Weapons

All 16 weapons in MeatSlicer, with exact stats pulled from js/weapons.js.

Weapons have no upgrade levels — their stats are fixed. All scaling comes from passive items and perks.

How weapons work

• You always carry the Bone Popper (infinite ammo sidearm) plus one special weapon in a holster slot.
• Press R to swap between them. Holstered weapons keep their remaining ammo.
• Picking up a new special weapon drops your current one (with its remaining ammo) so you can swap back.
• When a special weapon runs dry, you automatically fall back to the Bone Popper.
• Special weapons consume ammo per shot: 1 / ammoEff units per shot (so Brass Magazine's additive ammoEff stretches every magazine).

Where weapons come from

Source	Roll
Boss kill (guaranteed)	Rolled at floor + 2 — better tiers, earlier
Item room	35% chance alongside the item, rolled at current floor
Starting loadout	Bone Popper only

Drop weights by tier

Tier	Weight
0 (Common)	max(20, 60 − floor × 5)
1 (Uncommon)	30 + floor × 2
2 (Rare)	10 + floor × 3
3 (Legendary)	min(4 + floor × 2, 22)

Higher floors shift weight toward higher tiers. Tier 3 caps at weight 22.

Shared firing mechanics

• Volley system: items that grant split, fan, or rear shots add extra projectiles to every projectile weapon — parallel shots (±0.035 rad), angled shots (±0.16 rad per level), and backward shots respectively.
• Damage: weapon dmg × dmgMul (× critMul on crits — 5% base chance, ×2.0 base).
• Projectile lifetime (range): weapon range × rangeMul, in seconds.
• Homing: homing projectiles steer toward the nearest enemy within 320 px. Strength is 1.6 + homing × 0.7 for normal weapons with Homing Tumor; stronger bases for Eye Ballista and Swarm Jar (see below).

Tier −1 — Starter

Bone Popper

Trusty bone-shard sidearm

Damage	8
Fire interval	0.60 s
Projectile speed	540
Range (lifetime)	0.45 s
Ammo	Infinite
Behavior	Single bullet
Recoil (punch)	0.42

Your eternal fallback. Never runs dry, never holstered — swapping with R always brings it back.

Tier 0 — Common

Ribcage Repeater

Rattles off rib slivers

Stat	Value
Damage	6
Fire interval	0.09 s (very fast)
Projectile speed	560
Spread	0.10 rad
Range	0.42 s
Ammo	140
Recoil	0.18

Rapid-fire bullet hose. Low per-shot damage, excellent proc-per-second carrier for on-hit item effects.

Marrow Scatter

A devastating close blast of jagged bone

Stat	Value
Damage	11 per pellet
Pellets	6
Fire interval	0.58 s
Projectile speed	500
Spread	0.55 rad (wide)
Range	0.38 s (short)
Ammo	42

Tier 1 — Uncommon

Cleaver Cadence

It always comes back

Stat	Value
Damage	15
Fire interval	0.38 s
Projectile speed	400 (returns at up to 520)
Range	1.10 s
Ammo	34
Recoil	0.42

Boomerang: flies out while decelerating for 0.45 s, then accelerates back to you (caught within 20 px). Always pierces — it can hit enemies on both the outbound and return trip.

Sawblade Launcher

Bouncing, hungry steel

Stat	Value
Damage	13
Fire interval	0.34 s
Projectile speed	360
Wall bounces	5 (plus bounces from Ricochet Ribs)
Range	0.60 s
Ammo	26
Recoil	0.45

Spinning ricochet blades. Deadly in cramped rooms where blades ping off walls into packs.

Hemophage

Drinks what it touches

Stat	Value
Damage	8
Fire interval	0.19 s
Projectile speed	480
Range	0.45 s
Lifesteal	12.5% chance per hit to heal 1 HP
Ammo	44
Recoil	0.35

The only weapon with built-in lifesteal. Healing only procs while you're below max HP.

Eye Ballista

The eyes follow. They always follow

Stat	Value
Damage	10
Fire interval	0.30 s
Projectile speed	320
Range	0.62 s
Homing	6 + homing × 0.7 (strongest base homing)
Ammo	32

Tier 2 — Rare

Bile Blunderbuss

A brutal corrosive torrent; pools linger

Stat	Value
Damage	7
Fire interval	0.12 s (rapid, hold to spray)
Projectiles per shot	2
Projectile speed	340
Spread	0.32 rad
Range	0.36 s
Pierce	2 (+ item pierce)
Ammo	70
Recoil	0.34

Corrosive cone spray. On hit: slows for 1.6 s and 45% chance to leave an acid pool (radius 24 × sizeMul, 3.5 s life, DPS = bullet damage × 1.5). Projectiles that expire mid-flight have a separate 35% chance to drop a pool.

