Basically, you access the menus by alternating between pressing the player 1 and player 2 block buttons a certain number of times, which can be kinda fiddly, and the secret “EJB” (Ed Boon’s initials) Menu pops up. For Mortal Kombat games, the unlocking requires the user to enter P1 (x5), P2 (x10), P1 (x2), P2 (x1), P1 (x2), P2 (x3), P1 (x4).
The Easter eggs largely act like debug menus, particularly in the first two games.
“Mortal Kombat” has always been known for surprises, but these secret menus prove just how deep the rabbit hole went. The player can also see all the character endings, which could normally only be accessed by completing the story mode.
In October last year, hidden features and secret menus were discovered inside Mortal Kombat game cabinets, more than 20 years after some of the games had come out.
MK3‘s Ed Boon menu is considerably more robust, and includes an option to immediately unlock hidden characters.
“It’s insane to think such a popular series of arcade cabinets could hold their secrets so long”.
The hidden menu in Mortal Kombat 3 gives you more options. It also allows you to watch every fatality-a demonstration normally reserved for players who have beaten the game on Master difficulty. Now, the secrets found in Mortal Kombat 1, 2, and 3 have been documented on video by YouTube user YourMKArcadeSource.
Newer versions of Mortal Kombat are still being released by Warner Bros. This is still an unexpected discovery, considering that the most recent of the three games is still more than 20 years old.
