THE LEVELS OF NEXAR
So, you have ignored our warning.
Very Well!! Upon presentation of your encoded identity cartridge you will be sent to the entrance of the space warp.
At each level there are RADIOACTIVE BEACONS that must be destroyed. These BEACONS are guarded by impact exploding SAUCERS which guard the BEACONS.
