In effort to pique interest in a game that has been on ice since 2011, new developments will allow die-hard “Guitar Hero” fans to rock on a level close some of their guitar idols.

Activision CEO Eric Hirshberg first unveiled the official “Guitar Hero Live’’ trailer before an industry-heavy crowd Tuesday at New York’s Best Buy theater and then handed over the mic to Jamie Jackson of FreeStyleGames, the designers behind “DJ Hero,’’ who are updating the franchise for the 2015 market.

Updates included a redesign of the guitar-shaped controller and Jackson noting how the how the necessity of the ring and pinky fingers on the old fret board design often made it impossible for users to make it past medium difficulty.

He then invited bassist Pete Wentz of Fall Out Boy to the stage, to play along to the band’s “Save Rock and Roll’’ hit “My Songs Know What You Did in the Dark.”

Wentz played his band’s song on Advanced, messing up a few times to the chagrin of the game’s virtual audience who react dramatically to all of the user’s successes and failures, Rolling Stone reported.

Hirshberg returned to the stage to present another key component of the new game: “Guitar Hero TV.”

In this mode, music videos spanning all genres are culled from the web for users to play either on their own or against another user. My Chemical Romance’s Gerard Way competed against Jackson on MCR’s “Na Na Na.”

With its constantly updating catalog of music videos, the mode will allow users to always have new music to choose from as music videos across all genres are released.

The last “Guitar Hero” entry, Warriors of Rock, was released in 2010, and a steady decline in sales and interest forced Activision to officially put the franchise on hiatus in 2011.

”Guitar Hero Live” will be available this fall.
