Equipment Launcher

The Equipment Launcher is a weapon in Doom Eternal. It is a small cannon mounted on the shoulder of the Doom Slayer's Praetor Suit, providing support fire as he mows down demons with his primary weapons.

The Equipment Launcher can fire three types of ordnance, none of which require ammunition; instead, each function recharges over time.

Flame Belch
The Flame Belch shoots a plume of fire from the Equipment Launcher, setting enemies alight if they're caught in it. A burning enemy will be immobilized as long as they're engulfed in flames, and drops armor points when shot with other weapons.

Ice Bomb
The Ice Bomb releases a freezing explosive from the Equipment Launcher, flash-freezing enemies for a short period of time. It can utilized to immobilize a group of enemies before they do any serious damage, as well as allow for an opportunity to shatter enemies with a mighty blast from the Super Shotgun.

Frag Grenade
The Frag Grenade is the simplest of the Equipment Launcher's options; it blows stuff up. This is the launcher's strongest weapon for damage output, being able to wipe out Fodder-class demons in a single burst - especially effective if they're in groups.

Codex description

 * Custom-built to fit the Doom Slayer's Praetor Suit, this shoulder-mounted ordnance system is modified to serve a variety of combat roles. Designed as a universal munitions platform, the Equipment Launcher is capable of alternated its armament configuration with the press of a switch, activated by a reflex senor located on the interior of the Praetor Suit's gauntlet. In its Flame Belch configuration, the Launcher spits a gout of fire exceeding 1000°C, setting even the sturdiest of demons aflame. While in its Grenade Launcher configuration, the Launcher fires a traditional UAC-model frag explosive, a projectile-based payload not dissimilar to that of the Ice Bomb, wherein the Launcher fires a EYE-C40 gas canister to flash-freeze nearby targets.
