Development of Halo 4 is complete with the game now in certification, franchise development director Frank O'Connor told an audience at this morning's Halo 4 press event taking place at the London Film Museum in Covent Garden.

"We had a big piece of news yesterday back in the office, which is that the game is literally finished at this point," said O'Connor. "They are handing it off through the various certification processes and that, and we're done.

"It's been three years of incredibly hard work by about 300 people."

With the game now in certification it's only a matter of time until the gold disc is sent to manufacturing to begin printing the millions of copies which will flood stores worldwide this holiday season.

Halo 4 will be released November 6 only on Xbox 360.
