Realtime's second game, following their popular Tank Duel is another wire frame 3D game, set in space. This is one of the new generation of wire frame games for the Spectrum with fast moving coloured graphics. There are basically three different screens to play through, linked with computer 'tacticals' and culminating in a grand 'finale' scene. In the first section you are in the furthest reaches of space, fighting numerous alien fighter craft which hurl powerful plasma bolts at you. The object is to destroy as many enemy as you can by firing at them with the twin lasers, but it is also essential to destroy the plasma bolts as well to survive.
The second screen takes place on a battle planet, covered with a variety of towers. Some of them are armed, indicated by their yellow tops, and these also fire plasma bolts at your craft. Surviving through this screen takes you onto the third, and down into the trench. The trench has laser blisters on its side, which fire at you. Again it is important to destroy the bolts as well as the blisters. The trench is criss-crossed with transverse bridges and side towers, which must be dodged by weaving in and out of them. At the end of the trench is a protective forcefield, through which you must fly. But to disable the field, the two rotating cubes to either side must be shot out of the way. Failure to do so, will result in your being forced back into the trench again. If you get through unharmed, then you are shot into space and you see the planet behind explode, before going onto the next difficulty level.
The screen shows the status panel of your craft with the view beyond. The instruments show shield status and laser status, levels and score. The lasers overheat rapidly and take time to recharge. Shields are damaged by hitting enemy craft, towers, trench walls etc. as well as the enemy plasma bolts.
