Imagine a world where global warming has contributed to a massive catastrophe. On top of all of the environmental issues like drought and famine, the icecaps and glaciers have all melted, causing sea levels to rise dramatically. With a large amount of the world's population killed, the last refuge of humanity lies in an artificial floating city as sea known as the Ark. This isn't an emergency scenario trying to force countries into ratifying the Kyoto Protocol – this is the backdrop for the latest shooter from Splash Damage and Bethesda. At E3, Splash Damage showed off some of the gameplay from a pre-alpha build for this upcoming shooter, which will land on the PC, PS3 and 360 in Spring 2010.
