Yet Another Zombie Survivors - All Weapons
Every survivor has a weapon line that evolves through ranks. A rank 2 or 3 weapon outclasses the starting gear - here is every weapon, its element, and when it unlocks.
Core Weapon Mechanics
| Mechanic | Description | Priority |
|---|---|---|
| Auto-firing squad | Every survivor aims and shoots on their own. Your job is moving, dodging, and picking upgrades - a big part of the game's 'sit back and enjoy' appeal. | Core |
| Weapon evolution | Each survivor has a weapon line that evolves through ranks and upgrades. Evolve three weapons to their third-tier form in one run for the 'Three Times The Charm' achievement. | High |
| Elemental damage | Fire (Pyro), Ice (Huntress/Medic), Electric (Engineer) and Chemical (Medic) are the four elements. Each feeds a 1,000,000 damage achievement and element-specific goals. | High |
| Synergy system | Certain survivor combinations trigger synergies - for example SWAT's Grenade Trail can launch an EMP Grenade when Engineer is on the squad. Build around synergies for the strongest runs. | Core |
| Powerups and skills | Leveling offers perks, support skills and powerups. Focus a favorite character to alter their gear and unlock their ultimate abilities. | High |
| Rank and prestige | Kills rank up the leader (5k / 20k) and double their perk. Completing runs feeds the permanent upgrades, and the prestige system resets for account-wide power. | Medium |
Weapon Evolution: Ranks, Upgrades & "Three Times The Charm"
Every survivor has a weapon line that evolves through ranks and upgrades. Rank 2 unlocks (SWAT's Assault Rifle and Sniper Rifle, Tank's Minigun and Rocket Launcher, Engineer's Blaster and Laser, Pyro's Flamethrower and Infernax) outclass the starting gear by a wide margin, and upgrading them further pushes the gap.
Evolution is also an achievement: evolve three weapons to their third-tier form in a single run for "Three Times The Charm". Pick one survivor, keep buying their line's upgrades when they appear, and spread your picks across three different weapons instead of sinking everything into one.
All Weapons
Pistol (SWAT)
Element: Starter kinetic damage for the default leader
Role: Auto fire
Difficulty: Easy
SWAT's starting weapon. Reliable single-target kinetic damage that carries the first minutes before you buy or pick up something stronger.
SMG (SWAT)
Element: Spray-and-pray for early hordes
Role: Suppression
Difficulty: Easy
A faster firing option for thinning early crowds. Falls off against elites and bosses but great for wave cleanup.
Assault Rifle (SWAT)
Element: Balanced kinetic damage for mid-game hordes
Role: All-rounder
Difficulty: Medium
Unlocks at SWAT rank 2. A proven, effective tool that keeps pace with the horde through the mid game.
Sniper Rifle (SWAT)
Element: Horde-piercing shots for key targets
Role: Precision
Difficulty: Hard
Unlocks at SWAT rank 2. Powerful, horde-piercing shots that eliminate key targets - elite and boss focused.
Minigun (Tank)
Element: Huge sustained kinetic damage
Role: Heavy gunner

Tank's rank 2 unlock alongside the Rocket Launcher. Big gun, big damage - point it at the thickest part of the horde.

Difficulty: Easy
Tank's rank 2 unlock. Explosive splash that deletes crowds and clears bosses when the target group is dense.

Engineer's rank 2 unlock. A precision electric weapon for melting tougher enemies.
Flamethrower (Pyro)
Element: Fire AoE for crowds and elemental milestones

Role: Fire
Difficulty: Medium
Pyro's rank 2 unlock. A heavier fire weapon for melting elites and feeding elemental damage goals.

Huntress's rank 2 unlock. Arrows that explode on impact - strong against groups while keeping the archer range.
Freezing Arrows (Huntress)

Huntress's rank 2 unlock. Ice arrows that slow the horde - Huntress and Medic (rank 3) are the only ice damage dealers.
Kunai (Ghost)
Element: Rapid melee-range throwing
Role: Ninja
Difficulty: Hard
Ghost's core melee weapon. High attack speed suits the ninja-like close-range playstyle.
Freezing Flasks (Medic)
Element: Ice support damage

Signature Weapons in the 1.0 Update
The 1.0 update (August 2026) brought the roster to nine survivors and rebalanced weapon lines. Each survivor's signature weapon or ability and its evolution are listed below.
| Survivor | Signature | Evolution | Damage |
|---|---|---|---|
| SWAT | Ricochet | Ricochet: Shattering | Kinetic → Slashing |
| Tank | Bombing Strike | Bombing Strike: Bioweapon | Explosive → Chemical |
| Engineer | Turret family | Ice Turret | Ice & area control |
| Huntress | Bow line | Bow evolutions | Single-target ranged |
| Ghost | Kunai Dance | Kunai Dance | Slashing burst |
| Medic | Medical Drone & Syringer | Medical Drone | Support & Chemical |
| Pyro | Flamethrower | Flamethrower line | Fire |
| Mechanic | Cooling Mods | Cooling Mods | Ice conversion |
| Ranger | Crossbow | Crossbow + companions | Kinetic |
SWAT — The starting survivor's signature line. Patch 1.0.0c fixed Shattering so it deals Slashing damage again.
Tank — Tank's headline line. The Bioweapon evolution covers Chemical, a damage type few other lines reach.
Engineer — Engineer's signature is the turret family. Ice Turret registers as Ice damage since patch 1.0.0a.
Huntress — Huntress's arrows focus single targets. Her T2 and T3 firing arc was reduced from 30 to 20 in 1.0.
Ghost — Ghost's signature ability, visually reworked in 1.0.0b. Anchors the most-searched Ghost builds.
Medic — Medical Drone heals while stationary and attacks while moving. Syringer is Medic's Chemical option.
Pyro — Named in the Steam store description. Fire has the broadest status support after 1.0 raised activation chances.
Mechanic — New in 1.0. Cooling Mods rewrites weapon damage to Ice; patch 1.0.0b made its damage instance land before the weapon's own.
Ranger — The ninth survivor, unlocked at Survival Level 175. Crossbow is her signature, plus Good Boy and Falcon companions that buff the squad's Critical and Luck.
