet."
After you kill Oscar Velasco, Boone will say, "Great Khan looks like. Guess he fought at Bitter Springs, or saw it happen."
Boone will give the Courier one warning before leaving permanently (similar to when Caesar sends Vulpes Inculta to the Strip to wipe your infamy slate clean) if they work with the Legion and gain a positive reputation with them. So if the Courier plans on doing several missions for the Legion, leave Boone in the Lucky 38 presidential suite and speak to him once finished. If you choose to follow the Legion path through the end it will be impossible to take Boone to the battle at Hoover Dam.
Sometimes, when approaching big Legion strongholds, like Cottonwood Cove or Nelson, Boone will tell you that he's going to kill any Legion members in sight.
At the Bitter Springs supply cave visited in Climb Ev'ry Mountain inhabited by the Great Khan, Oscar Velasco, Oscar will attack the Courier after shouting "Die NCR Scum!" if Boone is their companion. The Courier must make Boone wait outside the cave if they do not want to kill Oscar.
If the Courier chooses not to tell The King about the messenger during the quest Kings' Gambit, Boone will sometimes attack the missionaries. The Courier will not lose him as a companion or even get a warning.
"Maybe looking back you'd do things differently, but that's not how it works. In the field, you hesitate, you or someone you care about will die. They teach that from day one. [...] You don't come out of a tour of duty without regrets."
