I found the opening few scenes to be busy and confusing, but this laid the groundwork to establish a good cast of characters for a very good adventure.

First of all we have new companion Mathew Sharpe, he appears already in the TARDIS having completed a number of adventures which are mentioned in passing, while his background and meeting with the doctor is told in a flashback later. This is a simple and elegant way of bringing him in. He also makes quite a good companion and I thought far better than some of the other new companions introduced by Big Finish recently.

The setting has a lot of back story which is discover as we go. The doctor has to piece things together but we also learn some critical things from the supporting cast.

In terms of the story, it works well, going from introduction, discovery and initial threats, evolving into murder mystery, followed by base under siege before the greater threat is revealed and we get a stunning cliff hanger at the end of part three that makes everything to this point worth while.

That was a slog to get through.

This last batch of releases for the 6th Doctor have been really disappointing. It doesn't help that he has been saddled with two of the worst original BF companions. Flip is just Lucy Miller lite and nowhere near as well acted and Constance Clarke is a dull character portrayed badly. On top of this there was just a multitude of bad acting by nearly all the guest actors. Truly one of the dullest releases to date

Some descent concepts but the music is a bit cringe and there’s few surprises. Still a easy listen 6/10

It may have been a mistake to get a Torchwood writer to tell a UNIT story. This does not feel like a UNIT story. There are only two UNIT officers in it anyway. There is no continuity with any previous UNIT officers, so it just feels wrong.

The whole thing seems to move very slowly with the first two episodes struggling to tell one episode's worth of story. The stand-in companion is fairly uninteresting.

There is not much to the story. The doctor is looking for aliens and finds UNIT also looking for aliens and someone else has found the aliens and nobody trusts anyone else.

There is a nice revelation in part 3, there are some nice moral questions being asked, though not being argued very well and simply not much else to recommend with this release.
