Play this mission only if you are interested in the history of early era FMs. Otherwise, it's a rather poor mansion level with a lot of bugs (the mission cannot be finished unless you install a .dml patch that you can find on TTLG forums; I can imagine it was totally broken back in 1999), lazy design and object placement, uninteresting readables, broken lighting and roombrushes. I wouldn't say it's the worst mission I have ever played, but if you want to play some decent mansion heists from 1999, I can recommend Torben the Traitor, Circle of Strain, and Lord Edmund Entertains.
