* DemonicSpiders: [[EliteMook The Stalkers]]. Not only they cannot be stealth killed as they have keen senses (they can identify the ninja within a certain radius), are extremely agile, persistent, cunning and their attacks can kill the ninja instantly. They also need to be stunned akin the Elites but are far more agile and acrobatic meaning that physical combat will most likely result in a NoSell. The final trial of the game has you temporarily locked in a large room with three of these!
* FridgeBrilliance: Use a Flare Bomb against enemies wearing Night Visions Goggles and you'll blind them.
* GoddamnedBats: The Dogs. They can smell the ninja even in the darkness and will start barking alerting the entire and room giving your position even if you try to move to another spot.
* GoodBadBugs: There's a way to glitch through the floor if you kick into a wall while jumping. Your character is also able to "fly" by using the parachute cloth, then entering and exiting Focus mode.
* HilariousInHindsight: Billie Lurks in ''The Knife of Dunwall'' DLC for ''{{VideoGame/Dishonored}}'' serves an eerily similar role as Ora in that she follows the PlayerCharacter around each mission [[MrExposition providing exposition]]. This would qualify for the myriad of other [[ShoutOut Shout Outs]] to stealth games that ''Mark of the Ninja'' employs...if not for the fact that the DLC came out about six months later.
* PlayerPunch: [[spoiler:Ora isn't real? And you want me to ''kill her''? Even if she really ''is'' just a hallucination, Ora has been the player's guiding voice throughout the whole game.]]
** And if you do [[spoiler:kill her, she dissipates into a flock of crows, and the scene changes to the Marked Ninja ''impaled on his own sword'', having committed seppuku.]]
** When you begin to make your decision, but before the [[spoiler:execution, your target will be shocked, then lower his or her head in a combination of sorrow, disappointment, shame and acceptance of his or her final fate. Hesitate and it's possible to change your mind, but the individual remains in the same position. It prevents any real clear 'right' decision, as both characters will accept and respect your final judgment.]]
