In Mortal Kombat (aka Mortal Kombat 9, 2011 version) for the PS3 and Xbox 360, you can fight Classic Noob Saibot during arcade mode to earn the hidden Brotherhood of Shadow achievement/trophy.
Wait for Noob to appear in the background of The Temple stage, and then win that battle without blocking at all and you’ll fight Classic Noob Saibot after your opponent is defeated.
Check out my other guide if you’re looking for the other Hidden Kombatants for achievements or trophies.
