In the not too distant future, it would seem that a race of aliens calling themselves the Durrs (they sound a bit spoddy to) will land on the Earth and, in a remote spot, build an atmosphere processing plant. With this they plan to bring about another Ice Age and thus destroy the human race. How unpleasant.
A-ha! But not if Lance Gryzor (ie, you) has anything to do with it! Lance (crap hero's name, that) is a member of Federation for Earth's Defence who has to infiltrate the five levels of blasting action and reach the Durr stronghold before they have the chance to switch their machine on.
Aliens are not to be taken lightly, though - they send in plenty of henchmen stop our square-jawed hero. Though his weaponry is limited at the start, there are collectable weapons along the way.
As scrolly blasting games go Gryzor isn't too bad, although the monochrome sprites are almost invisible against some of the garishly coloured backgrounds (very irritating). Be prepared to apply for your Spectrum's pilot's licence: the enemy hordes are pretty vicious and take a lot of practice to get past and will have you chucking your Speccy out the window in frustration. In short, Gryzor is probably for people with milder temperaments than mine.
Mr Gryzor now plays hide and seek in a 3D maze section.
Here's Lance performing a triple somersault backflip with half pike as he attempts to evade the evil henchmen (and fails miserably).
