PlayStation All-Stars: Battle Royale gets an infusion of fresh blood today with the addition of two more classic Sony mascots. First up is Kat, star of last June's Gravity Rush. Next is Emmett Graves, grizzled protagonist of Starhawk, who comes to us all the way from last May.

Okay, so maybe developer Superbot didn't dig too deep into the Sony library for these two, but the good news is that they're both completely free for the next two weeks. After that, they're $4.99 each.
