9.5 great game.
Good
*Good storyline that provides closure while making you wonder what will happen next
* Four-player online co-op is a lot of fun
* Forge mode map editor kicks ass
* Web integration makes sharing new maps and custom modes easy.
* Replay function kicks ass
* adrenaline-pumping shootouts
Bad
* Rewinding and forwarding saved films can be a pest.
* AI-controlled Marines can't drive to save their lives (or yours)
* some players online are immature as other games, but when in lobby of 16 players for big team battle, can get quite fustrating.
