Undertale Fighting Game

March of 2022 to May of 2026

Undertale Fighting Game

My very first project! A roblox multiplayer fighting game where players fight eachother as various Undertale characters. This game achieved over 6 million visits and over 2 million unique users.

This game was programmed in LuaU, a form of Lua for Roblox, and built in Roblox Studio. It started as a passion project between me and two friends and after about two years of updates, the game exploded in popularity and in the span of a couple of months went from about 10k visits to over a million.

Timeline

Game Creation (March 2022)

During the creation of the game, I was started learning to code and ended up creating the games first character, however the quality was not the best...

Pre-Alpha (October 2022)

After several months of work the game had 7 characters, a main menu and was released in pre alpha to play. However, we realized the game was still in development and needed to be improved so we decided to step back, delete some characters, and completely rework the game.

Betty Update (May 2026) and Hiatus

During the 2025 to 2026 school year me and the other developers were extremely busy with school and other responsibilities so we decided to pause developement on UFG. After exam season we delivered the Betty update which added a new character and the games first skin. Now the games developement is on hiatus for the forseeable future depending on the situation.
