Mirror's Edge Catalyst, which according to my cats-as-historical-wartime-figures calendar was due for release late May. Well, not so anymore with the release date pushed back a few weeks until June 9 (June 7 for North America). In cat calendar terms that moves it from the tail-end (no pun intended) of kitten Julius Caeser, to the beginnings of Siamese Mao Zedong's rein of cuteness. Anyway, the reasons for the delay are due to the social play features of the game.

Stuff that will allow players to create their own time trails on the rooftops of Glass (which is the name given to the sprawling metropolis featured in the game), as well as the ability to leave hard to get to collectibles for friends to discover in their own versions of the city.

Here's a video covering some of the Social Play features coming to the game.
