Digital Illusions' free-to-play third person multiplayer shooter Battlefield Heroes is doing something this weekend it has never done before. Starting on Friday at 11 am Eastern time the game will let players get double the normal amount of experience points while playing the game. That's something that Activision has done occasionally with the Call of Duty games.

The double XP feature is not automatic. You will have enter the following code into the game's redeem web page to get the extra experience points boost: 5RH4-G9WR-MVV2-Q4E7. The double XP time period will end at 5:59 pm Eastern time on Sunday.
