I don't have the game either, but i know Mileena's second fatality, cause Konqrrr load them up on his site. Ok, i try it.
Spoiler!!!
Mileena throws her sais in the air, then he kicks the sais toward the opponent chest and the opponent screams in pain und fall on her/his knees.
From havik i just know, that he got Mileena's ( E3 ) leg beat and he eat the opponents arm.
From Jade i know that she rips the opponent in two halfes.
That's all i know. Maybe someone explain it better
