Solid expansion to a great game!

It has all the same positives and negatives as the base game does. This is just a slightly smaller campaign with a few new mechanics and a new narrative.
The most interesting new mechanic is memory analysis, which sort of lets you download an image of the machine you have accessed to scan its memory for information. This is somewhat contrived and ends up being the thing you do once you exhaust all other options, but it is still kind of interesting and feels sufficiently hackerish enough to be fun.
There is a much-needed addition of a network managing tool. It only occurs near the end of the expansion, unfortunately, and it still doesn't make things quite as usable as I would like.

The narrative is a bit less directed in Labyrinths, with most of the missions being done for pretty unclear or unconnected reasons. This isn't a huge deal and it does come together in a tense and fairly panic inducing final mission that I liked quite a bit, even if it didn't have the most motivation.
One other standout mission has you messing with files on your actual computer, which is a cool way to make things feel more immersive and cool.

Just more Hacknet, which is a good thing. I wish it had a few more curveballs or meaningful additions to the gameplay, but it is worth playing along with the base game!

A short and sweet follow up to Hacknet, the Labyrinths DLC takes you on an all new adventure as you join up with an elite crew of world famous hackers who want your help to perform some crazy hacking heists.

The story is quite short and the gameplay is a bit different than the core game as it adds some new tools to your arsenal and presents you with all new high stakes hacking challenges.

If you're a fan of the original game and the main story left you wanting more, this is a perfectly fine follow up from the original author - but by all means expect more of the same for the most part.
