Metro’s sequel was originally called Metro 2034, but perhaps this is the last light that name will see. The actual name of the Metro 2033 sequel was confirmed by THQ during an investor conference. It will be called Metro: Last Light and they have already registered two websites which use the title. Metro2033LastLight.com and MetroLastLight.com are currently unavailable at the time of this post, but it looks like we will see something appear soon enough (E3?).
Metro 2033 was previously released on the Xbox 360 and PC, but the PS3 version was canned. 4A games claimed that the game could run on the PS3. However, it is still unclear if the sequel will manage to make its way onto the platform.
