Rare Replay

OK, here is everything you need to know to do this achievement.

Ultra Combos can only be performed when your opponent has a flashing red health bar, you have a flashing yellow meter and you are at least one hit into a combo. Their second health bar is red, and it will flash when at 15-20%. Your yellow meter will fill fastest when you're taunting or blocking. You need to perform one move before you initiate the ULTRA combo.

Here's a walkthrough with Sabrewulf since I learned how to play that character while trying another person's lousy advice.

Go to Arcade mode with 2 controllers. Choose Sabrewulf for player one. Once in arcade mode, you have 99 seconds to deplete your opponent's life to a flashing red bar. At this point, use the combo , + with Sabrewulf. This is his taunt, it will fill his meter until it's yellow and flashing.

Once the conditions are set, use the combo , + , this will initiate a combo that looks like a cartwheel. Quickly enter the Ultra Combo NOW, (HOLD) , + . If done correctly, it will show a cutscene and you will get an ULTRAAAAAA COOMBOOOOOOO!!

You can practice the sequence , + , (HOLD) , + while depleting your opponent's health bar. If entered correctly, Sabrewulf should do a cartwheel, then do a yelp/howl or something.


Congrats on your achievement.

CreepyB4by's solution isn't 100% correct. After reading the comments for it, I managed to get it just right every time.

To begin, start arcade, select Sabrewulf and then bring in a second player on a second controller.

To make life easier for future use a few notes.

1. You only need to have the health bar of your opponent to flashing red, you do NOT need to charge the power bar by taunting.

2. The actual move to get the combo is , +. While the cartwheel animation is going hold and charge then when the cartwheel ends +

I found it easiest to use and in the first round to take him down quickly then in the second round just use until his health starts to flash. Then perform the Ultra combo input and job done!

Go into options and change "Quick kick" to (I only suggest that because it is how I have it setup)

Go into Arcade with a second controller and select Sabrewolf, since his combo is far easier than anyone else's.

When the opponent's health is flashing red quickly hit:
+ , hold , hit , +

That will do the Ultra every time

The condition for an Ultra Combo is a red glimming life bar and a combo opener. I have chosen Jagos Double Kick as opener. The Input for this Kick: +FK
During this Kick you have to input his Ultra Combo.
Legend: FK = Fierce Kick, QK = Quick Kick
Jagos Ultra Combo has the following Input: + QK
So the full combination = +FK, + QK

Useful hint from Sambaweb: FK and QK are the buttons and in standard configuration

For the people like me who are terrible at fighting games, grab a second controller and head into Tournament/Arcade mode. Once in a match, block with the second character by backing up, and punch or kick while moving forward with the main character. Once the bar under your health is filled and flashing red, bring the second character down to his second (red) life bar. You can then continue with the combo that Dragoner28 has provided.

Note: it will not activate until the second characters health is around 1/4 left, leaving you with limited opportunities before finishing the round. Rinse and repeat.

This will also count towards the "Expiration Date" achievement as it will count as "No Mercy Finisher".

All solutions are very good but if like me, you got only 1 controller, you can do it easy in tournament mode. Opponant won't move. Also got the 5 Fatality achievements while doing this.
