Don't think for a minute that the appearance of Switchblade II detracts in any way from this release - these are two very different games.
The original owes more to Rick Dangerous than anything else (hardly surprising when you consider that both games are by the same programmer) as it follows the adventures of Hiro and his quest to destroy the evil Havok.
This involves the player cutting a path through a futuristic underground city, battling robots and mutated monsters, searching for the sixteen pieces of the Fireblade. The whole game feels very much ike a Japanese comic-book and, as such, works beautifully.
This is definitely worth snapping up as soon as you see it, especially with the superlative sequel having just been released, it makes a nice double pack.
