Factory

Factories are buildings that may spawn additional enemies. They may be live/lit or dead/dark, with live factories potentially spawning enemies and dead factories being harmless. Once the maximum number of factory spawns has been reached ALL factories will die. Factories that have hit their spawn limit may continue to be lit but are otherwise harmless.

Factories are the only building enemy type and also the only enemy that does not do damage on contact (technically Good Robot passes over them). Once killed they will explode; this does cause damage if you are in the explosion radius.

Spawn Logic
Enemies that are not spawned upon entering the zone will be spawned from Factories. The logic dictating if a factory will spawn an enemy is:

- if the player is near the live factory, AND

- has line-of-sight to any part of the factory, AND

- the number of alive, factory-spawned enemies in the zone is below the threshold, AND

- the factory has not exhausted its own spawn limit, AND

- the zone threshold for factory-spawned enemies has not been reached, then spawn.

Point Farming
Destroying a factory nets no points and may reduce your potential points if the zone has not hit its factory spawn limit. If you destroy the last live factory this will stop any new spawns thereby reducing the maximum number of enemies in the zone and thereby reduce your maximum potential score. Not destroying any factories ensures the highest enemy count in a zone. New enemies will likely be huddled together, which also makes it easier to keep your point multiplier high. Enemies do like to hide 'behind' factories so not destroying them while attacking enemies can be tricky, unless you draw them away from the factory.
