The winners of the 14th annual Interactive Achievement Awards were announced at a ceremony last night, after an extensive list of nominees was announced in late January by the Academy of Interactive Arts and Sciences (AIAS).

As has become the trend at award ceremonies for games released in 2010, Red Dead Redemption cleaned up and took no less than five awards in categories such as ‘Outstanding Achievement in Art Direction’ and ‘Outstanding Character Performance,’ while Heavy Rain, Mass Effect 2 and Limbo also received multiple awards.
