About this project
What does Slendytubbies: Dark Horizons add?
This Mod Is In BETA! Much More content will be added, AND changed over-time!
6 - Different newborn types spawn at night.
15 - Summonable Bosses.
7 - Different Structures.
C.O.A.T Patented Audio lure Technology:
"After a significant number of our living assets escaped containment, we developed a new highly configurable device that attracts them to US instead of wasting company funds on search and recover operations"
Craft boss summons by first crafting a C.O.A.T fuser and an audio lure. Then place the audio lure in the top slot, and genetic material in the bottom slot. Audio lures can be crafted, and different genetic materials can be found in the mod's structures.
This mod is based off an AU i made a while ago, and i had decided to repurpose some of the designs i made for it for this, so there will be a few redesigned characters here and there.
