Yet another Uridium clone and not a particularly good one either. Erebus is a planet developed to take care of the Earth's waste and turn it into useful gases and chemicals. These processes are automated and require only occasional maintenance. But trouble starts when missions from the inhabitants of Hadebus visit Erebus. The Habeans are bitter enemies of Earth.
Investigations reveal that the Habeans are altering the processing operations to produce a deadly nerve gas and it doesn't take a genius to work out who is the intended victim. It is up to you - having been sent to Erebus - to eliminate the invaders.
The planet is oddly constructed. Consisting of several circular levels, each level is split into eight zones surrounding a central duct. Each of the zones must be visited in turn, blasting as many Habeans as you can en route, before the central duct opens allowing you to drop down a level. Each sector is scattered with solid structures that cause you to crash on collision. After you manoeuvre yourself into the duct, you get the chance to take part in a thirty second bonus screen in whch you must destroy as many of the baddies as possible within the time limit. Then it's on to the next level.
If the plot sounds *too* familiar, it's because it is. Although there is nothing wrong with that, you need some pretty spectacular gameplay and graphics to make it stand out from the crowd. Erebus doesn't have either and the result is a totally uninspiring game.
