Whenever I see a fan mission crafted with such efforts like Eclipsed, I really hate to point out how the end result as a whole ultimately falls down. Mostly, because it is quite clear from the very beginning that the creator had a fantastic vision. The map is shone by its beautiful colors and architecture. Then - after you passed the first (completely linear) section - the issues start to become shockingly obvious...

I'm pretty sure, most of the more experienced Thief players have a tendency of exploring a map as much as possible - climbing on everything they can, etc. Well... this mission was clearly not made for them, because the architecture is filled with sometimes unreasonably not climbable ledges, weird, invisible obstacles - but then when you manage to awkwardly bypass them, you easily end up in places you are clearly not supposed to be. In fact, climbing out of the intended areas is easier than following the annoying keyhunt backbone of the whole mission.

Let me tell you one of the more extreme examples: you need to find a key to an area which is blocked by a gate. It is actually pretty easy to climb on the rooftops planning to just bypass that gate - but when you do so, you have to realize the area is disabled if you do not enter it in the intended way. What else can the player think about that other than it is an arrogant design choice?

I'm sure and understand there are players who aren't get easily annoyed by aspects like these - and can enjoy the mission for its better qualities. But for those who have a critical sense, I can only recommend to rather avoid Eclipse, unfortunately.
