The demo for Enslaved: Odyssey to the West is scheduled to arrive on the PlayStation Network in North America on September 21. According to the announcement press release, an Xbox 360 demo is "coming soon."With developer Ninja Theory now taking over for an established franchise, we presume hardcore gamers will carefully examine the team's upcoming action title. So long as it takes more than three hours to complete, it will already have a leg up on Ninja Theory's previous offering. Yesterday, a demo for Enslaved appeared on the PSN for gamers in most of Europe.
