Undeterred by publisher THQ's shaky financial situation, the team at Ukrainian studio 4A Games are still hard work on the promising first person shooter Metro: Last Light, and an assortment of new screenshots have been dished out via the game's official Facebook page.

Beneath the ruins of post-apocalyptic Moscow, in the tunnels of the Metro, the remnants of mankind are besieged by deadly threats from outside – and within. Mutants stalk the catacombs beneath the desolate surface, and hunt amidst the poisoned skies above.

But rather than stand united, the station-cities of the Metro are locked in a struggle for the ultimate power, a doomsday device from the military vaults of D6. A civil war is stirring that could wipe humanity from the face of the earth forever. As Artyom, burdened by guilt but driven by hope, you hold the key to our survival – the last light in our darkest hour…

Metro: Last Light is due on PC, Xbox 360 and PlayStation 3 in March 2013.
