With a plot to enslave the entire galaxy, the evil Dargons must be stopped as they invade ours! Dargon Ringworlds (like a planet on a spaceship) are sent into conquer populated worlds and then use them as a base to conquer other worlds. You have to stop 'em quick before they take over every ruddy planet!
Ringworlds are destroyed with a photon torpedo. Then, to liberate an occupied planet you have to capture a shooting star and steer or tow it towards the planet. Release the star onto the planet and it destroys the Dargons and liberates that world. Oh, and there are loads of alien thingies all over the place to shoot too.
Gameplay is essentially an eight-way scrolling shoot-'em-up but with a yucky 'intellectual aspect' thrown in. There are billions (quite a few -Ed) of dials to keep an eye on and to succeed must be followed correctly; the status panels (on the left and right hand sides) are continually blasting you with information which takes away most of the fun you might have in carelessly blasting everything! Solar Empire is a funny mix of gameplay - you want to play it fast and furiously, when you should be playing it a bit strategically. Except you can't play it at all on the +2A, because it's not compatible.
