Tube

Tube is a little known game from Bullfrog which, according to Home of the Underdogs (see links) was originally intended to be a test for a new Bullfrog employee.

A unique concept in itself, Tube utilizes an old demo trick to simulate an endless forward-moving tunnel, along with some neat vector effects to simulate a long race track of sorts. In a nutshell you have to pick up speed in order to beat the track before your time runs out; you also have to destroy various obstacles in your way and collect weapon upgrades.

This game was never made into a title by Bullfrog and was released on cover CDs of various magazines. Each mag got its own unique variation: the logo of the respective publication appears as a wall texture in the game. Publications featuring the game included: PC Gamer (UK) published by Future Publishing in issue 19, June 1995 and in PC Player (Germany) from DMV-Verlag in April 1995.
