The Good: Incredible visuals and graphics; awesome environments and settings which are totally interactable (you can pretty much move, destroy or use anything you see); there are enough weapons to keep you happy and they are all extremely satisfying to use; the controls are very practical and easy to learn; the AI is one of the best - if not 'the' best - I've seen in an FPS (the enemies actually take cover, try to flank you and respond to your tactics); the puzzles you encounter along the way gives the gameplay a really nice touch; it has an amazing story line which is easy to follow and keeps you interested throughout the entire game.

The Bad: The airboat segment is way way way too long and sometimes it feels like you're lost and don't know if you're going the right way; the frame rate is exremely irratic and sometimes it just dies; THE LOADING! OMG! What is up with all the loading!? It stops to load in the middle of gameplay every 3 minutes; half way through the game you may feel like you have barely killed any enemies; there is no multiplayer.
