'Crysis 2' leaked one month before launch

Crysis 2 has appeared on file-sharing websites one month ahead of release.

Electronic Arts has said that the leaked PC build is "incomplete", encouraging users to wait until the full game is released next month.

"Crytek has been alerted that an early, incomplete, unfinished build of Crysis 2 has appeared on Torrent sites," read a statement.

"Crytek and EA are deeply disappointed by the news. We encourage fans to support the game and the development team by waiting and purchasing the final, polished game on March 22.

"Crysis 2 is still in development and promises to be the ultimate action blockbuster as the series' signature Nanosuit lets you be the weapon as you defend NYC from an alien invasion."

It added: "Piracy continues to damage the PC packaged goods market and the PC development community."

Crysis 2 will also be available on Xbox 360 and PlayStation 3.
