Without warning, like the shadowy figures known only through whispers in the night, Ninja Gaiden Sigma has made its presence known on the PlayStation Store. The demo will be available today in the US, one day prior to its Japanese release, alongside a demo for Virtua Tennis.
Also coming out today are trailers for Gauntlet II, The Wheelman, John Woo's Stranglehold and The Godfather. The full version of Ninja Gaiden Sigma is set for a June release (on disc).
**Update**
It is the 27th in Japan, which happens to be the 26 in the states, so by paper it is 1 day gap.
