The announcement of the European version of the Ninja Gaiden Sigma 2limited edition, releasing on October 2, reveals bonuses mostly identical to the North American version -- by which we mean "that one book." The Ninja Gaiden Treasury , as it's called, includes the same strategy guide, comic, and art sections advertised with the American release, though Tecmo Koei Europe offers a bit more detail about it. The comic, for example, is a "prologue comic" designed by Team Ninja. The downloadable costume is also part of the LE.
Europe's version includes one thing the American release doesn't: a complete soundtrack. Other than that, it's identical -- right down to the exclusivity to a single retailer. The Sigma 2 limited edition will only be sold at HMV, for £39.99, though Tecmo's announcement says the RRP is £49.99.
