I'd by that for a dollar! Or 5, as the case may be.
The gameplay was always it's strongest point, easy to grasp and harder to master. Running backwards into corners and trying to sidestep mines whilst you're mowing down hordes of uncomprimising bat wielding thugs, doesn't come much more satisfying than this. Ample power-ups in the form of firepower and defencing rings etc gives the game extra spice. Grenade launchers, rocket launchers, "shotgun"-i suppose-(fired out 3 shots in a wide cone) and defensive tools like the rings of death, allowing you to run into large groups of enemies and cut their heads off, all contributed to keeping a strategic element alive within the mass of button mashing.
As simple as it all sounds it really does test your hand-eye-coordination, especially towards the end. Rooms become a sea of enemies, and decision making skills are a must, no time to dillydally here.
