OLD ULC SANDBOX
A Roblox experience owned by Undertale Modded.
Description (written by the developer; not a statement by this register)
This game is a fan made version of the original ULC. Everything here isn't ours. But everything in the game is free. We will be adding custom characters, weapons and more stuff soon! This is NOT an official version of ULC, game ownership was transferred to another owner, this is not the official version. (Game most likely isn't getting music since i don't want to get into any copyright trouble since i wouldn't have any permissions due to obvious reasons.)
