KISS has revealed the final piece of the cover for its 20th studio album, "Monster".

Using their recently launched "Monster Hunt" Facebook app, the rockers have been exposing portions of the image at various web sites around the Internet since last week.

The complete "Monster" cover can now be seen below.

"Monster" will be released on October 16 through Universal Music Enterprises. Described in a press release as a "12-track, straight-ahead rock 'n' roll album," the CD features collaborations among all four members — including co-founders Paul Stanley and Gene Simmons and longtime members guitarist Tommy Thayer and drummer Eric Singer — in an album that shows the band at the top of its game.

"Monster" is the group's first studio album since the band's 2009 smash success, "Sonic Boom", and was also produced by Paul Stanley with Greg Collins at Conway Studios in Hollywood, California, and The Nook in Studio City, California.

"Monster" represents KISS' nod to the music that first inspired them to pick up their guitars and flame-throwers and don makeup to entertain millions. The group goes back to their own beginnings with THE WHO-like "Freak", while Gene lives up to the title track's declaration on the raucous rock of "Back To The Stone Age" and the bludgeoning "The Devil is Me". Even guitarist Thayer takes a turn on his own with "Outta This World". a tribute to his KISS "spaceman" character, while drummer Singer provides the vocals (and the back story) for the arena anthem "All For The Love Of Rock & Roll".

"There are no symphony orchestras, boy choirs, keyboards, outside producers or songwriters on this album," promises Gene Simmons. "The best thing we did was to turn inwards to ourselves. Tommy and Eric have revitalized this band, with a work ethic and the talent to back it up. This is a real band effort. KISS has become a behemoth. We're going where no bands have gone before."
