From today until two weeks from now, God of War HD will be free to download and keep until your subscription runs out.
Chris Howe PS Store and Plus Content Manager said:
“We wanted to give this classic PS2 title away to celebrate the upcoming launch of God of War: Ascension, its immediate prequel. Ascension is a riveting, visceral experience that tells the dark past of our hero Kratos. The story will enthral you with epic, brutal and gloriously over-the-top action, retaining the signature gameplay of this storied franchise in a fully-fledged single-player campaign.”
“But that’s not all. For the first time, you can now take the larger-than-life God of War combat online with our new solo and team-based multiplayer experience.”
