As an introduction to Robot Knight you are given a history lesson to explain the task ahead - quite good reading it makes too.
The villain of the piece is Otto. Living in a serene and easy-living Futureworld, he constructed his evil plans for world domination. His plot, however, was uncovered and he was thrown in prison. But it wasn't long before he hatched an escape plan.
Feeling bitter and twisted that his penchant for famine, disease and poverty wasn't appreciated in Futureworld, he resolved to go back to a time where these qualities were a daily fact of life.
This was not Maggie's Britain in the late 20th century, but Europe in the 13th.
Finding an isolated chateau, he built a laboratory in which to perfect the ultimate being, to unleash it on an unsuspecting Futureworld.
So far he's met with only limited success and zombie-like rejects roam the lower reaches of the chateau, deterring all but the most hardy of double glazing salesmen. It is your task to find Otto and destroy him before he perfects the final monster.
You materialise in the chateau and must battle through various dungeons and chambers, past the skeletal zombies and their fireballs, collecting energy packs on the way.
The ultimate goal is Otto's laboratory, where the monster is about to awake.
Essentially a platform game, Robot Knight has a feature which makes the game much more interesting. When starting you have a choice of two knights.
Either knight can be used in a one-player game. In a two-player game, both are used simultaneously and you can choose to act as allies or enemies.
It is the rather fun two-player option that lifts Robot Knight out from being just another platform game. If you play your computer games with a friend, this would be a good buy. If not, I'm sure it's still sufficiently tricky enough to appeal to some.
