If finally getting Sleeping Dogs wasn’t enough for you, Sony seems to have accidentally made God of War 1 and 2 free with PlayStation Plus. Currently it’s only affecting the two stand alone games, so don’t look at the Collection and get disappointed.
While we’re currently working under the assumption this is an accident, it might be possible this is an upcoming free Plus game or perhaps a replacement for one of the year long titles (as June is said to have new ones).
