Well basicly....

Story: Both Clans are attacked by a extremely large group of grey sticks called "The Greys". They all are expert fighters and have the power to increase their strength. Both clans engage "The Greys". At first both clans were easily beating these guys, but as more and more showed up, they became worn out. In the heat of the battle SSB tells Deus that he will go and look for help. Deus tells him to hurry back. SSB finds out that Sub-Zero is being attacked and starts helping them. Soon enough, all members of Sub-Zero escape with SSB to help Phoenix out. With 12 powerful RHGs, they are able to fend them off and escape to Phoenix's Underground Hideout. There the Leaders of the clans come to an agreement to team up and organize a well-thought out battle strategy to find out what's going on.
