Lore

A very basic zombie. Nine peas are enough to defeat it. This kind of zombie is extremely common, but when too many gather at once, it is still not easy to handle. Sometimes seeing four Basic Zombies makes one wish they were a Conehead or Buckethead instead.

Basic Zombie itself does not have many tricks, but Archer Zombie can activate it into another zombie, or simply make it faster and tougher as a Silver Chariot. Basic does not mean harmless.

Mechanics

Role

Basic walking zombie

  • Durability: about 9 peas; normal speed.
  • No armor and no special attack; the most basic source of pressure.
  • Can be activated by Archer Zombie into another zombie that has appeared in the battle, or into a stronger Silver Chariot.
  • When numbers build up, it can still occupy a lot of firepower.

Advanced mechanics

Basic Zombie's advanced mechanics are deliberately plain: it is the calibration body for the zombie roster, the easiest target to count, and the most exposed recipient of external upgrades. Its danger comes less from one body than from how many bodies occupy a lane before Archer Zombie, Magnet Truck Zombie, or other support can turn them into something less basic.

270 HP body and 90 HP critical reserve

A normal Basic Zombie's body maximum is 270 HP. It has no armor layer and no special attack sequence. The familiar 180 HP value is not the full body pool; it is the work to reach the critical window after subtracting the roughly one-third reserve: a 270 HP body leaves a 90 HP critical reserve, so the front segment is about 180 HP.

Advanced mechanics should keep body maximum, critical reserve, and work-to-critical separate. A normal Peashooter shot deals 20 damage, so the diary hit-count shorthand comes from the 180 HP work-to-critical reading; other attacks should be compared by their own damage and interval. Slow, freeze, knockback, and walls change the time the zombie remains available to be shot rather than changing the body itself.

Hbody,max=270 HP,Hcritical reserve=90 HP,Hto critical=270−90=180 HPH_{\text{body,max}}=270\text{ HP},\quad H_{\text{critical reserve}}=90\text{ HP},\quad H_{\text{to critical}}=270-90=180\text{ HP}
Basic Zombie is the body-only yardstick: body maximum 270 HP; the common removal reading is 180 HP after subtracting the 90 HP critical reserve.

Density pressure in a lane

One Basic Zombie is usually a tempo check. Several Basic Zombies are a fire-allocation problem: shots still remove bodies one by one, overkill on the front target is lost, and back targets continue walking while the first target absorbs the current cycle.

Regular zombies also do not need to stay perfectly synchronized. Small speed and spawn-time differences decide whether they arrive as a clean sequence, a tight group, or a staggered stream. That is why four Basic Zombies can sometimes feel more expensive than one armored target with similar work-to-critical.

ρ=λ Hto criticalRlane,ρ>1⇒backlog\rho=\frac{\lambda\,H_{\text{to critical}}}{R_{\text{lane}}},\qquad \rho>1\Rightarrow\text{backlog}
Density turns a cheap target into a lane-timing problem: the front body consumes shots while rear bodies keep walking.

Archer activation and Silver Chariot

Archer Zombie changes Basic Zombie from a low-complexity walker into an upgrade target. When an arrow resolves on a Basic Zombie, the result is either a zombie type that has already appeared in the battle or the stronger Silver Chariot state. The important point is that the target is not merely damaged or buffed; its role can be rewritten.

Because Basic Zombie has no armor, it is immediately eligible for this interaction. Armored zombies in the current build are not activated through intact armor, so the unarmored Basic Zombie is the cleanest and most dangerous recipient when Archer Zombie is present.

Letting the arrow strike a plant may sometimes be less severe than letting it upgrade a zombie, because plant transformation is constrained by the player's carried plants and a limited sun-value increase. The actual choice depends on which Basic Zombies are in the arrow line and which upgraded types have appeared.

Archer Zombie rewrites a Basic Zombie into a seen zombie type or Silver Chariot; hitting a plant follows a more constrained path.

Metal-head support and common-body identity

Magnet Truck Zombie and Sinan Kin use Basic Zombie as a body that can receive metal hardware. Magnet Truck pulls in Metal-head Zombies after it loses half its health; Sinan Kin can bestow unbroken metal heads on Basic Zombies or repair damaged Metal-head Zombies. In both cases, the danger is no longer just the Basic body's 180 HP work-to-critical window.

Read this as a layer problem. The metal head changes durability and interaction eligibility while the underlying 270 HP walking body remains the ordinary zombie frame. Magnetic removal, armor breaking, and body damage therefore answer different parts of the same target.

Metal-head support adds an armor layer to the ordinary body; armor handling and body damage are separate decisions.

Tactical reading

Basic Zombie is worth studying precisely because so many complex systems use the simplest body as their entry point. It is weak alone, but weak targets become a priority problem once they are packed together, activated, or given armor.

  • Single body: use ordinary sustained fire; do not spend emergency removal unless timing is critical.
  • Cluster: count the lane's kill rate, not individual HP; control or area effects become efficient once bodies overlap.
  • Archer present: remove Archer Zombie or clear arrow-line Basic Zombies before activation resolves.
  • Magnetic support present: treat Metal-head forms as armored variants, not as a normal body's 180 HP work-to-critical window.
