Noob Saibot's Dorfen is a secret arena that has appeared in MK3 and some versions of UMK3.

In this arena, you can only fight Noob Saibot, Sub-Zero's deceased older brother, and servant of the Brotherhood of Shadows, demonic zealots of the fallen Elder God Shinnok. On the other side of the Soul Chamber hole and across from Motaro's balcony, Noob Saibot has his own sanctuary where he hides within the shadows. Noob's Dorfen is merely The Balcony itself with the back wall and Centaurian statues removed. Additionally, Dorfen is an anagram for Forden, the last name of Dan Forden.
