Rex the dinosaur is fed up of the environmental damage being done by a nearby nuclear plant. As a result, he takes to the heavily-guarded tunnels that lead to it, with the intention of ridding the world of nuclear power forever.

The game is viewed from the side in a flick-screen format. Rex jumps and shoots, staking out various walking and flying enemies. Walking on to a Beam Pad means that upon losing a life, you will resume from the screen on which you died. As enemies are dying, keep shooting at them to keep increasing your score.

There are power-ups to collect, through energy bubbles. Each weapon has 5 possible energy levels, and can only be used if you have enough. Collect a bubble when you weapon is at the top level and you will collect an improved weapon.

The Light, a fictional company

The Light was a fictional name for the real company Creative Reality. The respective members used the following pseudonyms: Jason Austin (as John Anderson), Neil Dodwell (as Neil Harris) and David Dew (as Richard Allen).

The Title: Rex

For the majority of the game's development, it was called Zenith - the tower Rex is tasked to destroy. But it was decided this might cause problems because of a well known UK double glazing company. So the name was changed to Rex.

Rex's Taxonomy

Despite his name and appearance Rex is not a descendent of a Tyrannosaurus rex, neither a member of the Superfamilly Rhinocerotoidea. Actually Rex is a Rhinoceroid sapiens, an ancient bipedal race of mercenary aliens which look like Rhinoceros.

C64 version

Although a C64 version was planned, David Martin of Martech confirmed to Retro Gamer in 2014 that nothing was ever started, due to the company attempting to focus on the ST and Amiga from then. Despite this, the game is advertised in the C64 reissue inlay for Spindizzy, probably in error.
