If you missed out on Metro 2033 and Metro: Last Light last generation, fret not. Metro Redux is bringing both games to next generations consoles (Xbox One and PS4) and PC (Linux and Steam versions planned later in 2014). Both games feature a graphical update, most notably 2033 which came out in 2010. It will use the same graphics engine that Last Light used since it was released in May 2013. There have also been artificial intelligence and general gameplay improvements that should make for smoother play.
The Metro series takes place in a post-apocalyptic Moscow, where citizens have been driven underground (into the Metro railway system) due to atomic weapons. In the outside world animals and humans have severely mutated due to the radiation and later become known as the Dark Ones. 20 years pass after the attacks when Artyom, the game/series protagonist and one of the fist born in the underground Metro, needs to protect his home against the Dark Ones.
The versions are available as individual game downloads for $24.99 (USD)/ or together as a physical copy for $49.99 (USD). EB Games Australia lists Metro Redux as $99.95 for the boxed versions, however IGN lists the individual downloads as “$24.99 / €19.99 / £15.99”. There is currently no release date, but its slated to arrive this summer.
