Routes and locations
Structural blocks are built from refined resources through hand refinement and Craftbot recipes rather than found as complete vehicle frames.
Refined resource chain
Process wood, stone, and metal resources into the matching block families.
Open related entry →Craftbot
Use the available recipes for higher-grade or specialized structural materials.
Open related entry →- Choose material by weight and durability, not appearance alone.
- Test the empty chassis before replacing it with heavier blocks.
- Keep repair material that matches the important frame sections.

Farmbots can destroy low-durability blocks simply by walking over them. Metal Block 3 is the practical defense ceiling.
Durability Is Chance, Not HP
When a bot hits a block, the game rolls against that block’s durability level. Soft materials fail often; high tiers almost never. That is why a thin scrap-wood “armor” wall fails on raid night even if it “looked thick.”
Put Expensive Material Only on Contact Faces
A vehicle or farm killbox should use Metal-tier blocks on the first impact surface and cheaper structure behind it. Armoring every decorative panel with Metal 3 wastes weight and Component Kit crafting time.
- Wheels → bearings → frame load path first.
- Raid approach wall second.
- Paint and bodywork last.
Farmbots Punish Soft Floors
Farmbot melee tables show 100% break chance on durability 1–3 and still threaten mid tiers. Do not let a Farmbot path across scrap-wood decking that holds your Craftbot or ammo chests.
Prototype Cheap, Reinforce Proven Paths
Validate steering and tool mounts in scrap wood, then replace only the load paths that survived testing. That keeps early Survival mobile without committing Metal 3 to a bad chassis.
