Destiny is an online-only first-person shooter video game developed by Bungie and published by Activision. It was released on September 9, 2014, for the PlayStation 3, PlayStation 4, Xbox 360, and Xbox One consoles. Destiny marked Bungie's first new console franchise since the Halo series, and it is the first game in a ten-year agreement between Bungie and Activision. Set in a "mythic science fiction" world, the game features a multiplayer "shared-world" environment with elements of role-playing games. Activities in Destiny are divided among player versus environment (PvE) and player versus player (PvP) game types. In addition to normal story missions, PvE features three-player "strikes" and six-player raids. A free roam patrol mode is also available for each planet and features public events. PvP features deathmatch game modes, as well as objective-based modes. Players take on the role of a Guardian, defenders of Earth's last safe city, simply called The Last City, as they wield a power called Light to protect the City from different alien races. The Guardians are tasked with reviving a celestial being called the Traveler, while journeying to different planets to investigate and destroy the alien threats before humanity is completely wiped out.
