Instead of reading this you could be playing El Shaddai: Ascension of the Metatron. Ignition just put a demo up on Xbox Live and the PlayStation Store. All you need is a PlayStation Network account registered in Japan to download the file.
While a demo is up on Xbox Live, it is only available for gold members at the moment. Starting on April 20, anyone can get the El Shaddai demo.
El Shaddai: Ascension of the Metatron launches in Japan on April 28. Ignition will release the game in North America this summer with English and Japanese voice acting.
