Here is my definitive rating after my solo game.

The hook is correct (can be improved to make it more visceral) and the reward is attractive! The well-known scandal ("latest scandal") about the opposing organization makes the investigation much easier. 

The investigation phase is also made easier for the PCs and the GM thanks to "Mazes Secrets" to be collected through RP/social engineering which can be great moments. It is important to encourage players to carry out their investigation and scouting before planning the break-in, otherwise an assault could easily turn into a fiasco when faced with a real safe. The maze itself is quite nice, with a favorite being the “Drone Traps” and the “Random Encounters”. 

As for the final boss, very good reinterpretation of a classic! Finally, at the end of the scenario, I found it interesting to add some randomness which made the sponsor a little bastard despite the circumstances which should have made him someone grateful. A little extra spice.

 In conclusion, even solo there is really a way to have fun with this great scenario, which I can't wait to play at my table !!!
