The wait is over now and GOW 3 is a reality with the first batch of screenshots out
Expert Review
Titan Combat: In simple words, you can control humongous Titans and fight against other titans, enough said.
Smarter AI: The game will put you against 50 enemies at a time, which is kind of unfair. What's worse is that once a commander steps into the field, the usually dumb AI will act smarter and attack as per his command. This leads to a very exciting proposition, wherein your primary objective is to kill an enemy commander first, so as to dumb down the AI.
Weapon Switch: The game will boast of some really cool weapons and each will be as exciting and intense as the Blades of Chaos. The coolest aspect is the instant weapon switch, so you can start a blades combo and end it with Cestus (those shiny lion-head gloves).
New Moves: Kratos can now grab enemies and rush through a large horde, using the enemy unit as a battering ram. You can also hook onto enemies and pull yourself closer to deal damage.
The game looks really promising. It's still months away from release, but what I have seen till now is good enough to make me want it real bad. This is the epic finale and the last in the series, and its shaping up very good. Enjoy the video, savor the screens and keep watching this space for more info.
