Unlock Ermac, Human Smoke, Mileena (ARC):
xblnss How to unlock the three hidden characters in Ultimate Mortal Kombat 3.

1. First of all, you're going to need two control pads.

2. Activate your second control pad and enter arcade mode, with any character, and on any difficulty setting.

3. Lose your first match and allow the timer to count all the way down.

4. After the timer hits zero, you'll be taken to a screen, where you will be able to enter codes. Each block in here corresponds with a button on the Xbox 360 control pad. You'll have 10 seconds to enter the code that you wish, so you'll have to be quick.

5. You have to hit each button on your control pads, in correspondence with the number at the side.

RB:?? 8
B:??? 3
X:??? 5
Control Pad 2
Y:??? 8
A:??? 1
RB:?? 8
B:??? 3
X:??? 5

The combination is the same for both control pads, it's kind of tricky to hit the same combination at the same time on two different pads though.

The combination to unlock Ermac is by far the trickiest of the three, as the number of times that you have to hit the buttons on each control pad is different.
