Metro: Last Light is the follow up to Metro 2033. The delay is as a result of the IP migrating from THQ to Deep Silver.
A new Metro: Last Light release date has been revealed, with the games set to ship in May 2013.
Landing in the US on the 14th and across Europe on the 17th, the game was originally due to be released in March, but new publishers Deep Silver wanted to allow a little more time to add some final polish to the product.
'We won't leave that time unexploited and will work closely together with 4A Games to make the game even better. It will receive all the attention it deserves,'
said Deep Silver's parent company Koch Media's chief executive, Klemens Kundratitz.
Deep Silver bought the Metro IP during the initial auction of THQ's assets in January. It is a follow up to the post apocalyptic Metro 2033, also created by 4A Games and released in 2010. Deep Silver also revealed it does have further plans for the future of the series after Last Light is released.
'We would like to thank all of the Metro fans for their patience. And we can assure them that we have a lot more coming their way with the franchis,'
said Deep Silver international commercial director Menno van der Bil.
Metro: Last Light will be making its way to the Xbox 360, Playstation 3 and PC.
The Metro games are based on a series of novels by Dmitry Glukhovsky. Metro 2035, the follow up to Metro 2033 and Metro 2034, will be released outside of Russia later this year.
Some of THQs last remaining IPs including Homeworld, Darksiders and Red Faction are set to be auctioned off on April 1. Included in the auction are the rights to Double Fine's Costume Quest and Stacking, which the indie developer hopes to secure for itself.
Other THQ refugees that were auctioned off earlier this year included the South Park RPG, Stick of Truth, which has been bought up by Ubisoft, and Homefront which was acquired by Crytek. Deep Silver parent company Koch Media also picked up Saints Row developer Volition for $23m, outbidding Ubisoft's $5.4m offer.
