With THQ in bankruptcy, the sequel continues development at 4A Games.

What you have is man entering this new Dark Age and the Metro is now the microcosm for society as we have it. There's this uneasy alliance between these different stations, some of them are fighting each other, some have formed alliances, some are trading with each other. You have these extreme mis-ideologies. The Nazis have risen, the communists of red line going hammer and tongues down there, so it's a pretty brutal state of affairs.
How have you improved the action in this sequel?
We’ve shown off a thrilling train ride in one of our demos. That's one of our more cinematic shooter experiences. But Metro really blends a huge range of gameplay styles from out-and-out action to stealth to exploration around the station cities. There’s a huge dose of survival horror as you're out on the surface in the ruins of Moscow and you're running out of air and you're running out of ammunition and you're desperately trying to find the next hidden range of stash to keep yourself going. There are lots of different gameplay styles in there.
Can you talk about some of the different types of enemies that come in both human and non-human form?
We have a lot of human enemies, but the post-apocalyptic world of Moscow is a pretty hostile place. There are mutated forms of all kinds of creatures roaming the land and the skies. We've brought back a lot of favorites and we've tweaked them and we've changed them for Metro Last Light. There's a whole new strain of mutants that you'll be coming up against.
