# Railway corridors [`tsm_railcorridors`]
MineClone 2 adaption. NO TREASURER SUPPORT!
* Current version 0.12.0
* Current version 0.14.0
Minetest mod for adding underground corridors with rails and wood constructions with
a few treasure chests now and then. Optional Treasurer support is available for adding
treasures from various mods.

## Info for modders
Want to include this mod in a game, but you hate the dependencies?
You can edit the node names in gameconfig.lua to fit your needs. :-)
## Info for game makers
