After hours of playing here some tips on what to do:

1) Run, fire and dodge the whole time(O+L1+R1). Its harder for them to pick you up with fireballs and green beam.

2) Toggle left and right when they green beam you(L2)(they cant lock on when you do this).

Hope this helps.

Now the centaurs will get mad as red meter goes up. After they charge, screen goes blurry.

Press (O) and you get two circles coming from both sides.

When they meet in middle, shoot. Now they are dazed.

Grapple their shield(press square).

Once you have done this to both horsemen, now all they will do is green beam you.

To avoid the green beam, press L2 back and forth, they cant lock onto you as long as you do this.

As you shoot and crouch jump around to avoid them(O) wait for them to green beam then pick up your shield to shoot green beam back.

This will petrify them temporarily. Use your high caliber bullets or shotgun to take life away. Eventually, they will shatter when they have no more life.

Any one please help me out how to kill two horses in XBOX 360.
