Call of Duty 2: Big Red One
A few weeks ago I got to play Call of Duty 2: Big Red One while meeting with the good people at Activision. The game is entirely new, meaning a new core engine for GameCube, PS2, and Xbox. They also improved the enemy AI. I could tell. The Nazis don't just stand there and shoot back. They drop back, regroup, even try to flank you. In addition your comrades' AI improves over the course of the game as they become experienced.
You play as a member of America's most decorated and heroic fighting unit, The Big Red One. You'll have to work with your squad to accomplish a variety of land, sea, and air combat missions spanning North Africa, Italy, and Nazi-occupied Western Europe. The goal of the development team was to "create an epic war movie" and they did. And then they threw you right into the middle of it.
I played for a few minutes. It is every bit as fun as the first one. I could tell right away that the enemy AI is improved. It should be out soon. If you like WWII games go get it.
