Eminem has produced 12 songs based around previously unreleased verses from late rapper Tupac Shakur for the album "Loyal to the Game," Billboard.com has learned. Due Dec. 14 via Amaru/Interscope, the 16-track set will be the seventh album of Shakur's music released since he was shot and killed in 1996.

Although a full track list has not been finalized, the album will include guest appearances from such hip-hop superstars as 50 Cent, Jadakiss and Lloyd Banks, as well as Nate Dogg, Eminem protege Obie Trice, Outlawz, Sleepy Brown, Young Buck and Ronald Isley.

The four tracks Eminem did not produce were helmed by Raphael Saadiq, Scott Storch and Red Spyda. Shakur's mother Afeni served as executive producer in tandem with Eminem.

Eminem previously raided Tupac's vault for the 2003 soundtrack to "Tupac Resurrection," for which he produced three songs. The track "Runnin' (Dying To Live)," which featured a verse from fellow late rapper Notorious B.I.G., reached No. 5 on Billboard's Hot Rap Tracks chart.

As previously reported, Eminem's new studio album, "Encore," arrives Nov. 16 via Interscope.
