24 weapons in The Last of Us Part I.
2x4
The 2x4 is a plank of lumber and the most common melee weapon in the game, especially in Boston and Pittsburgh. It reaches farther than your fists, stuns a human with one hit and lasts four swings before it breaks.
9mm pistol
The 9mm pistol is Joel's first gun in The Last of Us Part I, picked up from his and Tess's hideout in The Quarantine Zone before they go after Robert. It fires fast, has the most ammo around and stays useful all game as a cheap backup to your heavier guns.
Assault rifle
The assault rifle is the only fully automatic gun you can use in the campaign, and you can only pick one up in the final chapter, The Firefly Lab. FEDRA soldiers carry it in Boston, but you can't take theirs.
Baseball bat
The baseball bat is a blunt weapon that swings faster than the pipe or 2x4 and lasts six hits. The first one sits on top of a washing machine in the laundromat in Bill's Town.
Bolt-action rifle
The bolt-action rifle, also called the hunting rifle, is Joel's long-range gun, taken from a dead Firefly on the second floor of the Capitol building in The Outskirts. Its armor piercing upgrade makes it one of your best answers to armored soldiers and bloaters.
Bottle
Empty bottles work like bricks: throw one to make noise and draw enemies, or hit someone with it to stun them. A bottle breaks after one hit.
Bow
The bow is the quiet long gun. Joel finds it at an abandoned camp in Lincoln during Bill's Town, and its arrows can often be pulled back out of bodies, which makes it a stealth tool and an ammo saver.
Brick
Bricks are throwables you pick up from the ground to distract or stun enemies. Throw one to the side to pull a patrol away, or straight at someone to stagger them for a follow-up hit.
El Diablo
El Diablo is a scoped, high-caliber revolver and one of the strongest guns in the game, able to drop a bloater in two shots once upgraded. You find it in Tommy's Dam, on a body by the first abandoned car before the hydroelectric plant.
Ellie's pistol
Ellie's pistol is the handgun Joel hands her in Pittsburgh, taken from a dead hunter after the plaza fight, with the warning that it is for emergencies only. You control it yourself when you play as Ellie in Lakeside Resort, and she carries it through Left Behind.
Flamethrower
The flamethrower is a homemade weapon, a propane tank with a bike brake for a trigger, found in a loading dock at the University of Eastern Colorado in The University. It is the strongest tool against groups of infected and bloaters, at the cost of short range.
Hatchet
The hatchet is a one-handed camp axe that kills any enemy except a bloater in one hit. It is the last bladed weapon you find, first turning up just after you leave Ish's abandoned settlement in the Pittsburgh sewers during The Suburbs.
Lead pipe
The lead pipe is the toughest breakable melee weapon in the game, lasting nine hits. Joel can first pick one up in The Outskirts while clearing infected on his own, and another lies where Ellie drops it after hitting Bill in Lincoln.
Machete
The machete kills in one hit and swings faster than the hatchet, but breaks after three uses. The first one is in Ish's settlement in the Pittsburgh sewers during The Suburbs.
Military sniper
The military sniper is a tripod-mounted bolt-action rifle you only use once, in The Suburbs. A hunter uses it to pin Joel, Ellie, Henry and Sam down in the street; once Joel reaches the house and kills him, you man the rifle to cover the others.
Molotov cocktail
The Molotov cocktail is a crafted firebomb made from alcohol and a rag, the same ingredients as a health kit. One hit kills almost any enemy outright, and the pool of fire it leaves kills anyone who walks through it.
Nail bomb
The nail bomb is a crafted proximity mine made from a blade and an explosive. Bill gives Joel his first one inside St. Paul's church in Bill's Town, and after that you can craft your own.
Pump shotgun
The pump shotgun is Joel's close-range long gun, handed to him by Bill in the cellar of his church during Bill's Town. It kills most humans and infected in one blast up close, but loses power fast with distance and reloads one shell at a time.
Revolver
The revolver hits harder than the 9mm but fires slower, and it is the pistol Joel draws in scripted scenes. You pick it up in The Outskirts from a dead soldier in downtown Boston, next to his field ops log.
Shiv
The shiv is a crafted blade made from one binding and one blade. It is your silent kill for clickers, the only way to open shiv doors, and with Shiv Master your escape when a clicker grabs you.
Shorty
The Shorty is a one-handed sawed-off shotgun that sits in your pistol slot. You find it in the Pittsburgh sewers during The Suburbs, on a bench to the left just after you set off the first sound trap.
Smoke bomb
The smoke bomb is a crafted sack of sugar and explosive that blinds and stuns enemies instead of hurting them. You first come across it in Pittsburgh, and it is your best escape tool when a fight goes wrong.
Switchblade
The switchblade is Ellie's knife and her only melee weapon. It never breaks, handles her stealth kills and takes the place of Joel's shivs whenever you play as Ellie, including all of Left Behind.
Watergun
The watergun is a toy Ellie and Riley use for a water fight in the Left Behind chapter Fun and Games. Riley stole their confiscated pair back as a surprise, and winning the fight earns the Skillz trophy.
