Obsidian built New Vegas in about eighteen months on Fallout 3's engine, and it is still the reference point for reactive RPG writing. You play a courier shot in the head over a package, then decide whether the Mojave belongs to the NCR, Caesar's Legion, Mr. House or nobody at all. Thirteen skills, a perk on every even level, and a cap of 50 once all four story DLCs are installed.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
SPECIAL and skill points
Seven attributes set your baseline and gate perks, and Intelligence directly controls skill points because each level grants 10 plus half your Intelligence. Implants bought at the New Vegas Medical Clinic raise attributes later, but the number you can install is capped by Endurance.
Perks every two levels
Unlike Fallout 3, New Vegas hands out a perk on even levels only, so a level 50 character with all DLC picks roughly 25 of them. Traits are chosen at creation and always pair a benefit with a real downside.
Faction reputation
The NCR, the Legion, Mr. House and every smaller group track fame and infamy separately, and both can be high at once. Wearing a faction's armour changes how third parties react, which is the standard way to walk into a hostile camp without a fight.
V.A.T.S. and weapon condition
V.A.T.S. spends action points on queued shots at limbs, weapons or heads, and critical chance scales with Luck and the Better Criticals perk. Every weapon degrades with use and loses damage, repaired with duplicates or, at Repair 90, with anything in the same class via Jury Rigging.
Hardcore mode
Hardcore adds weight to ammunition, forces food, water and sleep, makes stimpaks heal over time instead of instantly, and makes companion deaths permanent. It is a toggle rather than a difficulty setting, but the achievement requires running it from level one to the end of the main quest.
For a deeper dive into how these systems interact, see our Fallout: New Vegas combat guide.
Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Cowboy gunslinger | S | Open in V.A.T.S. with head shots, reload behind cover, and let Cowboy plus Better Criticals do the arithmetic. Dynamite handles anything armoured. | Agility and Luck first, then Perception, with Guns pushed to 100 early |
| Energy weapons specialist | A | Take Laser Commander and Meltdown, aim for heads in V.A.T.S., and recycle drained cells at a workbench so ammunition never runs dry. | Energy Weapons to 100, Science high for Meltdown and Vigilant Recycler |
| Unarmed brawler | A | Take Piercing Strike to cut through damage threshold, then Super Slam and Paralyzing Palm to lock enemies down. Learn Ranger Takedown from Ranger Andy in Novac as soon as you arrive. | Strength 7 or higher, Endurance for implants, Unarmed and Melee to 100 |
| Sneak sniper | A | Break line of sight after every shot so enemies search the wrong position, and keep Ratslayer for anything that closes distance quietly. | Agility and Perception, Luck for criticals, Sneak and Guns to 100 |
| Speech and Barter diplomat | B | Talk through the Strip's factions, chew Party Time Mentats for checks you narrowly miss, and let Boone or Rex handle whatever turns into a gunfight. | Charisma and Intelligence at creation, Speech and Barter to 100 before anything else |
Cowboy gunslinger (S-Tier): Revolvers, lever-action rifles, dynamite and knives, all boosted 25 percent by the Cowboy perk from level 8. It is the highest damage per cap build in the base game and it fits the setting exactly.
Energy weapons specialist (A-Tier): Lasers and plasma trade ammunition scarcity for extreme damage against armour. The Silver Rush in Freeside and the Van Graffs are the only reliable suppliers until Old World Blues opens up.
Unarmed brawler (A-Tier): Unarmed scales through a dedicated perk chain plus special moves taught by trainers around the Mojave. It costs no ammunition at all, which makes it the strongest Hardcore mode build by a wide margin.
Sneak sniper (A-Tier): Sneak attack criticals multiply damage, and the Anti-Materiel Rifle plus a suppressed backup clears most encounters before they begin. Fragile in the open, so positioning matters more than gear.
Speech and Barter diplomat (B-Tier): New Vegas resolves more quests through dialogue than through combat, and a Speech of 100 opens paths no build can shoot its way into. Weak in a firefight, so it leans on a companion who is not.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| That Gun | A . | Levels 5 to 20, and any run that wants real damage before the Strip opens up. |
| Anti-Materiel Rifle | A . | Clearing Quarry Junction, Deathclaw promontory and any sniper build past level 20. |
| This Machine | A . | Mid to late Guns builds that want single-target damage without a bolt-action's reload downtime. |
| Ratslayer | A unique varmint rifle in Broc Flower Cave that arrives with a night vision scope, a silencer and a much faster reload than the base weapon. | Early stealth builds. It is reachable at level one if you can survive the trip to Broc Flower Cave. |
| Ballistic Fist | A shotgun bolted to a power fist and the top-end Unarmed weapon in the base game. | Unarmed builds from the mid game onward. Two-Step Goodbye from Gun Runners' Arsenal is the unique version. |
That Gun: A .223 revolver sold by Cliff Briscoe in the Dino Bite gift shop in Novac, and one of the best early purchases in the game. It fires 5.56mm rounds at high damage with only a modest Guns requirement.
Anti-Materiel Rifle: A .50 MG bolt action that deletes almost anything in one aimed shot, Deathclaws included with the right ammunition. Rounds are heavy and expensive, which makes it a genuine logistics decision in Hardcore mode.
This Machine: A .308 semi-automatic rifle, an M1 Garand in all but name, handed over for the Dealing with Contreras quest at Camp McCarran. High damage per shot with a fast follow-up and no scope to fuss with.
Ratslayer: A unique varmint rifle in Broc Flower Cave that arrives with a night vision scope, a silencer and a much faster reload than the base weapon. It eats cheap 5.56mm ammunition.
