Someone please explain combat codes to me....

[HadesWTF]

.....I use to get it when I was a kid but I don't remember them anymore and you have to have them to get Ermac, Mileena, and Classic Sub. I've found the codes online but its just a bunch of fucking numbers (like I'm suppose to know how the hell to enter that, its not a damn number pad). So if somebody could just help me out and explain what it is you do, I'd appreciate it very much.

... same as this system man. The numbers are like mk9. Klassik music? 101-101. No blood? 900-900.

and so on. I don't know any for UMK3 but, should be fine

This was written for the UMK3 that was on XBL, but you should get the point of how to unlock the hidden characters:
