I'd disagree with you there guys. I just decided to try this game and I'm sort of enjoying it.
One of my biggest concerns is that I'm unable to heal, and that the text size is really small I have to lean in to read it, as well as the fact that there's no save function. Really gets tiring and your eyes hurt eventually trying to make out font 5 letters, especially if they're on a same colour background.
I don't see anything wrong with the AI. They're just like anywhere else. Sort of like Half-Life 2 style, with some improvements, I'd say. At least they manage to strafe, they run in the right direction, actually take cover (!!!) and like to gang up if possible. I'm far from seeing this in AAA titles.
The levels are awesome. Whoever was the artist on board, he's one of the best. The whole idea is actually far from being Deus Ex, it's a huge setting with beautiful ideas. Samurai-style space monk-warriors with lots of vivid technology, firearms (strangely) and cool katanas? This is a great idea.
If they release a patch increasing text font, tell me how to heal, fix some grammar mistakes here and there, and add in a save function, I'll be happy. I agree that respawning enemies are quite a bore, but I can't really complain I guess. There's an option to cut down enemy reinforcements, so I'll go with that.
