An epic space adventure set in giant open world setting, the hugely anticipated video game Destiny was released worldwide today. Available on Playstation and Xbox consoles, it's the latest effort from game studio Bungie, creators of the Microsoft's best-selling Halo series.

"It's a persistent, online, shared world where every Guardian that you come across is a gamer, and you can play in many different modes and whichever way suits you at that moment in time so to have that sort of experience where you pick up and play and go and decide what you want to do, where you want to go, go with your friends, go on your own, go with people that you'd never met before, I think it's just going to be fantastic."

As well as its enormous ambition, the game is noteworthy for its staggering cost. Activision have spent around $500m, a little over £300m, developing and promoting Destiny, making it the most expensive video game ever made.

"I guess it's kind of like shooting a rocket into space right? you need to spend a lot of energy on the fuel just to get it up in the air, but once you get it out in to orbit the sort of forces and gravity do its work, and its a lot easier ride, it's just getting it up there in the first place, that's where the 500 million's going."

But will it pay off? The signs are certainly hopeful. Fans in London queued up for hours to get their hands on the game at a midnight launch party, and there's a good chance that Destiny can follow in the footsteps of Halo, Call of Duty and Grand Theft Auto and become the next multi-billion dollar video game franchise.
