M79

Lore & Background

In the Rust world, the M79 is not manufactured; it is scavenged. The post-collapse landscape is littered with the detritus of a military that no longer has a chain of command, and weapons like the M79 surface in supply caches, abandoned outposts, and the hands of well-networked traders. Its single-shot design, once a logistical simplicity in a field army, becomes a deliberate tactical choice in a world where a single well-placed round can level a two-story base and scatter its occupants across the overgrown terrain.

Survivor communities tend to treat the M79 with a mix of reverence and caution. It is the kind of weapon that a small, tight-knit group can field, but the moment it is fired near a settlement, the political consequences are immediate. Alliances fracture. Retaliations are planned. The M79 does not just destroy structures; it destroys the fragile social contracts that keep the wasteland from becoming a free-for-all at every intersection.

There is a particular grim poetry to the M79 in this setting: a weapon designed for a soldier to lob over a ridge at an entrenched enemy, now pressed into service against prefab walls, metal plates, and the stubborn hope of a group that spent three weeks building a home out of scrap.

Reader's Guide

The M79 is a Tier 3 single-shot launcher that fires one 40 mm high-explosive round per trigger pull. Its damage is delivered in a wide splash radius, making it punishing against grouped targets and extremely effective against walls, floors, and vehicle hulls. Rate of fire is the defining limitation: you get one round, then a reload window that leaves you exposed.

Crafting requires Metal Fragments, Gun Powder, Cloth, and Sulfur, placing it firmly in the mid-to-late-game resource bracket. You will not be pulling one out of a Tier 1 cache; it is a deliberate investment of gathered materials.

In a loadout, the M79 slots in as your area-damage and structure-breaker. Pair it with a fast-firing sidearm (9 mm SMG, pistol, or rifle) for the close-quarters follow-up, and carry a shield or body armor to survive the reload window. It is not a primary dueling weapon; it is the tool you pull when a base is too thick for your rifle to chew through quickly.

In the current meta, the M79 remains a staple of organized raids and base-defense denial, though its single-round nature means it rewards positioning and timing over raw aggression. Against a well-armored, spread-out group it can feel underwhelming; against a clustered compound it is simply the most efficient demolition tool in the game.

Did You Know?

• The M79 in Rust is a single-shot weapon: you fire one 40 mm round, then must reload before you can fire again, making positioning and timing far more critical than with fully automatic options.
• Its 40 mm high-explosive round deals damage in a radius, meaning it can hit multiple players or multiple sections of a structure with a single shot, which is why it is a go-to for base raiding.
• Because the M79 is Tier 3, it sits above the more common Tier 1 and 2 firearms in the crafting and loot hierarchy, making it a meaningful power milestone for a survivor working their way up the tech tree.
