This budget re-release, originally from Durell, has nothing whatsoever in common with the vomit-inducing Diana Ross ditty of the same name. Well, perhaps it does. They're both dire.

Some Green Party member has gone and dumped eighteen radioactive canisters throughout a seven-storey nuclear treatment plant, endangering the lives of all the staff who work there. Not very environmentally friendly, wouldn't you agree? What's more is you have thirty minutes in which to collect the canisters, make them safe and combat the robot security system which has, purely by chance, gone haywire.

Chain Reaction is a particularly awful piece of software. Pathetic, chunky sprites, gaudy colour and a lack of anything to do other than collect the canisters results in a game best buried in concrete tomb for the next 10,000 years.

Awful colour, ineffective 3D and dull gameplay make Chain Reaction one to miss.

Mainly monochrome, with just a hint of conservatively-placed colour. The game is still a pile of old waste matter though.