Ballistic Fist: A shotgun bolted to a power fist and the top-end Unarmed weapon in the base game. Backed by Piercing Strike and the unarmed perk chain it kills most humanoids in one or two hits.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Goodsprings | Levels 1 to 4 | Varmint rifle, Sunny Smiles' hunting lesson, first faction reputation choice |
| Primm | Levels 3 to 7 | ED-E, Vance's 9mm SMG, the sheriff decision |
| Novac | Levels 6 to 12 | Boone as a companion, That Gun, the Come Fly With Me quest |
| Freeside | Levels 8 to 16 | Arcade Gannon, Silver Rush energy weapons, Strip entry |
| Hoover Dam | Level 20 and above | Faction ending, endgame equipment, the last point of no return |
Goodsprings: Where Doc Mitchell digs you out of a shallow grave. The cemetery, the schoolhouse and the Ghost Town Gunfight quest teach the reputation system before you meet anyone who matters.
Primm: A raider-occupied town on the road east, built around the Vikki and Vance casino and an argument about who should be sheriff. The NCR Correctional Facility sits just north and ED-E is repaired here.
Novac: A motel built around a dinosaur, with Boone standing in the dinosaur's mouth at night and Cliff Briscoe selling That Gun below. REPCONN is west and the Legion problem at Nelson is east.
Freeside: The lawless district outside the Strip, run by the Kings and the Van Graffs and policed by nobody. The Old Mormon Fort holds the Followers of the Apocalypse and the Silver Rush sells energy weapons found almost nowhere else.
Hoover Dam: The strategic prize the whole game argues about, garrisoned by the NCR and coveted by the Legion. Every faction decision you made resolves here in the final battle.

Tips That Actually Matter
- Intelligence controls skill points at 10 plus half your Intelligence per level, so the gap between Intelligence 4 and Intelligence 8 is roughly a hundred skill points over a full run. Take it high at creation or buy the implant early.
- The road north out of Goodsprings through Quarry Junction is guarded by Deathclaws that kill any low-level character instantly. The intended first route is south through Primm, Nipton and Novac, which is why the game keeps pointing you at Novac.
- Reputation tracks fame and infamy separately per faction, so you can be liked and hated by the NCR at the same time. Faction armour overrides how patrols react, which lets you walk into Cottonwood Cove or Camp McCarran unopposed.
- Jury Rigging at Repair 90 repairs any weapon with any weapon of the same class. It turns junk pistols into repair kits for That Gun and makes the caps economy trivial from the mid game onward.
- Skill books are permanent and Comprehension raises each one from three points to four. Take Comprehension before you read anything, then buy books from Mick and Ralph and the Gun Runners rather than hoarding caps.
- Speech checks in New Vegas are hard thresholds, not dice rolls. A Speech of 75 opens a large slice of quest resolutions, and Old World Blues skill implants can push you over a specific number when a check blocks progress.
- Implants at the New Vegas Medical Clinic cost 4,000 caps each and you can install a number equal to your Endurance. Buy the Endurance implant first if you plan on several, because raising Endurance later does not retroactively widen the limit.
- Damage threshold subtracts flat damage per shot, which is why a fast weak weapon does nothing to armoured targets. Against NCR Rangers and Legion veterans, switch to armour-piercing ammunition or a high-damage single-shot weapon instead of emptying an SMG.
- Every permanent companion grants a passive perk on top of the combat help. Boone's Spotter marks hostiles at long range, ED-E's Enhanced Sensors extends your own detection radius, and Raul's Regular Maintenance slows weapon and armour decay.
- Hardcore mode's real cost is ammunition weight, not hunger. Plan around a primary and a backup that share ammunition types, and use the reloading bench to convert scrap cases into the rounds you actually fire.
Common Mistakes to Avoid
- Heading north out of Goodsprings toward Quarry Junction at level 3 and meeting a Deathclaw pack the game never warned you about in plain language.
- Dumping Intelligence at character creation. It is the one attribute that compounds, and low Intelligence quietly costs a hundred skill points and a stack of dialogue options.
- Spreading points across all thirteen skills instead of pushing Guns or Energy Weapons plus one social skill to 75 or 100. New Vegas gates content on specific thresholds, not on averages.
- Selling duplicate weapons before taking Jury Rigging. Those duplicates become the cheapest repair material in the game the moment Repair hits 90.
- Committing to a faction ending before finishing side content. Siding with the NCR or the Legion locks out quests and turns companions hostile on sight.
Frequently Asked Questions
What is the level cap?
30 in the base game. Each of the four story DLCs raises it by five, so Dead Money, Honest Hearts, Old World Blues and Lonesome Road together take you to 50.
Do I need to play Fallout 3 first?
No. New Vegas is set on the other side of the continent with different factions and no shared characters. The only carryover is the engine and the mechanics built on it.
Which ending is the best one?
There is no canonical answer. The NCR brings bureaucracy and overextension, the Legion brings order through brutality, Mr. House brings a technocratic Vegas, and Yes Man makes the Courier the authority. Each produces a different set of Mojave epilogues.
Should I turn on Hardcore mode?
Not on a first run. It adds ammunition weight, food, water and sleep needs, slow stimpaks and permanent companion death. The achievement requires running it from level one to the end of the main quest, so treat it as a second playthrough goal.
Is the PC version stable today?
The base game runs on a 32-bit engine and crashes under load. The community standard is a script extender, a memory patch and the unofficial bug fix pack before starting, which most current setup lists bundle into about fifteen minutes of work.
