Welcome back. We have a serious proplem. In our attempt to stop the allien robots from ever attacking earth, we failed. We sent delta force down but lost contact. We have re-gained contact with delta force's scientist, he is being help captive. We need you to go in, rscue him and get out. You may find supplies from delta force. Oh, one more thing this will be a solo mission, we'll try to keep in contact but till we see you =, allive again, your on your own ....
