Leaked documentation for Bungie's new "always-connected" first-person shooter says game allows players to create their own character and customize weapons, gear, and vehicles. Ahead of Bungie's expected announcement of Destiny on Sunday, artwork and information about the game has leaked out of GameStop. Joystiq has obtained a double-sided poster and other documentation, which not only reveals artwork for the game, but also gameplay elements. Destiny is Bungie's first project as part of a 10-year publishing deal with Call of Duty company Activision. Legal documents from May suggested that the game will be released for the Xbox 360 in 2013, with a 2014 release slated for the PlayStation 3. Stay tuned for more info as Bungi officially announce the game tomorrow.
