4A Games' global brand manager, Huw Beynon, was in London along with the firm's development team to discuss its upcoming action/survival-horror/shooter/RPG Metro 2033.
Based on Russian author Dmitry Glukhovsky's novel depicting a postapocalyptic Moscow, the game is expected to be released sometime during 2010 on PC and Xbox 360 and published by THQ.
According to Beynon, like in the book, the player is part of a few survivors who were underground on the Metro during a devastating event that wiped out most of mankind. Because of this, the survivors have stayed underground and have evolved to the surroundings.
There will be different sub-states and alliances along with different group dynamics in different sections, so some hostilities will come into play.
Anyway, stop reading this and watch the interview with IGN yourself past the break.
