Activision: Pretty much the creators of Call of Duty before Infinity Ward and Treyarch took over
Bungie: Makers of Halo but gave it over to 343 Industries after Halo Reach.

COD and Halo blending together to make a new game called Destiny. Activision is a worthy partner for Bungie as they've had their hands in both Modern Warfare and Black Ops and know how Infinity Ward and Treyarch work. Bungie is bringing sci-fi to the game and Activision is bringing the realism. If you like COD and/or the Halo series you're going to want to get this upcoming game. It was set to release this year, but Bungie and Activision give no promises. It is a huge game and may not make it out in 2013. But it should be no later than 2014. Its going to be the first ever first person shooter RPG. It's going to have an open world and online matchmaking. And there's also a problem if you don't know about the Treyarch/Infinity Ward/Activision split up. Just comment and I will get you any information. Stay posted because I will update any new information
