Ninja Gaiden 3
has a barrier to entry that not even Ryu Hayabusa can wall-jump over: busted Online Pass
from all over are coming in that the codes included with retail copies of the game don't work, effectively locking out the online multiplayer and generally being very
inconvenient for reviewers.
Game Informer's Dan Ryckert was able to purchase a new online pass
(presumably from the Xbox Live Marketplace, as PSN hasn't done its weekly store update yet), suggesting that the problem is with the actual printed codes, not the online service.
