I played the demo and was hooked! Really cool concept to do a FPS without the shooter. It starts out with a great opening. Graphics are great with a new look to normal games. Instead of trying to make things as real as possible, it throws you into a high contrast realm with real vibrant colors showing you the path.
The controls take some getting used to, but that's because it's a new style. Kinda how Skate changed classic Tony Hawk controls to a new, dominate way to play.
But not everything is perfect. You fall or die ALOT. I fell about ten time before realizing I need to scale a wall. The fight controls a hard to master as well.
Another thing that let me down is after seeing the glorious opening movie and trailer to the game, all the cut scenes are crappy animation, Might not be bad to all, but "a taste of honey is worse than not at all." Meaning the opening movie spoils you.
Over all the game is fun. I consider it a rental, but a good one at that. The replay vale won't be up there. It is a must to play! And you get to check out hot chicks that run alot!
