Ok so here's what we know from the E3 gameplay video:

1.The story takes place right after MK9 and goes as far as 25 years into the future.

2.We are going to see some old MK characters that have aged.

3.Each character will have 3 variations with different moves. Those will be exclusive to that version of each character.






4.2 new stages confirmed.

The cove. in which the waves will make corpses rise to the surface that can be used as interactibles.



Outworld Market Place. Interactibles will be available here as well. I think it is safe to say that every stage will have them.



5.New characters:
Cassie Cage

Daughter of Johnny Cage and Sonya Blade. She will have a combination of her parents' powers.

Kotal Kahn

We know nothing of him yet but his name suggests he might be related to Shao Kahn.

Ferra/Torr The little lady is Ferra and the big guy is Torr. She is considered to be the brain of the two. They will have different tag stances where Ferra is either going to be running on the ground or sitting on top of him. She will also be able to stab Torr, making him mad and causing him to inflict more damage. From the footage, the fatalities and Xrays are going to be performed only on Torr.

6.There is going to be a returning "Big bad guy" that apparently not many people will see coming.

That is all we have so far. You're welcome ;)
