This week also sees the release of Capcom's classic 2D fighting game JoJo's Bizarre Adventure HD, as well as action role-playing game Legasista.
Sleeping Dogs owners will be able to download the 'Top Dog Gold Pack', 'The Red Envelope Pack' and 'The High Roller Pack', while curious parties have access to a demo.
The update is topped off with new Saints Row: The Third's ' Planet Saints Pack' DLC, costing £4.49.
