The next game from Halo creator, Bungie, has been leaked onto the internet. The project had been one of publisher Activision’s most closely guarded secrets.

The game is going to be called “Destiny” and it is planned to have a universe as deep and rich as the Star Wars universe.

Activision has previously told investors that the game would be “genre-defining” and prove to be one of its two “largest growth opportunities” over coming years, alongside the Call of Duty series.

Following the leak, Bungie reproduced one of the images on its own site and confirmed the leak’s authenticity.

The game will be set 700 years in the future, and feature battles with aliens to protect the “last city on Earth” after the collapse of mankind’s efforts to colonise the Solar System.

Microsoft has said it has plans for at least another two Halo games. Its most recent sequel, Halo 4, was created by its own subsidiary 343 Industries. The series as a whole has generated more than £2.1bn in revenues to date.

Pier Harding-Rolls, head of games research at IHS Screen Digest said “You can never have sure bets and the risks involved with creating new IP [intellectual property] are always relatively high, but to have a studio like Bungie involved reduces the risk considerably for Activision due to its incredible track record

“I’m sure we’ll see a lot more of it at E3 [games conference] in June where games like this can be shown in a satisfying way.”
