For clean up, you need to do a single run through of a regular level, and also about two seconds of another level. Personally, I chose to focus on get all of the seals and what not, as opposed to trying to get the last two achievements, as Behind the Curtain and Days Long Past both come relatively naturally. During this time you will get the Days Long Past achievement for completing the level, and possibly a number of other achievements during this time such as Behind the Curtain, Back to Bed With You, and Cordyceps. The first thing you will need to do is a run through of the new DLC level in order to unlock most of the stuff you'll need for the other achievements. During this time you can complete all of your still unfinished achievements. Be creative with your kills and item usage to finish up most of the remaining achievements.Ī New Game + playthrough is required, which just involves loading up your game after beating it and selecting New Game +. As you finish up the point and collectable achievements, you will work your way toward " Marked". As your progress through the levels, try and aim for a high score in each level for " Descendant of Iga", and also be sure to look for the Scrolls for " Haiku", and pay attention to any bonus requirements for the 3 seals in every level needed for " Perfection". You will also unlock " Hismou's Heir" very early on, and you will want to focus on finishing a level without killing anyone or alerting anyone for " Mercy", " Masterful", and " Ghost". Your first playthrough will give you the primary story based achievements: " Awakened", " The Mercenary", " Escape", and " Fated". Your journey will set you against the people that attacked your Ninja Clan at the beginning of the game, and will involve considerable sneaking, and killing, to take out the man behind the assault. Mark of the Ninja puts you in the shoes of ninja with mystical power brought on by his mysterious tattoos. Glitchy achievements: " Masterful", " Ghost" (Not being detected, does not always work properly). Does difficulty affect achievements?: No Do cheat codes disable achievements?: No Cheats
Number of missable achievements: None (Level select). Minimum number of playthroughs needed: 2+ (If cleanup is necessary).
Approximate amount of time to 400 : 20-25 hours
