The game also has the final push by Russian troops to take Berlin. How does this section differ from the US Japanese campaign?

The German fighting force was a lot like our own in the sense that you found more line battles; whereas, troops would face trickery and ambush scenarios in the Pacific. You will feel a noticeable difference in play-style and enemy AI when you move between the two theaters of war.

The Russian campaign was just as brutal as the conflicts in the Pacific. The Nazis had invaded the Russian territory – burned their wheat fields, murdered their women and children – and the Russians wanted to exact their revenge, which led to a "No quarter given, no quarter taken" mentality.

What are some of the highlights in the game's single player?

The entire campaign is an adrenaline pumping, non-stop rollercoaster of trademark cinematically-intense gameplay that Call of Duty is known for. Two of my favorite examples come to mind...

The first has the player aboard a PBY Catalina – a flying boat armed with .30 cal and .50 cal machine guns. The object of the mission is to stop some Japanese merchant ships in their tracks, thus lessening the supply to the enemy reinforcements on the ground. At one point during this mission you land on the water, and have to help rescue some of your stranded sailors and pilots in the water. So you find yourself faced with the decision of "do I save this sailor pounding at the side of the plane, or do I continue taking out the approaching Japanese PT boats..."

The second takes place during the first level of the Russian campaign, called "Vendetta." The player is introduced to a Russian sergeant, Sgt. Reznov (voiced by Gary Oldman), at the massacre of Stalingrad. This mission really sets the stage of the entire Russian campaign, as you are given some back story as to why there is this burning vengeance in the heart of Reznov, and helps set the mood of the ruthless campaign to come.

What can you tell us about World At War's multiplayer features?

We are adding new kill streaks, perks, challenges, weapons, attachments, as well as tanks, squad mechanics (create, join, disband squads on the fly), vehicle-based perks, Capture the Flag, and making a return of the game mode, War.

Some 'under the hood' aspects to MP include features like: lobby host migration (lobbies will no longer close), localized matchmaking options (find lag-free games, instantly), improved party systems (party privacy, "Leave with Party" options, and anybody in your party will join your squad automatically), and our Spawn Influencer System. Our SIS is a weighted spawn system that picks where you are going to spawn based on a number of factors: where your enemies are, whether there is a live grenade nearby, whether you are in a squad, etc.
