Spitter

The Spitter is an environmental hazard which will inflict infection and a small amount of damage when triggered. They cannot be killed, but they can be temporarily neutralized.

Appearance
When active, the Spitter is a grey-colored sack with smaller green bulbs filled with a blue, greenish liquid. These bulbs will glow brighter as a player comes closer to them. When inactive, spitters are smaller and lack the bulbs.

When exploding they will glow bright, as a similar colour to the bulbs.

Spawning
Spitters only appear in certain rooms in certain expeditions, usually those with higher levels of infectious fog. They can spawn on almost any surface and they also appear in different sizes.

Behaviour
Spitters have 2 different states which determine their behavior.

Inactive
When in this state the Spitter is completely incapable of harming a player. They enter this state when they:

1. Have a flashlight shining on them (inactive for 30 seconds)

2. Explode by either shooting, melee attacking, or proximity to a player (inactive for 35 seconds)

3. Become C-Foamed (inactive for 4 minutes)

Active
When in this state the spitter is dangerous as it can explode when a player gets too close to it. When a Spitter explodes they will inflict direct damage and infection onto any players within range. The amount of infection depends on the player's proximity to the Spitter.
