Marvel vs Capcom 2

I made a tutorial on how to do this one as well as 3 others...
Skip to around the 3min mark to see the part of the video that shows this achievement.

You can do this with ANY team of characters.
Simply fill up your combo meter to level 3 or more.
Then do a single Hyper Combo. Execute it by pressing: QCF (quarter circle foward: down, down-foward, foward) + X and Y. QUICKLY do the move again after your first hyper combo then QUICKLY do it a third time after the second hyper combo. They basically cancel each other out but you will see all three character do their hyper combos consecutively.

Edit: Make sure your 3 characters all have a hyper combos with punch buttons to work that way. Because not every fighter has one. Check your move list to be sure.

It must be done on multiplayer, online or local.

In this video Phe0nixAssass1n shows you how to unlock the "Shun Goku Satsu" achievement

Achievement Details:
Shun Goku Satsu (10 points)
Perform a 3 part hyper combo. (Multiplayer)

NOTE:
First set the timer in game settings to "Infinite", next you need to goto Local Multiplayer and choose 3 Cable's as the team you want to obtain the achievement.
The other team you pick 3 Amingo's.

Next get the Cable Team's "Level Bar" up to 4 by kicking and punching the air, when you obtain level 4 you press the following combo:
"Down on joystick then turn it to the Right Position and press X+Y" do that 3 times in a row like in the video and you will have the achievement pop up.

The Reason the accounts are "Player 1" and "Player 2" is because Phe0nixAssass1n already has obtained the achievement on his account so if he did the achievement again it would not appear so he made a basic profile up to show you that it pops up
