Mortal Kombat 9

Mortal Kombat 9 is a video game developed by NetherRealm Studios and published by Warner Bros. Interactive Entertainment.

The game itself has an Easter egg that follows the pattern of Mortal Kombat games, being a fighting game with brutal fatalities with a touch of black humor. In this entry however, there is a hidden screamer in Kripta.

The Krypt returns in Mortal Kombat 9 with a completely new look. Unlike in earlier games, this Krypt is now broken up into four sections: the Deadlands, Bloodmarsh, Hollow of Infestation, and Meadow of Despair, as well as the Nekropolis, which is where unlocked art, music, and costumes can be viewed; however, there is also a Kripta monster guarding the place, where if he finds you, he appears in front of the player with a loud scream. Afterwards, the exploration of Kripta proceeds normally.

Trivia

 * The Kripta Monster does not have an exact spot to meet, since he appears randomly on the map.
 * Sometimes small footsteps can be heard when the player stands stopped for a while, before the monster appears with a loud scream.
 * They say that this monster is one of Shang Tsung's unsuccessful Milenna clones.
