The story, graphics and animations are all spectacular. This game has all the right elements to draw the player in. It makes me feel like the series will only get better.
That being said, some of the controls could use some work. Using the mouse wheel to switch between weapons caused the screen to scroll as well, and sometimes when I used spacebar to switch between modes, it caused me to go back a screen. Also, when moving the mouse to the Select All Characters button, the screen movement means I can't select the people. I don't know whether some of those are interface issues or my browser, but they do make the game a bit frustrating. Clean those up, and the next game will be perfect.
