Win with Batman using every special move and his Supermove
This can also be done Locally with a second controller or in a Private match with a friend. In the Character Select Menu, choose Batman. Any stage will do. When the match begins, open the Move List to view Batman's Special Moves. Land all 7 on your opponent and be mindful of the ones that require you or your opponent to be in the air. The Special Moves are:
Straight Grapple ()
Sky Grapple ( - opponent must be in the air)
Up Batarang ( - opponent must be in the air, unless facing large opponent like Lex Luthor)
Slide Kick ()
Scatter Bombs ( - must be performed in the air)
Cape Parry ( - blocking attack)
Supermove - The Dark Knight (+ - Meter Burn must be completely full)
Once all 7 moves and the Super Moves have been performed, finish the match by any means and when you win, the achievement will unlock.
Got this in story mode. And it looks like you dont actually need to land every attack. just perform it. not sure about most of them but I know that i did it without actually getting a hit with any of the air attacks. just input them, did land all the others including the super move and when i finished the fight, pop comes achievement.
This can easily be done in a Versus Local Multiplayer Match. Select Batman and reassign your controller to choose another fighter. Then reassign your controller to port 1 again and start the fight. When pausing the game you can check out the move list. Look for the section that says "Special Moves". You need to perform all 8 moves (including the super move) in one single match. You do not need to actually hit / damage your opponent with any of these attacks. Just performing them is enough.
this had me stumped for a while... the special move that is in the special moves list as (Air) you must be in the air... i know it sounds simple and makes me look stupid but i hope this helps someone who thinks the same way i do haha
