Apparently no one else has had this problem because I have read back over the hints and don't see anything about it...I am going around in circles at the base...i have made it out of the alley but everything is a dead end. I can't go thru the northern gate because I haven't located my missing items...the admin office is no help...for the vault, i need 6 combinations and i have none....the radio tranmission building just gives me the option of inspecting and then tells me to get out...when i go back down the alley, the west door is still locked and the east (where the guards are tied up) is also a dead end...there is a space ship sitting there but all i can do is inspect it. Maybe someone could give me a little push???
