ASTRO BUBBLE 2: 683's REVENGE - Sir, the "ASTRO BUBBLE" project is little short of failure. (Specimen) ¹683 ran amok. - Sir, it is going in here! Green mass entered the laboratory complex with loud brattle. - Proclaim total evacuation! Turn off the refrigeration! Block him up! The sirens began to ululate in the corridors: - ATTENTION! It IS NOT A TRAINING ALERT! THE VOLCANO UNDER THE COMPLEX IS NOT STABILIZED! ATTENTION! As you have already guessed, 683-rd - is you. You have to get out of the laboratory complex where you were created and which already became empty. To open the exit, gather the crystals. Be careful with lava and lasers. Sometimes to turn off the laser or to discharge lava it is necessary to push the button which you have to gain before it. But it is worth while. Onward to the freedom!!!
