Mortal Kombat Cheats (Genesis)

Arcade Mode

Wait for the screen that says “The word “code” has different definitions”, then press:

 A, B, A, C, A, B, then B 

If entered correctly, the letters will turn red and Scorpion will say “Get over here!”. This will unlock all Fatalities and blood effects.

Secret Boss (Reptile)

To unlock the battle with Reptile, start the game in one player mode. Fight until you get to the area known as “The Pit”, which is a bridge over some spikes. Follow the instructions below if you see a shadow cross the moon.*

-Win both rounds in The Pit with a flawless victory

-Do not use the block button during these rounds

-Finish the opponent off with a Fatality

If done correctly, your character will face Reptile at the bottom of The Pit.

*Note: This only works if a shadow crosses the moon over The Pit. Use the Super cheat code below and set Flag2 on the cheat menu to force the shadow to appear.

Super Cheat Mode

At the game start/options screen, enter the following button combination: 

Down, Up, Left, Left, A, Right, then Down 

This unlocks the cheat menu which gives players access to Mortal Kombat’s famous “Blood Code” and many other settings. Select the “Cheats Enabled” to change settings like the chop-chop mini-game, starting map, and even the order of opponents. Players can also toggle various Flags which have the following effects:

FLAG0 and FLAG1 – Starts players off with extremely low health

FLAG2 – Makes sure a shadow appears in front of the moon in The Pit, which makes it possible to battle Reptile

FLAG3 – Changes the moon shadow into Probe Software’s Fergus McGovern’s face

FLAG4 – Gives the player hints about Reptile before every battle

FLAG5 – Infinite continues

FLAG6 – The computer will perform Fatalities

FLAG7 – Background is permanently set to Palace Gates
