How to Activate: From the “Code of Honor” screen, press A, B, A, C, A, B, B on the Genesis controller

Speaking of Mortal Kombat. If you enter what essentially sounds like the band, Genesis’, 11th studio album at the Code of Honor screen (ABACABB), you’ll get sweet, glorious blood for the infamous, blast processing Sega Genesis. Sure, in all later console versions of MK, blood would just be in the game from the get-go.

But back in 1993 when the SNES and Genesis were competing, which version of MK did YOU buy? The version that had sweat fly out when you uppercut someone (SNES), or the one where you could enter a code and BLOOOOOD would fly out (Genesis) instead? Yeah, we chose the Genesis version, too.
