Build and Kill Zombies Builds & Parts — Odds and Vehicles
Every documented Build and Kill Zombies part with roll odds — engines ladder 1 in 3 to 1 in 12,500, fuels, wheels, blocks and supports, plus blueprint vehicles and build tips.
Every documented Build and Kill Zombies builds input lives on this hub: the part categories, the roll odds read from the in-game Index, blueprint vehicles and how they fit together. A build in this game is a car assembled from rolled parts — the lobby already shows fully kitted zombie crushers rolling on the same pads where new players start with a bare chassis, and the difference between the two is almost entirely what the roll machines have paid out.
The Four CAR PARTS Categories
Build Mode splits every vehicle into four part categories that roll from the CAR PARTS machine:
| Category | What it controls | Documented parts |
|---|---|---|
| Blocks | Chassis and mounting points | Glass Slab, Passenger Seat |
| Engines | Top speed and acceleration | Small Engine |
| Wheels | Grip and weight | — (locked slots read as ??? in-game) |
| Fuels | How long a run can last | Small Tank, Fuel Barrel |
A separate Supports machine rolls weapons and defensive pieces — Wooden Spike, Flamethrower, Tubex — and a Weapons tab in the in-game Index tracks offensive parts like the Double Barrel shotgun and the event-added Cursed Katana. Four of these categories display their own odds ladder in the Index; entries the camera has not read yet are listed as "(to be verified)" rather than guessed.


The Engine Odds Ladder (Complete)
Engines are the only category fully read from the in-game Index so far — ten slots, from a 1-in-3 starter to a 1-in-12,500 endgame pull:
| Ladder slot | Odds | Documented part |
|---|---|---|
| 1 | 1 in 3 | Small Engine |
| 2 | 1 in 6 | (to be verified) |
| 3 | 1 in 14 | (to be verified) |
| 4 | 1 in 40 | (to be verified) |
| 5 | 1 in 90 | (to be verified) |
| 6 | 1 in 150 | (to be verified) |
| 7 | 1 in 375 | (to be verified) |
| 8 | 1 in 750 | (to be verified) |
| 9 | 1 in 10,000 | (to be verified) |
| 10 | 1 in 12,500 | (to be verified) |
Rolling engines first is the standard opening because the ladder starts at 1 in 3 — the fastest route from a naked plot to a first drivable car. Work out how many rolls a target tier takes with the roll odds calculator.
Documented Parts So Far
Per-category deep dives with their own ladders and evidence: engines (the complete 1-in-3 to 1-in-12,500 ladder), supports (Wooden Spike through the $10,000 Flamethrower) and weapons (the Legendary Double Barrel and the Shredder line). Not sure what to chase next? The Part & Build Finder plans it from what you own, and the roll odds calculator prices the grind.
Parts confirmed on camera or through code rewards, with the evidence each number came from:
| Part | Category | Odds | Value | Evidence |
|---|---|---|---|---|
| Small Engine | Engines | 1 in 3 | — | Index read on footage |
| Wooden Spike | Supports | 1 in 3 | $10 | Pickup popup on footage |
| Flamethrower | Supports | 1 in 9 | $10,000 | Pickup popup on footage |
| Double Barrel | Weapons | 1 in 10 | $2,200 | Pickup popup — Legendary tag |
| Small Tank | Fuels | — | — | COMMUNITY code reward |
| Fuel Barrel | Fuels | — | — | Vehicle inventory on footage |
| Glass Slab | Blocks | — | — | Vehicle inventory on footage |
| Passenger Seat | Blocks | — | — | MOREFRIENDS code reward |
| Tubex | Supports | — | — | Seen mounted, odds not shown |
| Cursed Katana | Weapons | — | — | In-game what's-new panel |
The only rarity band name read from the game so far is Legendary (on the Double Barrel pickup card) — a full rarity ladder would be guesswork until the remaining band names are read.
Blueprint Vehicles
The Car Builds panel lists blueprint vehicles — pre-designed builds such as Fast Furious and Blue Monster — each showing the Required Parts (icon counts like x10, x1, x4) and a green Spawn button rather than a cash price. When parts are missing, a Missing Parts panel lists exactly what you still need with a coin top-up price per part.
That makes blueprints the middle path between rolling and hand-building: they tell you the exact shopping list, and every part on it comes from the same roll machines. The beginner guide walks the first-run order of operations, and the skills guide covers the Luck upgrades that make every roll cheaper in the long run.
How a Build Comes Together
- Roll an engine first — the 1-in-3 Small Engine is nearly guaranteed within a few pulls.
- Fill fuels and wheels — fuel sets run length; a dry tank ends a push wherever it is.
- Mount one front support — Wooden Spike at 1 in 3 clears early waves while you save.
- Bank a run — distance and kills both pay cash; the payout funds the next round of rolls.
- Compound with Luck skills — Luck II and Luck III multiply every future roll before any weapon upgrade.
