Lin Kuei: The entire clan shows up to pelt you with snowballs until you freeze to death.

Edited the title cause it didn't need to be all in caps.

I have a feeling each faction will have at least 2 fatalities specifically for that faction. I don't know how it will work out though. It is an interesting addition I'll give it that.

We've seen the Special Forces one = Flamethrower Machine

I can just see the Black Dragon using some sort of "death laser"

Perhaps one of Raiden's lightning strikes for the White Lotus?

The Netherrealm, some type of demonic sorcery (perhaps drag them to Hell)

And the Lin Kuei would probably use ice of some sort.. I guess

I think a faction kill would be a cool oppertunity for a cameo from a character that didn't make the roster.

A good question would be if it is limited to the faction you choose only. Or maybe the flamethrower fatality was a stage fatality or sektor?

I like this idea

Why does it have to be something of Raiden's? He will get replaced once Liu is konfirmed, like Cassie got replaced by Sonya.

There is no Netherrealm Faction, it's Brotherhood of Shadow.
