GUNS N' ROSES frontman Axl Rose has slammed the makers of popular video game Guitar Hero for allegedly using the band's songs without permission.
The singer has written an open letter criticising manufacturer Activision, claiming his hits Welcome To The Jungle and Sweet Child O' Mine are used in the game in an "unauthorised state".
Former Guns N' Roses guitarist Slash is heavily involved in promoting the Guitar Hero game, and Rose admits that although the guitarist does have the right to perform the songs they created together, Activision should not play on Slash's former links to the band to help sell the game.
The letter reads, "Him (Slash) being (in) Guitar Hero's fine but not when Activison is using ' Jungle' unauthorised.
"I wasn't broadsided. I read about it as it moved along but Activision continually denied it right up to the release. That's some low life chicanery on all their parts.
"Yes, Slash was in Guns and on ' Jungle' and he has rights to perform it, but not to be represented in this context in association with Guns. And since they weren't granted the license it'll take some sorting."
There are currently five separate teams working on 'Game of Thrones' projects at HBO.
She's a big fan of the band and this week she got to perform with them.
