Endless mode features procedurally-generated maps of the chosen terrain. Only the most basic units, buildings and pieces start available, with the rest having to be unlocked using points. Military Capacity is upgraded with points too. There are resource caches scattered around the map but the biggest caches are guarded by Broodnests.
Progressively harder waves of enemies appear each night, with grant points when defeated. The number of directions horrors come from is random each wave but tends to increase over time.
