Activision is planning to announce a new Guitar Hero game next month, according to a purported invitation to a reveal event that the company is said to have sent out to media in Germany, reports Gamereactor UK.

Gamereactor UK has since taken down its story, but NeoGAF preserved the original text. The language of Activision's invitation, as reported by Gamereactor UK, suggests that the event focuses on a rhythm game featuring rock music: The event is set for April 1 in "Hamburg Rock City," and Activision asked journalists to "rock the shack with us!"

A previous report indicated that Activision was building a new Guitar Hero game on PlayStation 4 and Xbox One, and would announce the project at E3 2015. The last entry in the franchise was Neversoft's Guitar Hero: Warriors of Rock, which launched in September 2010; Neversoft was folded into Infinity Ward in May 2014. Activision's main competition, Harmonix, announced earlier this month that it is working on Rock Band 4 and plans to release the game this year on PS4 and Xbox One.
