Highly enjoyable overhead perspective blast fest with the controls well suited to the spin and shootin gameplay. Time is of the essence as the player plants a bomb at the start of each level: just as an insurance policy. These sort of frantic shooters are a rare breed these days - perhaps the genre was taken as far as it could go - but theres certainly an arcade thrill to be had from rampaging through the Geiger inspired alien hordes with a souped up weapon to free the homo sapien hostages.
