Ninja Gaiden Sigma 2

The chapter challenge trophies do not stack, meaning you will have to finish all 17 chapters of the game on each difficulty for their respective trophies (68 chapters in total).

This trophy is technically harder than Clear the PATH OF THE MASTER NINJA as you need to clear Master Ninja in order to even unlock the Master Ninja Chapter Challenge mode, however, for the sheer requirements of each playthrough this is far easier than clearing it the first time. The reason is that all your weapons are available on every Chapter and they're all maxed out.

For this trophy you'll need to obtain a Master Ninja rank on every chapter challenge on Master Ninja difficulty. The Master Ninja rank requirements are not nearly as intimidating as you might think. In NGS 1 these were based on time, enemies killed, Ninpos saved, overall karma. In NGS 2 this is much easier as there's only one important factor that matters when trying to get a MN rank, i.e the number of enemies killed. What this means is that all you need to concentrate on is killing every single enemy you come by during the chapter. You can take even 40mins, even an hour to finish a chapter, lose all your Ninpo, die as many times as you want, just kill every enemy.

The only Chapter challenge where you might have trouble with this is Chapter 17, you will need to kill all fish in the blood river before entering the hall to Fiend Genshin and kill at least 5-6 Van Gelves (the big purple fiends) during the Dagra Dai boss fight. If you get lucky with the chest in the hall before entering the Dagra Dai boss fight though, you will spawn a group of ghost fish and killing those will 100% guarantee your MN rank for the chapter.

Good luck!
