GamerDNA, the social platform for videogame identity and discovery, has announced the launch of new social tools. With the integration of Twitter and Tumblr into GamerDNA, gamers can now share PC and video gaming preferences and stories, gaming quiz results, and automatic summaries of games they've recently played. GamerDNA is also developing an API that will soon allow partner sites to take advantage of the company's social media integration across a network of millions of active gamers.
