This is a fun little game released by Bullfrog in 1994. Internet rumor says that it was released as freeware – but I have not been able to confirm that (I am using the version I downloaded from a local BBS back in the day). The basis of this game is that you are racing a strange, car-like vehicle down a long 3D tube. The tube is filled with enemies, obstacles and interesting twisting paths.
Like most Bullfrog games, it runs flawlessly under Virtual PC (complete with sound). This game is very addictive, I found that once I had got the screen shots I needed I spent a good half an hour playing it.
