How do i know which is the R3 and L3 button on the Ps2 Contrller

The L3 and R3 buttons are actually there, you just have to push the controller sticks down towards the controller itself. Put your thumb on either stick, and press instead of moving. That will get you back into the killing mode. Good luck with God of War. Cool game, lots of moves to learn, chests to find, and mythical monsters to slay...what could be better? ;)
Hope that clears up your problem.

L3 and R3 buttons are the analog stick press the the analog like a button and you should hear like a tick sound.

the left button on the left side is 1 lower key is 2 right key is 3 top key is 4 then it goes 5 and 6 for l1 and r1 7-8 for l2 and r2 9-10 for select and start 11-12 for the l3 - r3 This was found just testing my own controller so i can assume it is the same for you. Thanks, Midwest-tek

Hi a lot pf people get confused over this button but you know the two thumb controls that you can turn in all directions the round controls well you can press these down the left ball is L3 and the right ball is R3 so press the ball down and thats the button your looking for.

the L3 R3 are the joysticks! push down on the joysticks like buttons much like how you zoom in sum games its that,

I think someone is messing with you, for there are x,o, square, and triangle buttons, plus L1, L2, R1 and R2, and then select, start and then R3 and L3 but there is no,i say no y.there are y buttons only in xbox 360 if this helped you or you think i spent some time to answer your question rate helpful thanks

1. Hold R1+R2 then press Square, Triangle, Square, Triangle