Gut Hook

Impales and drags the catch

Stat	Value
Damage	48 (+ 50% = 24 bonus when the drag ends)
Fire interval	0.85 s (slow)
Projectile speed	720 (fastest projectile)
Range	0.60 s
Ammo	14
Recoil	0.95

Harpoon that pierces everything and drags the first non-boss enemy it hits along its flight path. When the projectile expires, the dragged enemy takes 50% of the bullet's damage again. Excellent for yanking a priority target out of a pack.

Flesh Masher

Lobs ground-meat bombs

Stat	Value
Damage	34 (area of effect)
Fire interval	0.75 s
Behavior	Lobbed to cursor, explodes on arrival
Blast radius	85 × rangeMul × √sizeMul
Ammo	14
Recoil	0.90

Grenade lobber. Flight time auto-computed from distance (clamped 0.12–0.8 s). The blast damages and knocks back everything in radius. Arcs over the chaos — no line of sight needed.

Trap Queen

Bear traps. For bears. And worse

Stat	Value
Damage	10 per trap trigger
Fire interval	0.55 s
Behavior	Lobbed; leaves a trap where it lands
Trap life	12 s × rangeMul
Trap radius	16 × sizeMul
Ammo	12 (refills at 75% rate — ammoWeight: 0.75)
Recoil	0.65

Area denial. Traps persist on the floor and damage any enemy that steps on them — pre-lay them along doorways and kiting paths.

Red Right Hand

A chainsaw that liquefies anything in reach

Stat	Value
Damage	7 per tick (ticks scale with fire rate)
Damage interval	0.10 s
Reach	30 × rangeMul × √shotSpeedMul from player
Arc radius	34 × √sizeMul
Ammo	160 (drains 18/sec while held, ÷ ammoEff)
Recoil	0.38

Continuous melee chainsaw — hold LMB and walk into things. Damage scales with dmgMul × rateMul, plus the same +6%-per-pierce/bounce/homing inert bonus as the Tenderizer. Sparks fly, ammo drains.

Tier 3 — Legendary

The Cauterizer

Incinerates anything brave enough to get close

Stat	Value
Damage	4.5 per flame tick
Fire interval	0.05 s (20 ticks/sec, hold to spray)
Projectiles per shot	2
Projectile speed	310
Spread	0.34 rad
Range	0.36 s (very short)
Pierce	2 (+ item pierce)
Ammo	110
Recoil	0.32

Flamethrower. Hits ignite for 2.2 s with burn DPS = bullet damage × 2 (9 DPS base). Melt hordes that get close; useless at range.

The Tenderizer

A room-shaking close-range meat paste

Stat	Value
Damage	60 (instant area hit)
Fire interval	0.58 s
Range	46 × rangeMul × √shotSpeedMul from player
Blast radius	70 × rangeMul × √sizeMul
Ammo	26
Recoil	1.00 (max), screen shake 5

Point-blank slam — no projectile, an instant circular blast in front of you. Bonus "inert" damage scaling: +6% per point of pierce + bounce + homing you own.

Spinal Tap

Charge it. Delete a line of meat

Stat	Value
Damage	95 (× 0.4–1.0 by charge)
Charge time	0.85 s (minimum 40% charge = 0.34 s to fire)
Beam length	900 × rangeMul
Beam width	14 × √sizeMul
Ammo	9
Recoil	1.00, screen shake 8

Hold LMB to charge, release to fire an instant hitscan beam that deletes everything in a line. Damage scales 0.4 + 0.6 × charge fraction — full charge is 2.5× a hasty snap shot. A ring around your character shows charge state (blue = full). Charge rate scales with rateMul × √shotSpeedMul.

Swarm Jar

A jar of friends. They are hungry

Stat	Value
Damage	9 per maggot
Fire interval	0.80 s
Maggots per jar	6 (+ split + fan bonuses)
Maggot speed / life	260 / 2.2 s × rangeMul
Maggot homing	8 + homing × 0.7 (strongest in game)
Ammo	7 (refills at 80% rate — ammoWeight: 0.8)
Recoil	0.70

Lobs a jar that shatters into a pack of homing maggots. Maggots inherit your pierce and bounce stats and relentlessly chase enemies for their full lifetime. Throw and forget.

Damage math reference

bullet damage  = weapon dmg × dmgMul × (critMul if crit)
fire interval  = weapon interval / (rateMul × frenzyMul)
proj speed     = weapon spd × shotSpeedMul
proj lifetime  = weapon range × rangeMul
ammo per shot  = 1 / ammoEff
knockback      = 90 × knockbackMul

• Crit: base 5% chance, ×2.0 damage. Raised by Bloodshot Eye / Hollow Needle (items) and Bone Splitter / Cold Precision (perks).
• Frenzy: from Dead Man's Switch — kills grant 1 + frenzy fire rate for 3 s.
• Slam/saw/beam weapons (Tenderizer, Red Right Hand, Spinal Tap) get an extra 1 + (pierce + bounce + homing) × 0.06 multiplier instead of firing extra projectiles.
