Mod «Darkest Night SK Steam» for Rimworld (v1.3 - 1.4)

This mod adds new hidden faction 'Darkness', and therefore cannot be added & removed from existing savefile.

This mod adds several hours long event: all unlighted places will become pitch black, and invincible Eldritch horrors will arrive to prey on living humans, trashing unprotected electronics and doors in search of opportunity to catch colonists off-guard. They can only stay within darkness so colonists must protect themselves with nearby light source until the end of Darkest Night.

'Permanent Darkness' condition can be further tweaked on mod settings to make Darkness appear only when the sun is down.
