Awesome game, probably the best story of the series. There is much more of a human connection there, especially with Sadie's Story. But there is one thing that bugs me above all else though, why must there be invisible walls?! Especially the anti-vehicle ones along the normal gameplay route. If there is a hole big enough for a tank to move though, then I should be able to move a tank though it. If it's not, then there should be something to block the vehicle. Otherwise, it just seems that someone got lazy when developing the game.
