Do you guys remember when we saw the footage in the trailer of the chess kombat and we were like whos that green guy? well now we know that green guy is ghost(liu kang) so there must be some way to unlock him and if i do recall correctly not too long ago some kid posted that some guy had played as monster only the kid thought that it was an alternate of scorpion. this was even before the game came out. so there must be some way to unlock these people, we just have to look harder.
