A very well constructed two level solo map that will have you retracing your steps many times. No terminals, not a whole lot of detail but some great ideas along with some very good construction. This author has come a long way since his first map and make sure you take the time to send him some email. I was stuck forever on this thing before I finally found my way. It is possible to finish so keep trying and make sure that you explore EVERYWHERE. The second level is really just the end so once you get through the first, you are practically done.
