I'm kinda shocked it didn't get a 10 for graphics.. this is easily the best looking console game to date... but not a system seller
Here is the summary:
9.5 Presentation
Everything from the first entrance onto the battlefield to the last cutscene creates a hectic, fun and fast-paced thrill ride through a warzone where each step you take could be your last.
9.5 Graphics
Phenomenal visuals prove that Guerrilla either met or surpassed that infamous E3 trailer. Some technical issues hold it back from being a completely flawless masterpiece.
9.0 Sound
7.1 channel sound captures every nuance of the battlefield from gunshots to screams along with a great soundtrack. Weakly delivered, curse-filled dialogue (sans Brian Cox) could've been done better.
9.0 Gameplay
You'll have to get used to the firearms as well as the AI on both sides. More turret and vehicle sections would've been great, but outside of that, the single-player campaign is fun to play through.
9.5 Lasting Appeal
Multiplayer is extremely deep and has the added bonus of an offline skirmish mode. This is where you'll spend the majority of your time once the credits roll.
9.4
Outstanding OVERALL
(out of 10 / not an average)
