DICE has posted over on the Battlelog blog information pertaining to the game's new dog tag system, which allows players to choose an initial design based on an in-game stat that will be tracked dynamically in the game.
Dog tags, which were first introduced in Battlefield 2142, are basically a bragging tool and this will be even more obvious in BF3, especially now that DICE has added "extra weight" to these "calling cards".
“Dog tags in Battlefield 3 go beyond just having your name on them,” explained Alan Kertz, senior multiplayer designer. “We have hundreds of dog tags that can be your personal calling card. Every time you kill an enemy, they see your tags. It’s your calling card – it’s your place to brag, and dynamic tags can show off how great you are with a knife, a jet, or even show off your personal play style.”
The only way to get a dog tag from from an enemy in the game is by performing one of the new knife takedowns which has you sneaking up from behind and performing a stealth kill.
DICE said that thanks to the ANT animation system, these special moves "add a dynamic visual flair," and encourage players to get in close for stealth kills.
"[It] makes bringing a knife to a gun fight the risky but rewarding experience it was always meant to be," said Kertz.
You can catch a glimpse of one of these stealth kills in the Paris multiplayer video released last week.
Battlefield 3 is out in October, and the beta starts in September.
