HOW TO DUEL:
- Press L2 or pull back and then forward on the right control stick to draw your gun. L2 is easier.
Drawing
second means you'll have more chance of winning - sounds counter-intuitive, but it's true. I'm led to believe this is because your accuracy is improved (to compensate for your late draw). Your best bet is to wait until the screen turns sepia and flashes 'Draw' or 'Let's Draw' or whatever the text is - and
then press L2.
- Paint the other dueler using the R1 button.
The important thing here is to wait until the crosshairs turn small and white. They start out big and red and gradually close to a point - you'll do better if you hit R1 as close as possible to the point where they are at their smallest.
And that's it! When your dead eye meter runs out on the right, you'll start shooting.
A few other points.
Jamoking: R1 is the button you use to paint, not R2 (under the default settings).
To the flamers: there is
nothing in the manual about dueling. Go have a look yourself before you flame someone for not finding all that non-existent info on topic x.
