How do you hold your controler?

Right hand on the mouse, left hand on WASD, left thumb on spacebar, little finger on shift.

I actually hold my controller like an xbox controller because the PS3 controller that I use was made from Gamestop and it resembles an Xbox controller more than a PS3 one.

i hold down my middle finger

yes, i have a PSN in my sig - i use a xbox360 to ps3 converter, and it is worth it!

I can leave my thumps to all time on the sticks. 6 extra buttons to map, which can be reached easy with the middle finger, or the index finger.

genius thing - u never want another controller.

p.s.: and as far as i know MS and Sony didn't made extra buttons under the controller with the new controller for xbox1 and ps4

Usually I have my index on L/R1, middle on L/R2, and thumbs manage the analog/d-pad/buttons in games. In DS I've found the claw method, where index finger manages the right side buttons and middle deals with the triggers, to be better. Being able to move the camera easier opens up more possibilities like smashing someone's face who was trying to be sneaky DS sure has taught me some things. I didn't know about the claw method til a youtuber mentioned they use it in their DS vids.

I use my thumbs for everything, analogs, X O △ □, Arrows, start and select. For R1/2 and L1/2, my right and left index fingers
