Valiant Hearts: The Great War

Most of the sequences are easy and you will get them in one go. The only one that gave me problems was the final line of the third sequence with Karl in the hospital. I would always screw up on it. So I wrote down the final line of the third sequence (Added the other 2 sequences). You can always pause at any time to make sure you know the next button presses. Take advantage of it.

1) AXXY----AXXY----AXXY----AXX--Y+B

2) AAAAAAA----XXXXXX----AAAAAA

3) AXX---YBB---AXX---YBB---AXX---YBB---AXX---YBB---AAAAAA---XXX--X+A

** Update **

Players recommend MUTING the crying child to help yourself better focus.

*** Update ***

One player recommends: You have to do the first QTE sequence (the one on the farm) perfectly. For the other two, especially the last one, if you mess up, let Karl die. It lets you go back to the checkpoint before you started the sequence.

For this in the mission Saint-Mihel of the chapter 4 you must save him all 3 times with no mistake. The 1st and the 2nd must be non-stop. The 3rd one if you fail just let him die and do it again from the checkpoint.
You can watch how to do it in the video.

This can only be done in Chapter 4 - "Saint Mihiel"

All three final attempts must be done perfectly, though they can be done out of sequence. It only says the third time because this is literally the third time she has saved his life.

ALL THREE FINAL SEQUENCES. DOES NOT HAVE TO BE ALL AT ONCE. You can do the third perfectly, then go back and do the first two, for example.

First off anyone playing on an HD 42" TV or higher like me probably isn't very easy because everything is faster and your eyes can't adjust to the screen. So what I suggest is to play on a smaller TV or Computer screen though you'll have to start over but just go through it play the level again and come back to this point you don't need to do the first two parts again perfectly, it saves it from before if you did it perfectly. This should make it slightly smaller you'll have to get use to the new screen for awhile.

If you don't have a smaller TV than just keep trying it on your normal TV. The snap feature worked best for this part but Xbox updated to no more snap.

Mute the sound. Make sure noise isn't affecting you. Close your door if you have to or go in a quite room. (Pause your game if needed to know whats next. Keep practicing the buttons for your memory to get use to the sequences.

If you miss or hit the button at the wrong time just mash buttons together that will kill/bleed out Karl so you don't have to redo the whole mission just the sequence again.

(Repeating sequence gradually gets faster and the final A's and X's slow the pace back down, kinda tricky there)

Just be patience don't stress about this achievement if you have to come back later for it or get a good nights rest. I know it's a pain I play on expert guitar on Guitar Hero and it's not very easy but doing it more and more makes you better to where you can do it. Don't give up!

DON'T FORGET COMPLETING GAME ACHIEVEMENT POPS AT THE END OF THE CREDITS WATCH THEM!

Congratz to people that beat this, is one tough cookie.

If you miss a button press in the final QTE you can intentionally fail by hammering buttons to kill Karl.

You'll start at the beginning of the QTE sequence so you don't need to restart the whole section.

THIS IS NOT MY SOLUTION - THIS IS FROM THE 360 GUIDE
ALL CREDITS TO PoundHound

Just one note from myself, the game will remember if you perfected one of the sequences.
For example: S1 Perfect - S2 Not - S3 Perfect -> no achievement
You have to come back for S2, once you perfect this one, the achievement will unlock.


PoundHound:

"First off, I believe that the event covers the whole of mission: Chapter 4 - Saint Mihiel. and you cannot make a single mistake."

"Run down the hill, enter the farm and pull the injured dude out of the rubble, and..."

QTE sequence 1:
- A ,A, A, X. A, A, A, X.
- AX, AX, AX, BY, BY, BY.
- A, B , Y, X, A, B.
"Part one done and dusted. Your patient is dumped in a car and you head off to the hospital."

QTE sequence 2:
- A, A, A, B, Y. A, A, A, B, Y. AX.
- B, AX, B, AX, B, AX.
- Y, Y, Y, Y, Y, Y (Y x 6), B, B, B, B, B, B (B x 6). AX.

"Phew! Sequence 2 done. You now have to find a med pack. It's not difficult and although the game tries to panic you with images of your patient getting nearer and nearer to death, I've never failed to make it back to his bedside before it's too late. However, should you need to do the mission multiple times, the quickest way I found was to head out of the room immediately to the right. Cross a short grassy area and you're back in the hospital. Take the first door and then head all the way back to the left. You'll see a downward set of stairs. Go down to the cellar and get the med pack from the wonky cupboard. Head back the same way. It should take you less that a minute."

QTE sequence 3:
- A, B, X, A.
- A, X, X, Y. A, X, X, Y. A, X, X, Y. A, X, X, YB.
- A, A, A, A, A, A (A x 6). X, X, X, X, X, X (X times 6). A, A, A, A, A, A (A x 6 again).
- A, X, X, Y, B, B. A, X, X, Y, B, B. A, X, X, Y, B, B. A, X, X, Y, B, B.
"The tempo changes after the first two here, so watch out for that."
- A, A, A, A, A, A (A x 6). X, X, X. AX.
"It's a sedate end, but don't take it easy. I messed up the last line a few times. Very annoying."

AGAIN THIS IS NOT MY SOLUTION - ALL CREDITS TO PoundHound

Important to know: you also need to save Karl perfectly the 1st (at the farmer) and 2nd (at the hospital) times (all during chap 4 Saint-Mihiel part). The good news is you don't need to do it all-in-one and when you correctly do a part it's good.

Valiant Hearts: The Great War (Xbox One) – Achievement – Healing Hero

Save Karl for the third time without making any mistakes.

This achievement is obtainable in Chapter 4 - Mission 5 - Saint Mihiel.

There are 3 QTE's that involving healing Karl. All 3 must be completed without any errors in order to unlock the achievement. If you perfect the first 2 sequences and mess up on the 3rd - You can let Karl die and it will reload from the 3rd sequence. As long as the sequences themselves are done perfectly, you can re-attempt each one as much as you'd like.

Once all 3 are completed without making any mistakes, the achievement should trigger.

Am writing this solution to complement other solutions posted here. All solutions posted here are good but what helped me was to figure out the timing to press the buttons in the sequence especially in the last one in the hospital with the crying baby.

Once you know what buttons to press, try to focus on the top of the strip, you will notice a small triangle. As soon as that triangle crosses the ECG sign (or whatever it is called), press the button. Do not press the buttons before that.

Also, sitting near the TV helps especially if yours is big because sitting from a distance does not help in focusing on timing.
