Tube

Tube is a very cool demo / freebie / thing created by a programmer at Bullfrog Productions and subsequently released for free on various old PC gaming magazine disks. The included text file is rather confusing since it explicitly states that this is "neither Freeware nor Shareware" and that it shouldn't be distributed but then says it may "only be passed on chargefree via Online". So anyways, this is a 3D perspective racing / action / shooting game, although it's more of a demo than a game. You race forwards, move, shoot, and admire the smooth-scrolling backgrounds, loops, and other cool stuff going on. A fun experience, at least for a short amount of time!
