Rocket launcher/Doom Eternal

The Rocket Launcher, also called the Paingiver, is a weapon in Doom Eternal. It has been redesigned from its previous incarnation to be based on the UAC Cultist technology and even the Doom Hunter's arm cannon. Its Remote Detonation and Lock-On Burst mods return from DOOM, but they appear to function differently in terms of upgrades and mastery.

Comparatively to its previous counterparts, the Rocket Launcher does a heavy amount of damage with both impact and splash being increased. Less ammo is carried, with it topped off at 13 rockets max making constant resupplies required.

Obtaining the Weapon
The Rocket Launcher is first encountered in the Cultist Base, just before the arena where the Slayer encounters the Whiplash demons for the first time. After finding the Cultist Key, head through the locked gate marked "Cultist Key," kill the shield soldiers and keep going until you encounter a shootable green button that opens up a barricade above it with a vent with a punchable green crack in it. Shoot the button, double-dash to the vent, punch through it, and then drop down once you're through to grab the Rocket Launcher.

Lock-On Burst
Hold Mod Button to lock onto a target. Once Locked, firing the weapon will launch three rockets at the target.

Ammunition
The player can increase his max ammo cap by using Sentinel Crystals and allocating its power to "Ammo" subsystem.

Weapon Skins
As with most other weapons in Doom Eternal, the Rocket Launcher has several weapon skins available.
