Weapons

Introduction

Weapons in Build and Kill Zombies are called supports, and they come out of the SUPPORTS roll machine rather than the CAR PARTS machine. That distinction matters, because it means firepower and vehicle parts compete for exactly the same cash. A support piece bolts onto the chassis and only damages zombies it physically makes contact with, which turns placement into the single most important decision in the whole weapon system. The confirmed pieces are limited but distinct: the Glass Cylinder is a cheap uncommon starter that fits any small chassis, the Shredder is the spiked roller that flattens a wave on contact, and the Crossbow rolls from its own dedicated station and hits at range before a zombie reaches the bumper. How many supports you can carry at once is capped by chassis size and by the More Support skill ranks. This section covers what each piece does and where it has to sit.

Support Pieces & Placement

Confirmed Supports

Core Mechanics

Every support in Build and Kill Zombies is a physical object attached to the car, and damage only occurs where that object meets a zombie. There is no targeting, no lock-on and no attack button. A mount on the front face connects first; a mount on the roof or the rear is simply carried along and may never fire a single shot. That is why orientation in Build Mode is part of the weapon system rather than a cosmetic detail. Slot count is the second lever: the More Support skill ranks raise how many supports you can field, while chassis size decides whether there is a mounting point to put them on. Because supports roll from the SUPPORTS machine and parts from CAR PARTS, cash spent on firepower is cash not spent on going further, and the two pools are always in direct competition. Confirmed pieces remain few, so placement quality matters more than owning everything.

Advantages

Support pieces are genuinely differentiated rather than reskinned: the Glass Cylinder is a cheap contact starter, the Shredder converts dense waves into income, and the Crossbow reaches out before contact. Because supports roll separately from vehicle parts, you can deliberately target weapon upgrades when your distance is already adequate instead of gambling across a combined pool. Two weapon slots change a run far more than a marginal stat improvement, so the More Support skill ranks are among the highest-value permanent purchases available. Rarity and drop odds are shown on every roll result, which makes the machine transparent about what you are chasing. And because placement is free to change in Build Mode, a support that underperforms can be repositioned at no cost rather than replaced.

Challenges

Placement is the biggest trap in the game: a roof or rear mount can be a complete no-op, and because nothing tells you it never fired, the natural conclusion is that the weapon is broken. Confirmed support pieces are few, so there is not much room to tune a loadout or chase a specific niche. Contact weapons depend on the car still moving, which means a fuel failure silences your entire damage output at exactly the moment the run is ending. Supports also compete directly with fuel and engines for cash, and a player who over-invests in firepower ends up with a heavily armed car that stops before it meets anything worth shooting. Drop odds for the rarer pieces are not published, so planning around a specific weapon is unreliable.
