Just finished it last night,I didn't have high hopes with the surrounding hype etc,but was pleasantly surprised and found the story quite engaging,graphics look very nice,even on my mediocre latop.
I particularly liked how the game didn't turn to crap towards the end like most FPS do,yknow.......we've run out of ideas,so we'll just throw more and more baddies into the fray.
I usually get bored with FPSer's that the whole game is played inside [doom3style] but this game is unusual and different,and I think the makers should be commended for adding a bit of variation with weapons,plasmids,powerups etc.
Only thing I can say bad about it is that it seemed to be very difficult to tell which direction sounds were coming from,like it was in mono or something[it wasn't]
And I only had one crash back to desktop in the whole game
i enjoyed it immensely. and i think that sound origins was done intentionally.
