How do you beat the last boss in god of war chains of Olympus

The way I beat her is that I dodged her lunge at him then Attacked using the Zeus Fist by holding L + Square

After you get her life down enough she will grab you then you will go on the titan pressing some buttons and gaining life

When you get down she will throw stuff at you then tap L button to throw it right back at her [after the first time she will have more attacks on you, then you will have to do the same thing] When she is down hit her until she climbs back up

When she is on the ground regaining some of her strength go in the golden circle then Press L, Then It should say to Press Tap CIRCLE and that's it
