I've been thinking about what he told me weeks ago now that I have the game and I've been thinking about how many of the things he told me were right. There are more than 20 arenas. (Thats 1) Living Forest, Portal, ext. are playable. (Thats 2)
***SPOILER***
Shao Khan is mentioned in an ending (Thats 3 - and might I add he's added in a very HUGE way) If you want to see how Shao Kahn is mentioned, I'll put it below.
Thats all I can think of now because my mind is stuck on getting all the stuff I can manage with my greedy little hands from Konquest mode. LOL
***MAJOR SPOILER***
Havik's Ending~ The others had defeated the Dragon King, but left his broken body unattended on the floor of his throne room. Not long ago, a similar fate had befallen his former advisor, Shao Khan. Havik ripped the still-warm heart from the carcass and consumed it, thus absorbing Onaga's power to reanimate the dead. Had the Dragon King succeeded in his plans for total domination, the never-ending turmoil of life would have come to a stifling hault. Those who defeated him believed that the realms were at rest once more, but Havik vowed to restore the chaos that once ravaged Outworld. Shao Khan would rule again!
(Basically he used Onaga's power to reanimate the dead to bring Khan back to life! DUN DUN DUN!! LOL)
