Unity was a shooter/music game by Jeff Minter (Llama Soft). It was cancelled, after approximately two years development, in December 2004. Unity was being made for the Nintendo Gamecube, and was gaining quite an interested following. The game would have seen release quite late in the system's life,
Unity was built concurrently with (or, it is perhaps more accurate to say, on top of) Minter's Virtual Light Machine (VLM) 3, which would be later developed further into the XBox 360's visualiser Neon. The VLM was used to create the environments, and enemy patterns based on the music.
