Starting life over at the DOATEC forums, there was this list of possible Ninja Gaiden II achievements featuring a total of 51 different goals, 19 of which are secret. Considering the origin of these (forum posting) we're gonna be safe and call these rumors. Especially when the achievements just seems so ... achievable. One would think that Team Ninja would want to tear its players a new one with such an opportunity as this, and yet if these are true they don't seem all that hard. They wouldn't be totally out of place though, considering that they reference Crystal Skulls (which have been seen in screens before), plus the easier ones are fewer points and the harder ones are vice versa. You decide readers, the full list can be found after the break.
