No_exit_cave.exe (In The Caves) throws out the normal overworld generation and replaces it with a single, infinite cave system. There is no surface, no sky, no way out — you spawn underground and stay underground.

Features

• Fully custom world generation: endless connected caverns instead of a normal overworld
• No surface layer exists — this is a one-way trip down
• Built as the foundation for cave-only survival and horror-style gameplay

Requirements

• Minecraft Forge, 1.20.1
• Requires Cave Structures (InTheCavesStruc) — without it the dimension has no settlements/structures and the mod is not meant to be used standalone

Compatibility

• Forge 1.20.1 only
