Guns N' Roses singer Axl Rose has slammed Activision and its Guitar Hero series for using his band's songs without permission.
The star wrote an open letter to fans suggesting he may be seeking legal action.
While he confirmed he did not object to former Guns guitarist Slash's involvement in Guitar Hero III, Rose claimed the songs 'Welcome To The Jungle' and 'Sweet Child O' Mine' had been used in an "unauthorized" state.
"Slash being in Guitar Hero is fine, but no when Activision in using 'Jungle' unauthorized," he wrote. "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."
