GRAIN ROT weapons tier list: what to buy, and in what order
Quick answer
Rank the weapons by the job they do on a run rather than by damage. The Sword and the Gun top most published rankings, the Hammer is the best all-rounder because it demolishes and fights, the Mallet is a demolition tool that should never be your weapon, and bare hands come last. Weapons come from Outpost inventory tiers and Murch's shop rather than from loot in the ruins, so your order of purchase is a progression decision, not lucky RNG.
How this ranking is built
Four things decide a weapon's place here, and damage is only one of them. Demolition speed sets how fast a loot loop runs. Combat value decides whether you survive a bad room. Noise decides whether the rest of the floor comes to visit, and the store page confirms the Corrupted react to sound, movement and each other. Unlock depth decides how much Gold and Outpost work stands between you and the weapon.
That is why the list is not simply strongest first. Your vessel is fragile and the crew's loot is lost if everyone goes down, so a weapon that shortens a run without being loud usually beats a weapon with higher damage. Where published rankings disagree, this page says so instead of hiding it.
The tier list
| Tier | Weapon | Why it lands there |
|---|---|---|
| S | Sword | The best melee pick in the game. Reliable damage, forgiving timing, and it clears a path in tight rooms. Its weakness is demolition — it can break objects, just inefficiently — so leave salvage to the Hammer or the Mallet. |
| S | Gun | The only confirmed ranged option, and range is worth a lot against enemies that want to close on you. The catch is noise: fire it standing still and you summon the floor. Rankings disagree here — some put the Gun in S, others in A — which tells you the noise tax is real but playstyle-dependent. |
| A | Hammer | The most balanced tool in the game and the one most players should build around. It demolishes faster than the Mallet and still hits hard enough to hold a doorway, so you rarely switch mid-fight. Some rankings put it in S for exactly that versatility; it stays in A here only because the Sword kills more cleanly. |
| B | Mallet | Excellent demolition, no combat. It is the tool Murch hands you at the start and it does that early job well — weak props, shallow furniture, tutorial objectives. Against the Corrupted it only threatens the smallest ones. Treat it as a placeholder, not a loadout. |
| C | Bare hands and emotes | Nothing. Hands cannot demolish resources and cannot hold a fight, and emotes are for trolling your crew. If you are stripped of every weapon, a few punches will not change the outcome. |
The stat the game never shows you
Noise is the hidden column in every weapon comparison. A Hammer swing is loud enough to matter, a Gunshot is a beacon, and the Corrupted hunt by sound. That is why a quiet demolition tool keeps a place on real runs even after you own better weapons: fewer noise events per run means fewer unplanned fights.
It is also the reason to set a crew rule early. The suggestion that shows up again and again in community discussions is simple — no gunfire until extraction is called, or until an Elite appears. That single rule turns the Gun from a liability into an emergency button.
Buy order: what to spend Gold on first
| Priority | Spend | Reason |
|---|---|---|
| 1 | Better gear from Murch | Murch's shop stock improves as you upgrade his room, and weapons are the purchases that change a run most. Carry anything valuable home — gear is rare and expensive, and you lose what you are carrying if the run fails. |
| 2 | Outpost inventory tiers | Weapons sit behind Outpost inventory tiers rather than in the ruins, so the Outpost is what actually unlocks firepower. Progress there before buying luxuries. |
| 3 | Extraction headroom | Keep enough Gold to pay the elevator's return fare instead of spending it all in the shop. The fare rises the deeper you go, and being unable to pay your way out with a full haul is the most expensive mistake in the game. |
| 4 | Cosmetics | Last. Questionable cosmetics change nothing about survival. |
Weapons are unlocked, not found
Weapons do not drop from the ruins. They come from Outpost progression — inventory tier rooms and Murch's shop — which is why the Mallet is the tutorial default and the Hammer, Sword and Gun open up as your inventory tiers rise. Because Outpost progress is shared in co-op, agree on a spending order before anyone commits Gold, or one player's impulse buy becomes the crew's missed unlock.
The four-player loadout spread
| Role | Weapon | Job |
|---|---|---|
| Demolisher | Hammer or Mallet | Clears furniture and feeds the Grinder — the run's actual income. |
| Anchor | Sword | Holds doorways and chokepoints so the demolisher can keep working. |
| Flex | Gun, holstered | Stays quiet until an Elite or a wipe starts, then punches a hole for the retreat. |
| Scout | Light kit | Pathfinding, fuse and shop sweeps, and finding the way back to the elevator. |
Confirmed facts vs community reports
The roster above — Mallet, Hammer, Sword, Gun and bare hands — appears consistently across published launch coverage including Destructoid, and the Outpost-tier unlock route is corroborated by multiple guides. The tier letters themselves are editorial: outlets disagree on whether the Gun and the Hammer belong in S or A, and this page resolves that from the loot-loop criteria above rather than from raw damage. Two details remain community-observed rather than official: the Scrap Blaster seen at 350 Gold, and the claim that the Sword arrives specifically at inventory tier three. Treat the roster as solid and the fine numeric detail as something to confirm in your own Outpost.
