We've had mixed experiences with Lockdown, depending on the room.
Chem Lab: this is a well-done room. The puzzles were somewhat challenging, but very creative, and the room's décor was really spot on for the theme. Everything worked well and it was a very enjoyable experience for myself and my husband.
Samurai: despite being a beautiful room, the puzzles need a lot of work. Many puzzles were primarily electronic/magnetic (?) and need to be re-calibrated. Even when things were lined up properly, it wouldn't work and the game master routinely had to tell us to "move things around a little bit" in order for it to work. The game master also had to chime in again before we even started doing another puzzle in order to tell us how a puzzle worked. It was a pretty frustrating experience.
Heist: this room was okay. The décor is straightforward and a little bland. The puzzles all worked, but weren't necessarily creative or unique.
