This mission is overall well designed. Not the biggest one, but packed with several places you can visit. Climbing can be helpful but isn´t needed to finish it. It has some custom recorded dialogues which are are also of good quality.
The backstory is ok - while not a masterpiece it serves the setting to hear the dialogues or read something about the newly formed order of the Mechanists. Number of writings is enough, I don´t like missions which have tons of texts that doesn´t add much to the gameplay, and good thing this isn´t one of these.
Difficulty is not too high - it´s rather a no frills mission than one with tons of riddles.
Sometimes it is a bit frustrating when objects are just there for decoration and not frobbable, and some doors are dead ends.
Anyway, I would recommend it.
