The GM 79 is a grenade launcher that appears in the Resident Evil 2 remake. This weapon is only retrievable in Claire's campaign.
- Claire Redfield: It is located in the weapons locker at the back of the Safety Deposit Room, requiring the Weapons Locker Key Card. If the player didn't pick it up in the RPD, the grenade launcher will instead be found in the Security Room in NEST where the player would normally find Acid Rounds.
- Konjac: Konjac has this weapon with attached Shoulder Stock in his inventory when the player begins The 4th Survivor mode.
- J. Martinez: Ghost can acquire this weapon with attached Long Barrel inside NEST from a Mr Raccoon Resupply machine in The Ghost Survivors mode.
The GM 79 is a grenade launcher in the game, its maximum magazine size is 1 by default.
In the UI (while aiming the weapon) or in the inventory screen, it is possible to see what round type is currently equipped based on the color of the small bullet shown (red for flame, yellow for acid).
By default the GM 79 takes up one space in the inventory, but once it is upgraded with the Shoulder Stock it will instead take up two spaces. Upgrading it with the shoulder stock will reduce its recoil and make each projectile travel in a more stable trajectory.
A versatile weapon capable of dealing with multitudes of enemies, from zombies to even the Tyrant and bosses with relative ease. Its mainstay feature of area of effect shots also plays into its strength, capable of hitting multiple targets in close proximity with a single shot. Ammo for it is relatively plentiful.
Its main drawback however is its slow reload speed and low capacity. Being a single shot weapon and needing to reload after every shot makes the sluggish reload speed very prevalent.
A veteran choice weapon when dealing with Birkin's mutations as Acid Rounds are able to stun it consistently, and with proper pacing it is capable of stunlocking the creatures for good until its eventual defeat.
