soulgrindr: I loved this game when i played it.
Good atmosphere, looked good, good controls, very tense and required some thought.
I'm not sure why everyone keeps saying it was hard though, i don't remember it being particularly tricky. Sure, for each level there is a "correct' solution, but it was usually pretty obvious. I didn't find it half as hard as some obscure puzzles in adventure games, for example.
Strangely, though i really enjoyed it, i never got the urge to play the expansion pack or the sequels. I think it's length was about perfect, so i was ready to move on.
Agreed, a great atmosphere, a nice art style for buildings and maps in general.
The game is not haaaaard. Personally, it was hard back at the days because i was young.
Yes, the objectives are displayed pretty obvious, with in-game introductions of what to do in each mission, for those that aren't good at RTS, and you still can play in your own style to achieve the objectives, playing more stealth or action, or even avoid the enemies, as you like.
