	The game assigns a score to every [[Map structure#Chunk\|chunk]] in a 7 chunk radius around existing spawners (euclidean distance).

The game assigns a score to every [[Map structure#Chunk\|chunk]] in a 7 chunk radius around existing spawners (euclidean distance). Only chunks with land are considered on Nauvis, and only chunks with marsh are considered on Gleba.

	Expansion score per chunk is 1.0 if there are no structures (player owned structures or spawners) within 3 chunks (taxi-cab distance). The score is penalized down to a minimum of 0.002 depending on the number of structures nearby. The exact formula is explained in ~~EnemyExpansionMapSettings~~[https://lua-api.factorio.com/~~2.0.77~~/concepts/EnemyExpansionMapSettings.html], <code>10/(10 + player structures in this chunk + player structures 1 chunk away / 2 + player structures 2 chunks away / 4 + 20 * enemy spawners in this chunk + 8 * enemy spawners 1 chunk away + 3.2 * enemy spawners 2 chunks away)</code>. Size and cost of structures does not matter, so pipes provide an exceptionally cheap method to lower expansion chances in certain areas.

Size and cost of structures does not matter, so pipes provide an exceptionally cheap method to lower expansion chances in certain areas.

	Every 60 to 4 minutes, the game selects a chunk at random as the target for an expansion attempt, weighted by the chunk scores. Then 5 to 20 enemy units from the closest spawners assemble into an expansion group and walk to the expansion target. The time between expansion attempts and the size of expansion groups is random, but weighted by evolution factor.

	Native to the planet Gleba, stompers are extremely large, five-legged pentapod creatures with limbs that look similar to a starfish, and seem to have natural, jagged exoskeleton armor that provides high resistances to many types of damage.

Their large size and high damage can destroy buildings instantly. They will spawn premature wrigglers upon death.

FletchL1ves: Clarify Gleba evolution and spore pollution mechanics

Clarify Gleba evolution and spore pollution mechanics

			=== Space Age Changes ===
			In the Space Age expansion, the evolution factor is calculated independently for each planet's surface. Furthermore, the "pollution production" variable changes depending on the planet's native ecosystem:
			* On Nauvis, the evolution calculation tracks standard industrial pollution emissions.
			* On Gleba, the engine tracks '''spore production''' as the pollution variable.

			Industrial machinery brought from Nauvis (such as assemblers or furnaces) does not emit standard pollution or spores when operated on Gleba, meaning only agricultural tower spore output contributes to Gleba's pollution-driven evolution.

			Players can view the exact breakdown of time, pollution/spore, and nest destruction factors by typing `/evolution` into the in-game console to see the unique evolution factor for each planet surface.
