Not sure if this is iOS or not. Don't remember how UE works so i'm probably wrong, but i saw a cursor and chat box (as in typing) during it.... I could very well be mistaken though. If it is, another UE masterpiece! Sidenote: did anyone else notice the facebook sound ~ 0:20 in?
This wasn't even made in UDK Mobile. That's the interface for the normal UDK, and there are absolutely no original assets in the game. Also the text at the end says "lol trololol u mad? u jelly?" So I'm guessing this was just spam.
