SporeWithin

Hidden carrier vessels and decaying remains form subterranean mounds that act as defenses and build a seven-day race against the Hivemind. Mounds within 250 blocks link into pairs and divide responsibilities, while an Incubator shares intelligence through underground mycelium and directs partner player positions. The Aggressor works as the front-line hunter, sending out a steady flow of stalkers and patrols and launching siege attacks.

Mounds send out mobile patrol squads that orbit base perimeters and react to player footsteps or block breaking nearby. Scout Stalkers follow players at a distance to observe defensive layouts and inspect chests and doors, avoiding direct combat. Scouts that gather reports sprint back to a mound, and delivered reports let the hive plan targeted base sieges. Wiping out a scout party sets off a distress screech that rouses neighboring nests and draws them into raids.
