Eminem's newest single of his upcoming album is already out and fans can now hear a glimpse of what the rapper has been cooking up his sleeve.

A number of rumors have been swirling about Slim Shady's newest album - from talks of a Christian record to names of others artists he might be collaborating with. However, the rapper has not made any confirmation about the record, nor were there any signs of a new single, until now.

Earlier today, the Grammy Award-winning rapper dropped a clue to his fans, tweeting, "You won't wanna miss the @CallofDuty #GhostsMP event at 10:30am PDT" followed by a link to the streaming of the event. It turns out Eminem was referring to the new trailer of the upcoming video game Call of Duty: Ghosts which features his newest single "Survival."

Check out the trailer below to hear Eminnem's new beat:

The video started with clips from the battle video game, as Eminem's new song played in the background. Starting with the lyrics "This is survival of the fittest. This is do or die," sung by a female voice, Eminem continued the song with his trademark rhymes that prove why he is one of the biggest rappers today.

"Wasn't ready to be a millionaire, I was ill-prepared. I was prepared to be ill though, the skill was there," he rapped. Announcing his return, Eminem continued dishing rhymes:

"I'm f*****g back again with another anthem, why stop when it doesn't have to end? It ain't over till I say it's over. Enough when I say enough."

Eminem hasn't released a new album since Recovery in 2010. And while he had been collaborating with some artists, including Royce da 5'9 - which makes the other half of their hip hop duo Bad Meets Evil - fans haven't heard much from the Detroit native.

Notably, according to Radio.com News, Slim Shady also announced at the CoD press conference via taped video that he will be dropping his new album this Fall. However, neither title nor date was revealed.
