    This can be done in arcade or campaign modes and can be done with one or two players. Be sure to select "play co-op". I did it by myself (no player 2) in co-op arcade mode with Black Widow & Magneto.

    When the match starts, initiate a super move with your first character, then raise your left arm to switch characters, quickly initiate two super moves with your second character, then raise your arm again to switch back to your first character and initiate another super move. If timed correctly, you should have completed a 4X Super Tag Combo & the achievement will pop.

    - Use a launcher super move before you switch characters.
    - In campaign or arcade mode, be sure to do this on the first fight because the difficulty increases with subsequent fights and your combos will be interrupted more frequently.
    - Check out the YouTube link if you are having difficulty; following the process in the video, I got this on the first try. I did not create this video. Credit goes to YouTube user ObeyorDIE.

    NOTE: If you do not yet have the "Power Duo" achievement, playing an arcade or campaign co-op game will also unlock that one.

    LitaOsirisJust to note that if you have issues getting this to unlock simply restart your Xbox. It will unlock on first try then.

    MathGuy42It's possible to do this with just one switch. I used Magneto and Hulk. Did Magneto's leftmost attack, switched, then did all 3 of Hulk's attacks from left to right.

    This does not require 2 people. When you start up Campaign, choose co-op. Play the first mission and do a triple combo with one character and quickly switch characters with your left hand and do one more super attack.

    Once you hit a 4x Combo this will automatically unlock.

    Apparently you can do this in Co-op Arcade Mode as well with two characters you feel comfortable with using/switching between to combo their Super Attacks.

    Thx to Munoz2024 and bozack for the helpful tips.
