A Roblox experience owned by UT Battle Engine Fanclub.
Description (written by the developer; not a statement by this register)
[IMPORTANT] The game is designed around an external asset loader to vastly improve loading of images, higher resolutions, more sounds and music, etc. It is not required to play the game but you may miss out on the custom fonts and crisper images, as well as having images flicker as they appear in game. The asset loader can be found in the communications server, and is completely open source. An in-depth explanation of how it works can be provided upon request. /--------------------------------/ Undertale Battle Engine (UTBE) is a 2D recreation of the Undertale engine in Roblox, with online multiplayer and various other things.
