The scenario is pretty standard. Take a couple of space ships and put them in an Asteroids-type arrangement.
Chuck in a few aliens, rocks, black holes and monoliths and make the game easy to customise and you've got it.
The aim is to simply slice up your opponent and anything else you find.
The nice touch is that you can set up the game to suit your own preferences. All parameters are adjustable: speed of ship, fire rate, inertia, how many aliens and gravity effects are just a few.
While the overall game instructions are minimal, the instructions for parameter changes are excellent.
An action freeze option is available if you want a rest during your game.
Graphically, the game is adequate, but not mind-bending. Explosion effects were particularly banal.
There are options for both joysticks and keyboard or any combination thereof.
Not my idea of a great game, but arcade freaks should give it a look over.
