Overwatch is a new FPS from Blizzard

Blizzard has revealed Overwatch, a new team-based first-person shooter for PC set in a technologically advanced Earth.

Players will get to pick from a cast of heroes in teams of six and battle across futuristic locations, such as hologram-lit streets of London or a high-tech Egyptian pyramid.

"In a time of global crisis, an international task force of soldiers, scientists, adventurers, and oddities known as Overwatch had come together to restore peace to a war-torn world," said Blizzard.

"After many years, the group’s influence waned, and it was eventually disbanded. Overwatch might be gone now... but the world still needs heroes."

"Overwatch is our take on a vibrant, near-future universe with amped-up characters and action-packed team-based gameplay," said Blizzard CEO Mike Morhaime.

"With every new Blizzard game, we look at our favourite aspects of a genre and put our own spin on things. Our goal with Overwatch is to create an awesome FPS experience that’s more accessible to a much wider audience while delivering the action and depth that shooter fans love."

A firm release date hasn't been released but beta testing is due to start sometime in 2015.
