GPLast Light builds roughly at the point where Metro 2033 has stopped. Or it builds up where the game has to stop. For Metro 2033 came with two possible endings. One of them was rather tragic, true to the 700-page novel of the same name by Dmitry Glukhovsky. The other gave us a conciliatory goodbye from the Moscow underground. Metro: Last Light takes the tragic end of a novel as a template.
