Microsoft's much-awaited game Halo 4 is expected to officially launch on Nov. 6, but the game has been leaked and has made its way to many gamers.

On Oct. 12, many Halo fans found images of fully-printed game discs which started to appear on the Internet, and a number of YouTube videos showed gamers playing through the game's campaign mode. Many videos of the leaked gameplay have been removed from YouTube; however, the videos may have spoiled the anticipation of Halo fans who have been waiting for the official launch.

"I've worked for over 3 years making Halo 4. Please avoid spoilers and leaks from thieves for 3 more weeks until the game is out," commented John Holmes, Halo 4 Creative Director, on his Twitter page.

The two-disc game of Halo 4, which is exclusive for XBOB 360 console, was available as a 16GB download on torrent sites reports Cinemablend.com.

"Halo 4 launches in less than 25 days. The good news is that you are that much closer to having the game in your hands. The bad news is that as discs are being made and distributed, you may start to see leaks. The internet is an awesome place... until it's no longer an awesome place," said Microsoft on Halo Waypoint, Halo's official blog.

Microsoft further added "We are working closely with our security teams and law enforcement to address the situation. Piracy is illegal and we are taking vigorous action against it. We have poured our blood, sweat, and tears into Halo 4, and we want you to have the best possible experience with our game, come November 6. If you're interested in staying spoiler-free, we encourage you to exercise caution when visiting various websites, social networking services, and forums."

The leaks may have got the game in the hands of many gamers who have now played the game before the official release. Time will tell if Halo fans are still anticipating for the game to be launched officially and will lay their hands on the legit copies of the game.
