Weapon

The pistol being held in MAP01 of Doom 2.

A weapon is used by the player to attack opponents. It is displayed onscreen as part of the body of the player character to simulate a first person perspective. In Doom, it is the main aspect of the game action.

Each appears in the form of an item that, when picked up, provides the player with an additional weapon with which to attack opponents, as well as some ammo for the corresponding weapon. Normally, weapons are either placed in levels by the designers or dropped by dying opponents (such as zombies in the Doom games). Once a weapon is picked up during a game, any additional weapons of the same type will count only as ammunition.

Each weapon has advantages and disadvantages when used against a given monster. Broadly speaking, however, the larger weapons do more damage but are harder to find and harder to keep stocked with ammunition. In each game, one or two weak weapons require no ammo and are therefore always available, except Doom Eternal.

In Classic Doom's multiplayer co-op since the game doesn't restart the level when any player dies and players can easily respawn, any weapons that were placed in the level won't disappear after its been picked up. This allow this to be an infinite source for that kind of weapon. However this does not make it an infinite source for ammo. Because of this all available players can repeatedly pick the weapon up either during the first time in level in the current playthrough or to regain it after the player had respawned after their character died. Any weapons dropped by enemies will disappear when pick up.

Doom games

No matter which weapon a player is wielding, his sprite (in multiplayer games, or source ports with a "chasecam" mode) is perpetually shown to be armed with the same generic assault rifle as the former humans; a weapon similar to this, although presumably intended to be the chaingun, appears on the game's title screen.

Doom Alpha

Early alpha releases of Doom armed the player with a semi-automatic rifle, optionally equipped with a double-bladed bayonet as a melee weapon. This weapon was not included in the finished game. The rifle sprites revealed the player character to be wearing elbow pads, which can still be seen on the player character sprite. A few other weapons were also included in the alpha versions.

Doom

• Fists: Extremely basic close-range weapon. Never runs out of ammo, but only about as powerful as a pistol shot; normally used only as a last resort or with a berserk powerup.
• Chainsaw: Does damage like the normal fist, but four times faster.
• Pistol: The default long-range weapon. Almost entirely useless against anything stronger than a zombieman or shotgun guy.
• Shotgun: A good general-purpose weapon capable of dealing medium-high damage, especially at close range. Also works better at longer ranges than the super shotgun.
• Chaingun: Very good against large crowds of small monsters or single large monsters, but its rapid rate of fire can quickly deplete its ammo supply.
• Rocket launcher: Fires explosive rockets. Does a lot of damage, but can also seriously hurt the player if used indiscriminately at close range.
• Plasma gun: Shoots pulses of blue-hot plasma at high speed, which can take down groups of incoming enemies easily — if aimed properly.
• BFG9000: The "Big Fucking Gun." Somewhat counter-intuitive to operate at first, but kills almost any monster in one shot.

The chaingun and pistol both use the same ammo type (bullets), so using either will also affect the other in ammo. The shotgun and super shotgun (see below) also share their ammo pool (shells) as do the plasma gun and BFG9000, which both use cells.

Doom II

All of the above weapons, with the addition of:

• Super shotgun: A double-barrelled, sawed-off shotgun which takes even longer to reload, but at close range is even more deadly than the regular shotgun.

Doom 64

All of the above weapons, with the addition of:

• Unmaker: A demonic laser gun which rapidly fires paralyzing red slugs but can be upgraded in firepower by the collection of Demon Keys. The red slugs stun monsters, temporarily rendering them unable to attack for about 2-3 seconds. Monsters are still able to move, however.

Doom RPG

Doom RPG includes versions of the pistol, shotgun, super shotgun, chaingun, rocket launcher, plasma gun, and BFG9000, as well as two new weapons, the fire axe and fire extinguisher.

Doom 3

All of Doom's weapons are present in some form in Doom 3, with the addition of:

• Flashlight: Not a weapon per se, but it doubles as a crude club.
• Machine gun: Similar to the chaingun, but not as powerful, but with more accurate shots.
• Grenades: Standard thrown fragmentation grenade on a timer.
• Soul cube: Charged by killing monsters, and then released as a powerful seeking weapon that transfers health from the monster it hits to the player.

Resurrection of Evil

The Doom 3: Resurrection of Evil expansion pack contains all of Doom 3's weapons except the Soul Cube and the Chainsaw, but introduces a version of the gravity gun called the Grabber, and includes the super shotgun (as in Doom II). It also introduces an artifact somewhat like the Soul Cube.

Doom Eternal

The majority of the weapons from Doom (2016) return, along with some new additions:

• Chainsaw - Retains the ammo-restoring capabilities of Doom (2016), but it now restores one tick of fuel over time.
• Combat Shotgun - A general purpose weapon which deals decent damage but has a short range. Returns from Doom (2016), and now takes the place of the player's starting weapon.
• Heavy Cannon - A fully automatic bullet hose which can fire either a high-damage precision shot or a barrage of micro missiles. Functionally, the Heavy Cannon is near-identical to the Heavy Assault Rifle from Doom (2016).
• Plasma Rifle - A fast-firing energy weapon with the ability to overload enemy shields. Returns from Doom (2016), albeit with a redesign resembling the classic look.
• Rocket Launcher - Fires powerful rockets which can either lock onto enemies or be remotely detonated. Returns from Doom (2016) with a visual redesign.
• Super Shotgun - The Doom Slayer's personal Super Shotgun. It now features a meat hook, which allows the player to pull themselves towards enemies.
• Ballista - A slow-firing but heavy-hitting energy weapon which uses the same ammunition as the Plasma Rifle. Replaces the Gauss Cannon from the previous game.
• Chaingun - A fast-firing bullet hose which shares its ammunition with the Heavy Cannon. Returns from Doom (2016).
• BFG 9000 - An extremely powerful weapon which fires a ball of green energy. Tendrils will snake out from the projectile towards nearby demons, dealing massive amounts of damage. Returns from Doom (2016).
• Unmaykr - A re-imagining of the Unmaker from Doom 64, now with a Maykr aesthetic. Uses the same ammo pool as the BFG and can only be unlocked after completing all six Slayer Gates.
• Crucible - A new melee weapon which can kill any non-boss demon in a single hit. The Crucible requires ammo pickups which, like BFG ammunition, can only be found in certain areas of the map.

The Doom Slayer additionally comes equipped with the Doomblade - a wrist-mounted retractable blade which is used in many glory kills - and the Equipment Launcher . The Equipment Launcher is used to activate the Slayer's flame belch and fire either fragmentation or ice grenades at enemies.
