Ninja Gaiden 3's difficulty-boosting update has landed, as has a demo for people who may still be on the fence after reading our less than glowing review. The "Ultimate Ninja" difficulty upgrade is free until May 24, although its related Ninja Trials and customization items will cost you - specifically, $9.99/800 MS Points for the whole kit and kaboodle.

Clan Battle multiplayer has also been updated with "an all-new shadow rule" and a higher level cap, changes ushered in via system update on the PS3 and through the downloadable "Ninja Pack 1 Lite" on the 360. Finally, the aforementioned single-player demo is available on both systems and features "all three weapons in a sample of the opening stage."
