It's not uncommon for popular games to be stuffed with secrets, resulting in whispers of hidden unlockable content. While some of these turn out to be legit, a lot of the time these secrets turn out to be nothing more than urban legends.
The Mortal Kombat series is no stranger to urban legends. Myths about hidden characters, secret scenes, alternate Fatalities, and more have been a part of nearly every game in the series. Due to the popularity of these myths and urban legends, the developers of the Mortal Kombat games have often added them in future installments as a wink to the fans.
However, every once in a while, these secrets turn out to be the real deal. In the first Mortal Kombat game, players had the opportunity to battle the secret character Reptile, a palette-swapped version of Sub-Zero with a green uniform. Reptile has evolved over the years to become much more reptilian in nature. He was once a simple man in a green ninja outfit, but he has now become a scaled beast that spits acidic slime at his opponents.
As discovered by YouTuber JurassicRabbit, NetherRealm has included a nod to the first secret character in the franchise's history in the latest entry in the series, Mortal Kombat X. The video below shows how to access this homage:
In the Mortal Kombat 1 Living Tower, a secret fight against Reptile can be instigated in the sixth battle. In the first round, players need to achieve a Flawless Victory. In Mortal Kombat X, a Flawless Victory is when a round is completed without the winning fighter sustaining any damage.
Once this is accomplished, players need to end the fight in the second round with one of the franchise's trademark Fatalities. The combatants in the fight are irrelevant, so when trying to unlock this secret battle, feel free to use whichever fighter desired.
Upon completing these requirements, a message will pop up on the screen declaring that a secret fight is about to begin. This secret fight is against Reptile, but it's just the regular Reptile as he appears in Mortal Kombat X. While it's somewhat disappointing that NetherRealm didn't include Reptile's original appearance, it's still a cool reference for fans that remember the original secret encounter.
As extra incentive for unlocking and completing this secret fight, players will unlock an achievement/trophy called Keep it Secret. Keep it Secret is worth 25G on Xbox One, and is a Bronze Trophy on PlayStation 4.
The requirements of the achievement/trophy are a little vague. It simply states, "Find a secret fight in the Living Towers." This seems to suggest that there are other secret fights in the other Living Towers that are cycled through, whereas this secret battle with Reptile is likely exclusive to the Mortal Kombat 1 Living Tower. Whether or not the secret fights in the other Living Towers have different requirements or different opponents has yet to be determined.
Mortal Kombat X is currently available for PC, PS4, and Xbox One, plus a mobile version is available on iOS devices. The aforementioned mobile version is being ported to Android systems soon enough, whereas PS3 and Xbox 360 users can expect the console version of the game at some point later this year as well.
