Dropzone

'It's the year 2085. Only a handful of people have survived the robot wars that rocked the Solar System. In a final desperate bid for survival a Tacheon propelled star cruiser has been developed on earth to transport survivors to a new star system. But the cruiser relies on rare lonian crystals for it's power: crystals which are only abundant on Jupiter's second moon Io. A moonbase established on Io is under constant attack by aliens from Jupiter. It is your mission to escort the men and their precious crystals safely from the surface of Io to the Dropzone where the landing pad is located. You are equipped with the latest pulse-laser back-pack system which will make you invisible and indestructible for short periods of time. You must succeed, the future of the human race depends on you alone!'

There is something wrong with this game, as after a certain point the game simply doesn't continue and go to the next level.
