Really, you shouldn’t be watching this. You SHOULD be playing the game; Mark of the Ninja is an amazing stealth action title on XBLA that was well worth the $15 I paid for it. However, should you not have a 360 or hate stealth games, then here’s your set up:
You play as a ninja who’s clan is attacked by a group of mercenaries. Many ninja are slain and to take revenge, your clan’s master Asai grants you with a “mark”, a tattoo where the ink gives you supernatural abilities of heightened speed and stealth. However, the tattoo makes the wearer slowly go insane, and by the end of the game, you start to become unhinged as you’re faced with the decision to kill your master for having brought shame to the clan or to kill the partner who you comes along with you the whole of the game.
