I could run up behind a guy full speed and knife him and he would never know what hit him. Also instead of pursuing you up really tall watch towers the AI would attempt to throw grenades up even though they couldnt reach. AI and limited playability aside, its a good game. Deserves an expansion pack. Gameplay is good.
Controls are easy to use and very well laid out.
Missions are a bit simple though. Needs more puzzle stuff though. Needs online multiplayer support. Needs ability to design missions and what not. The graphics i though were pretty good.
