A really huge expansion pack, feels like it's almost as big as the main game. All the same cunning and storytelling is on display, with almost no written words either.

The only thing dinging it is, it got a bit long in the tooth for me. Every loop you have to jet back to the location of the expansion, and then you have another step of procedures to go through to navigate there, including some timed puzzles that you'll have to reset the whole loop for when you make a wee mistake. I hit a point where I more or less knew all that was going on, but still had several hours of mucking about with stealth sections and timing puzzles to wrestle with before I got to the end. It managed to make the trick of "you had the power all along!" feel a teeny tiny bit tired.

But it still tugged on my heart strings in all the right ways. Plus, it's on a spinning space colony!
