EA Digital Illusions CE has quietly opened up the beta of Battlefield Heroes, their long-delayed, free-to-play shooter. After gradually scaling up the number of players in the closed beta, they've now made the game available to everyone and lifted the NDA. EA has not yet mentioned this in an official announcement, probably hoping to keep their servers from being overwhelmed. The game's website is now accepting signups. IGN ran a hands-on preview of Battlefield Heroes back in April.
