Karma engine????Maybe a DEV can help

[jamikey]

Whats up guys just a question on the "Karma Engine" . I read a long time ago about how the creators of unreal saw the "Karma engine" in actionat E3 and wanted to use it in the unreal engine or some such stuff. well I just read a new article in PC gamer saying that Americas Army is going to be implementing the "karma physics model"into the game. What exactly is the Karma engine? Is it only used on Vehicles? so does the Karma engine and unreal engine become one now?did the army have to pay sony to license this technology? just very interested about the game sorry for the Noob questions.
