I was just playing around with the options screen. Then I just thought what the hell I'll just hold some buttons and try to see if there would be any secrets. Well I didn't find any secrets, but I did see something strange.
When in the gameplay options screen I held R1+R2+L1+L2+square. Went to Blood Level and pressed down and then up again (so 1x down to the Kombat CPU and 1x up again and I'm on the Blood Level again, the whole time holding those buttons) Then I pressed right 10 x (On blood Level) and some numbers appeared on the right bottom side of my screen (0,098 to be exact). I have no clue what they do or why it's even there , but I thought maybe one of you guys know. Or at least confirm that you got the same numbers or none at all.. thnx
