Metro 2033 didn’t receive the backing it deserved and was slightly rough as a result, THQ has admitted.

“Last time around on Metro 2033, THQ came to realise a little too late that it had this unpolished gem on its hands,” said THQ’s head of global communication Huw Beynon.

“For whatever reason, that meant that the first game didn’t quite get the production support from THQ that could have raised the polish and quality level a little bit.”

Despite this, the game went on to sell more than a million copies on PC, making it “a bonafide hit” according to Beynon, who added that his studio would not make the same mistake with its upcoming sequel, Metro: Last Light.

“This time around, they were aware of what the potential could be, so we’ve seen that extra support, both in terms of focus from them in assisting production – generously giving the studio a little more time to get the quality that we needed.”

“Given THQ’s [financial] situation, that was obviously a big decision, but I think one that’s going to pay off.”

Metro: Last Light comes to PC, PlayStation 3 and Xbox 360 in early 2013.
