Rockstar has continued to consistently roll out new content for Grand Theft Auto V’s online mode, GTA Online, since launch. It’s set to get one of its biggest pieces of content to date with the launch of a new online heist that arrives this week,  Tuesday 12th December on PS4, Xbox One, and PC.

Doomsday Heist is the first new co-operative multiplayer heist mission to be added to GTA Online in over two years, bringing the total up to six. It’s arrival is a bit of a surprise given that Rockstar had previously appeared to downplay the likelihood of new heist content.

The Doomsday Heist is described as a “massive new adventure” by Rockstar. Players will team up with an “unlikely alliance” between some of the game’s characters to save San Andreas from what appears to be the threat of nuclear annihilation. Here’s the plot description shared by Rockstar:

“A billionaire tech mogul, an idealistic intelligence agent, a socially awkward conspiracy theorist, and a neurotic supercomputer have been forced into an unlikely alliance to save San Andreas from total annihilation. As apocalyptic threats mount from enemies unknown, you and your criminal crew are enlisted to untangle mysteries and eradicate threats spanning from the bustling streets of downtown Los Santos to the ocean floor and all the way to the inner depths of Mount Chiliad in an epic new online adventure.”
