The King of Fighters XIII

I know this is really late, but PlanesWalker, make sure you hyper-hop after the first special, wait until your character basically touches the opponent (later than you think it should be), and the ex air fist will cause the opponent to actually go upwards, allowing you to land and get the neo max out. Make sure you're also buffering the neo max so that you can land and hit LP+HP as soon as you get the chance.

Maxima is clearly the easiest of the cast from what I can tell. Thumbs up from me. Billy Kane and Vice, while also easy, are still nowhere as lenient as Maxima's trials.

Trial #9 requires just the right timing on your jump and the juggle. Pay attention to the video or in game demo option. Notice Maxima does not jump until after Takuma bounces off the wall. After Takuma wall bounces, simply press Up, Toward for a small hop, input the EX attack so that you land before Takuma and immediately input the final move as you hit the ground (buffer the inputs while in the air then press LK + HK upon landing).

Also if you're struggling with the Max Cancel on Trial #10, make sure you are still in Hyper Mode ( + ). If the combo drops, simply hit the button to reset position and get full meter back. It's easy to forget you need to be in Hyper Mode to do the full combo and if you keep attempting long after your meter has drained you can't do the combo (though it fills back up over time). Simply resetting each time you mess up is faster.

For the Max cancel, try to input the super once the previous move connects. You can buffer out the super by mashing out Down, Toward repeatedly and the moment the previous move lands, press . Timing is everything.
