Running from enemy gun turrets, tanks and fighter planes is nothing new for players of "Battlefield," a franchise that fired its first shot in World War II but has since tackled Vietnam and modern combat. Its most recent tour of duty, "Battlefield: Bad Company," has sold 1.6 million units worldwide since June.
The next war "Battlefield" has waged, however, is a guerrilla assault on the free-to-play games business model. The game's publisher, Electronic Arts, is the first major U.S. videogame company to launch a free-to-play game, and it unveiled user statistics on its pilot game, "Battlefield Heroes," Thursday.
