The first batch of announced classes: Hunter, Warlock, and Titan.
Destiny is an online-only first-person shooter from Bungie, the original developers of the Halo franchise. It will be published by Activision and marks Bungie's first foray into development for Sony consoles. It has currently been confirmed for release on the Xbox 360 and PlayStation 3, and Activision's financial statements have indicated that the publisher is not expecting to see Destiny on shelves during the current (2013) fiscal year, setting the stage for a 2014 release, at the earliest.
Destiny is said to be Bungie's focus for the next 10 years, with the developer working to expand its universe beyond this first game. How those expansions will take shape and be sold remains to be seen, but the team has gone on-record and stated that Destiny will not require a monthly fee to play.
Destiny is set in our solar system, and players will form groups and traverse the galaxy in player-owned ships to conduct first-person shooter missions on planets like Mars and Venus. Humankind has been beaten back into one long city that sits beneath the Traveler, a large, mysterious sphere that helped defend the human race--or what's left of it--from various alien threats. Players will take on multiple enemy races in Destiny, including time-travelling robots, hulking rhino men, and more.
Unlike Bungie's past work, the story in Destiny is built around custom characters. The game has a class-based system, and three classes--Hunter, Titan, and Warlock--have been revealed as of this writing. In addition to firing rifles, pistols, rocket launchers, and sniper rifles, players will also have access to magic-like abilities, granted by the Traveler.
As an online-only game, Destiny will feature separate, third-person social spaces where players can collect, group up, and prepare for the missions ahead. Some mission zones will also be public spaces, allowing for players to encounter each other while out in the field and group up on-the-fly. Bungie has stated that the goal is to not show lobbies, matchmaking, or connection screens, instead delivering a more seamless experience. Player-versus-player combat will not be a factor out in the general world, but the game will feature some sort of competitive multiplayer component. Player counts for public spaces are not known at this time and will likely vary depending on the platform and network connection of the player.
