This is one of the first batch of games from a new budget software house, Code Masters.
The company was created by the Darlings, who made their name through budget kings Mastertronic and are now going it alone.
This game is actually written by Nonterraqueous author Stephen Curtis and is a fast action shoot-'em-up featuring great graphics, addictive action and amazing sound.
The plot in tenuous, involving a robot's revenge on a team of mining engineers who must esape a hostile landscape while being attacked by hordes of aliens.
During the game you must fly your ship through a hundred screens of alien landscapes avoiding walls that will destroy you.
Built into the landscape are squares or zones that have a varying effect on you. Some speed you up or slow you down, give you extra lives and top up your fuel tanks but some are time shifts that return you to screen one. Irritating, particularly if you've reached screen 98!
The action is fast and furious with the sound of the laser sounding like a gunshot from a spaghetti western.
My only complaint is that you must select your joystick or keyboard option before every game. Pressing the fire button returns you to keyboard mode!
