How to unlock the Antediluvian Slumber achievement in NINJA GAIDEN 3 - Definitive Guide
Story related… Cannot be missed. Towards the end of this chapter, you will find a Dinosaur boss. Attack this boss after it falls to the ground. Do not attack it while its up and running around. Make sure to take out his lower body first. It will turn a metallic silver. Then work your way up and only attack its head. If you're having trouble defeating this boss, see video below... You will get the trophy after you view the cutscene.
