This movie is based on the game called Lemmings. For those of you who don't know it, and should be ashamed of it; Lemmings is about controlling little "people". You assign them different tasks to complete levels.
The song is called Evolution 169 and was created by Nevermore.
Btw, there's a hidden movie in there! I didn't think it was worth it to submit it separately so... Good luck finding it :)
