This article is about the weapon in Doom Eternal. For other versions of this weapon, see:

The chainsaw returns as a weapon in Doom Eternal, with much of its functions and appearance based on its previous counterpart from Doom (2016). It remains a limited-use "power weapon" which can be used to kill even powerful enemies quickly, so long as sufficient fuel is available. Kills made with the chainsaw reward the player with ammo drops. It has a special key assigned to it to make it easier and quicker to use it against demons to get ammo drops. It is introduce as early as Hell On Earth, as a mandatory pickup required for the game to continue, as it is the player's primary source of obtaining ammo, since the pickups and the maximum ammo capacity have been drastically reduced since Doom (2016).

The blade of the chainsaw refers to itself as the Mixom Bucktooth Dopesaw. This is a reference to Doom 3, where Mixom chainsaws had been delivered erroneously to Mars, and to the Dopefish, which is also seen as a secret in the polar Cultist Base level.

Tactical analysis[edit]

Like in Doom (2016), the chainsaw instantly kills enemies it is used against but requires fuel to be used. Due to its ability to force slain monsters to drop large quantities of ammo, it is a key part of the basic combat loop in Doom Eternal alongside glory kills and the flame belch.

Fuel usage[edit]

The chainsaw now has a maximum of three fuel units, with one always recharging on its own. This makes it possible to regularly use the chainsaw against fodder-tier enemies without need for fuel pickups, greatly increasing its value as a way of obtaining ammo for other weapons.


The Night Sentinel weaponmasters had a saying: "it is the warrior that makes the weapon great". The Slayer's unconventional choice of adding a chainsaw to his arsenal has proven their adage right time after time thanks to its capabilities for dismemberment.
