It doesn't say move action. It just says an action and attempts to move. That's the part I'm focusing on.

No, break away states an action and then attempts to move. Not a move action. So it could be any action, then the attempt to move.

In this case, the action is a free action close combat attack, and the attempt to move is the remaining hypo.

this is obvious, otherwise one would not have to break away to use Charge, Hypersonc Speed, etc.And once again, you're not beginning to move. You're continuing the movement that you already started, and you do not have to roll break away once your movement has begun.

But it doesn't say begin, it says attempts.

If a character occupying a square adjacent
to one or more opposing characters is
given an action and attempts to move, that
character must successfully break away
before it can move, as shown in Figure 8.

Once you're already moving, there is no more "before you can move."

But it isn't saying at the beginning of the movement. It is talking about the attempt to move. Flash stops moving to make the close combat attack. And starts moving again. I do not mean to frustrate. Just trying to iron it out.

Flash never stops moving.
The attack happens during the movement.

That is why if your movement is stopped before making the attack you can't make the attack (like a hypersonic speed character with the boot symbol entering hinder terrain).

He does NOT stop moving to make an attack. He is moving and attacking at the same time. He is attacking DURING his movement, not after. The movement completed after the attack is not attempted. It has already succeeded, it is merely being resolved.

This is distinct from Charge and Running Shot, where the movement is over and then the attack is made.

HYPERSONIC SPEED
Give this character a power action and move it up to
its speed value. It adds 2 to its d6 roll when breaking away and can use
.
During its move, this character may, as a free action, make one close combat or ranged
combat attack with its range value halved for the attack. This character must be in a
square where it could legally end its move in order to make the attack.

This is a copy and paste of the power and abilities card for Hypersonic Speed. A character that uses Hypersonic Speed never stops moving for the attack.

It would have to stop to Make an attack. For game effects like shape change. The free action happens during the movement. But that doesn't mean it doesn't stop moving.

Actually the RULES say that the character does not stop. It DOES NOT STOP to make the attack. The attack happens during the movement, I literally just posted the OFFICIAL POWER AND ABILITY description of HYPERSONIC SPEED and it says DURING THE MOVEMENT.

I will repeat, the character DOES NOT STOP MOVING FOR THE ATTACK.

Just cause you stopped moving your figure across the map does not mean that in GAME TERMS that the figure has stopped moving.

I know I'm frustrating. But I need an official ruling for this from somewhere that says movement does not stop. Because if it doesn't, I can target a character with shape change, shape change succeeds, I must pick another target for attack. But since I don't stop, I can move on to another legal target.

My logic is this. It says during your movement. That doesn't mean you do not stop. You have to pick a square to me an attack. You target from that square. So things like shape change can work. So you stop moving in that square, and take a free action. After that action resolves during the move, you continue to move. This all happens during your movement.

But for break away, you make a close combat attack and continue your movement. You have to give a free action during your movement no matter how you slice it. And break away says, once you are given an action and attempt to move, you must break away. It doesn't specify what type of action. And it Doesn't specify begin to move. You give a free action and are attempting to move with the rest of your movement. You are trying to continue the movement after the free action.

To me, that says you must break away.

No. You cannot continue to move during the attack in HSS. This is clarified in the Player's Guide.
