Metallica drummer Lars Ulrich has revealed he can't keep up with his children when they play the band's new video game Guitar Hero: Metallica.

Ulrich said he found it difficult to adjust to playing the metal group's tracks, despite having the patterns "inbred" in his mind.

"I look like a complete fuckin' klutz because I can drum them in real life, but obviously there are slight modifications when it's transcribed for the game,” he told Blender.

"I have it inbred in me how to play these songs, but then I have to sit and look at little dots on a screen and try to figure out how to play it the way it's transcribed.

"Meanwhile, my 10-year-old and my seven-year-old are shredding on the guitars.

"It's kind of a mindfuck, sitting there, with my 45 years of semi-glory, and getting toasted by my kids."

As previously reported, Guitar Hero: Metallica will include 28 of the band's tracks, including 'Seek And Destroy', 'Nothing Else Matters' and 'Enter Sandman'.

Songs by others artists, including the Foo Fighters and Judas Priest, will also feature on the game.

Guitar Hero: Metallica will be available on Xbox 360 and Playstation 3 later this month.
