Originally due in March and then pushed to June, Chamillionare's sophomore album, "Ultimate Victory," is now penciled in for a Sept. 18 release via Universal.

In the meantime, the Houston rapper's "Mixtape Messiah 3" mixtape and DVD will be available for free download on his Web site beginning July 18.

"I've been hard at work, putting the final touches on 'Ultimate Victory' while my fans have remained patient and overwhelmingly supportive of me," Chamillionaire said in a statement. "Now that the new album is finally complete and the first official single is ready for release, I'm back on my mixtape grind."

As previously reported, "Ultimate Victory" boasts guest appearances from Busta Rhymes, Lil Wayne, UGK's Pimp C, Devin the Dude, Lloyd and Krayzie Bone. Three 6 Mafia, Rick Ross, the Runners, Play N Skillz, David Banner and J.R. Rotem are among the production contributors.

The latter produced the album's first official single, "Hip-Hop Police" featuring Slick Rick, which will be serviced to radio this month.
