According to Kotaku, the social network is centered around four pillars: Career, Connect, Compete and Improve.
The first lets you look ar your own stats and look at how you rank against other players. Connect lets you set up groups based on common interests, similar to the way Facebook groups operate. Compete — shockingly — gives players a chance to go head-to-head in scheduled challenges and events.
The Improve section acts as a glorified version of a strategy guide, giving players a handle on basic features of the game as well as tips to improve their gameplay.
