Submachine: Future Loop Foundation (or SubFLF) is a spin-off from the Submachine series. It was made for a band's (the Future Loop Foundation's) website, and leads you to a secret section of the website. This is probably the strangest of the games, as there is no specific relation to the other games, and has several images and music from real life.
The game features a total of 30 rooms (12 in the first location and 20 in the second).
