TellTale’s episodic The Walking Dead series ambled to the top of the PlayStation Network sales charts for the month of May. The downloadable adventure was joined by thatgamecompany’s Journey in second and PixelJunk Shooter in third. It was a strong anniversary month for the Q-Games developed series, with no less than four of the franchise’s most popular titles making the cut.

Elsewhere, Escape Plan’s reign at the top of the PlayStation Vita chart was ended by Mortal Kombat. The NetherRealm developed port overcame fellow new release Table Top Tanks to claim the top-spot, while spin-off Resistance: Burning Skies settled for a place in fifth.

It was all change on the PSone Classics chart too, with the arrival of Legend of Dragoon temporarily displacing faithful favourite Final Fantasy VII from the number one position. Max Payne dominated the PS2 Classics chart, while God of War: Ghost of Sparta returned to the summit of the PSP list.
