This is an important audio in that it is great for establishing some character to our UNIT crew before things go nuts in the following audio, The Longest Night. On its own, though, I found it a very standard story that didn't quite stick with me the way some of the later UNIT audios do in this particular range. I just found the Southend characters pretty standard in terms of what we might expect out of Big Finish, and I really didn't get much out of the conflict of the story, either. Still worth listening to even if it is just to get the full UNIT experience of these early Big Finish audios, and that's a good thing, even if on balance, I found this to be the weakest of these early Big Finish UNIT stories. It definitely feels like over time, the company was able to take the UNIT brand into a more distinct direction.

Also, as an aside, you absolutely should be more familiar with UNIT in general in addition to listening to both the Coup and Time Heals before seeking out Snake Head.
