The Chainsaw is a returning special weapon featured in Doom (2016). It is not on the weapon wheel and is instead used with a special button (like the BFG 9000). According to UAC report, the weapon was smuggled into the Argent Facility for unknown reasons.
The chainsaw is a quick-kill weapon, capable of destroying powerful enemies like the Hell Knight and Cyber-Mancubus in a single well-placed hit. The weapon is, for the first time, realistically limited by using fuel as ammunition, in order to balance its lethality and to provide a mechanic to encourage its use. Killing enemies with the chainsaw causes a massive drop of ammunition for other weapons, making it a key way to restock supplies. Stronger enemies require more than one unit of fuel to kill with the chainsaw.
When used on an enemy, it insta-kills it featuring a bloody and gory animation as the demon is dismembered or cut in half. Enemies killed with the chainsaw always drop ammunition pickups. It utilizes fuel as an ammo counter, with pick-ups taking the form of a fuel container, and larger enemies requiring more fuel to perform the insta-kill. If the fuel level is depleted, the chainsaw cannot be utilized beyond a simple melee attack. Chainsaw kills count as Glory Kills for rune effects and the like.

The player can increase his max ammo cap by using Argent Cells and allocating its power to "Ammo" subsystem.

The Chainsaw is one of the 3 Power Weapons in Multiplayer, which insta-kills every normal enemy, however due to close range it has limited value. Also, utilising the chainsaw when there is no enemy to use it on will waste a fuel cell. Use with the Haste and Invisibility powerups is highly advantageous. As with the BFG 9000 and the Gauss Cannon, the Weapon Mod allows the user to see enemies through walls.
The chainsaw featured in Bethesda's conference during the first level shown is referred to by in-game text as the "Super Chainsaw", and mysteriously has an ammo counter that read 6 throughout the demo. It insta-killed all small enemies it was used on, however it wasn't shown working against larger enemies.
- Occasionally, the Chainsaw will not go through its animation when killing an enemy in either Campaign or Multiplayer. Instead, it will act like its earlier iterations.
