Earlier today Eric Koch, Senior Producer of God of War: Chains of Olympus, officially announced on Sony's PlayStation blog that the eagerly-anticipated PSP action title is now completed and going into mass production.

"The great news I have to share with everyone is that Kratos will be in your hands on the PSP March 4th. That's right people, we are now officially GOLD and the game will be hitting your retailer shortly," said Koch in a brief entry.

As a bonus post, marketing team member Asad Qizilbash unveiled the teaser ad for Chains of Olympus and revealed the plans for the game's ad campaign. SCEA will be working with the CG crew that worked on the visual effects for "300." After seeing what the team at Animal Logic did with one set of Spartans, one can only imagine what they'll do with this one.
