This achievement is really simple to earn!
When you start Arcade mode, you'll be given a list of settings to change before starting the game.
-It can be on any difficulty, but if you wish to earn your achievement at a faster rate, set the difficulty onto Very Easy.
-Set the rounds to one and the time to 30 seconds or less.
Then start up the game, chose your character, and go through the next six or seven fights. Once you gone through the second to last character, which was Akira in my case, the screen shows a Vs screen between your character and Dural. Right then and there, your achievement should be unlocked!
Very fast to get! Have fun and good luck! If you cast a negative vote upon my solution, please submit a comment and explain why so that I can make the correct adjustment!
