This was a fun and well-made take on the base under siege type of Doctor Who stories. I liked the characters and the danger that the Cybermen presented themselves without it relying on sheer numbers but rather just having their threat carefully built up over the course of the audio. Charley and the Doctor were both great here, but I enjoyed Deeva's character too. It really felt like they did a good job with giving her a bit of a redemption arc without dragging things out too much, either. Overall I think this is a nicely balanced Eighth Doctor entry, even if it isn't the most memorable story in the world, either.
