i got it and it looks really promsing, haven't palyed much yet but apparently it's really like Warrior Within should have been already, the levels and stroyline that made Sands of Time great plus the few new good stuff from Warrior Within, actually i think I will play Warrior Within again because i need to know how the story has developed to fully grasp the progress of the story, and the good thign is, farah is back!
the only funtamentally new gameplay factor so far is the speed kill system, in fact this has not much to do with speed actually, just that you have to hit the fire button in time to execute the speed kill. in a speed kill, you sneak up an enemy from behind and kill him with usually 1 or 2 strokes, depending on enemy, i really love it because it looks cool, reminds me a bit of Manhunt and most importantly, it spares you to fight out all battles the long and annoying way.
