The biters attack more often at night. This is a rewrite of Scary Nights, but runs far more efficiently: The CPU requirements of Nightfall will not increase with map size/play time.

Please take note: this mod respects pollution. In a large starting area, it may take a long time before pollution reaches biters, especially in a forested area.

Compatibility with Other Biter Mods

Nightfall should be compatible with other biter mods. This mod does not touch the inner workings of biter AI, but simply requests the AI (whether that's modded or vanilla) perform additional attacks.


Found under the Settings -> Mod Settings menu, an experimental feature has been added that suspends biter attacks during the day - so the only time biter attacks will happen is at night. This may cause compatibility issues with other biter mods - if in doubt, leave it turned off.
Further warning: Biters will still build up their forces during the day. Night attack waves in this mode may be very large.
