Very impressive work, and I can't even imagine the workload to be done (readables, dialogs, monologs, briefings, new idle animations, etc.) apart from the not exactly easy mapping with DromEd (or however that's spelled).
If someone had told me that they had been working just on Mission 2 for seven years, I would have believed it immediately. You can tell that the convoluted design of the original game was used as a reference, and I personally find it even more complex. It took me almost three hours to complete mission 2 on Expert.
I'm now in mission 3 and everything is quite bright there...thankfully the Thief AI isn't that demanding...in the Dark Mod such an enlightened mission would be very "challenging" (to say the least) and would cause quite a few nervous breakdowns!
