Zombie Night Terror: How to Use Spitters for Green Brain Runs

To earn Green Brain challenge badges on defense-heavy stages in Zombie Night Terror, deploy the Spitter mutation as indirect mortar artillery rather than sending your horde into direct combat. Green Brain objectives often penalize horde casualties and DNA overspending. By launching arcing bile attacks over barricades, platforms, and sightlines, a single Spitter can eliminate armed humans without exposing your swarm to gunfire.

How to Execute a Spitter Artillery Strike

Because Spitters plant themselves in place and lob caustic projectiles in a high trajectory, you must control horde movement and check room clearance before firing.

1. Halt your horde: Place an Overlord mutation behind cover or at the base of vertical access points to keep moving zombies out of enemy engagement cones.
2. Position a forward scout: Move an individual zombie into a blind spot beneath an elevated guard or behind a barrier where defenders cannot shoot downward or through cover.
3. Check overhead clearance: Inspect indoor ceilings, beams, and pipework. High-angle arcs that contact low ceilings detonate prematurely above your own units. Position the Spitter far enough back so the apex of the arc remains below overhead obstacles.
4. Calibrate and lead the shot: Drag the trajectory indicator toward the target platform or chokepoint. If targeting a walking patrol, aim ahead of their movement path at a doorway or ladder base to compensate for projectile travel time.
5. Bombard the target: Fire the acid projectile to trigger panic, splash damage, or lethal infection among clustered defenders.
6. Wait for splash dissipation: Let the lingering acid hazard clear completely before converting the Overlord back into a moving unit. Sending Walkers into active acid pools causes accidental casualties that can fail challenge criteria.

Breach Comparison: Frontal Assault vs. Spitter Bombardment

Choosing the correct breach method directly impacts whether your run satisfies Green Brain spending and casualty thresholds.

DNA Management and Positioning Rules

Spitters require an upfront mutation cost, meaning wasted shots directly threaten Green Brain DNA limits. Use these rules to preserve your resources:

• Target clusters with single shots: Most human groups succumb to a single direct hit or the resulting panic and infection, making repeated shots in the same zone unnecessary.
• Repurpose stationary units: Because a Spitter cannot walk after mutating, evaluate your stage requirements once guards are eliminated. If the exit requires all zombies to reach the extraction zone, recycle the stationary Spitter with an explosive or directional mutation rather than leaving an idle unit behind.
