This is one of the question I want interviewers to ask but...it never happens. So back then during the mk1-mk3 era lightning fingers were needed to perform fatalities, but in mk9 they could be tap.....tap......tap...tap...tap and still work.
So if anyone here who had a chance to demo the game would be so kindly to let me know on the time we have before the drop or if it is easy or hard to perform.

Plus I dont want to repeat this process:
1. Set number of Rounds to 1 if possible
2.Pick Characters in versus mode
3.Set handicap if possible
4.Bring down player 2 asap
5.perform fatality (failure goes back to step 2 or use rematch if avaliable)
6.Pick same character and try to perfrom all their fatalities (if rematch option available use it)
7.Repeat for the next 20+ characters

So if anyone can go throught this nostalgic frustration, i say kudos to you.
But for me I would really like the trainer to be in mkx.

Plus I only have 1 controller and a copy of destiny collecting dust
