If I had a fiver for every version of Centipede I've seen... There are cacti instead of fungi, and cactus spores replace fleas; but the spider remains - and a bonus lizard is thrown in for good measure. Elimination of a string of red scorpions merely summons up a replacement along with another batch of cacti, both with altered colours.

Each version of Centipede has attractions and minor differences: an almost bewildering selection, in fact, and I can't imagine any shop giving a demo of all they might stock. If you like the scenario this version should not disappoint you. But be warned - sooner or later it's always possible to find another variant that may appeal.
