Step 1: Materials
>An Xbox 360 controller (wired or wireless)
>a Torx size 8 star key (I got mine at http://www.evilcontrollers.com/ along with some improved analog sticks)
>2 momentary normally open switches (I used two of Radio Shack's part number 275-0644, they cost $2.69 a piece)
>A helping hands (they help a lot)
>A soldering iron
>Some thin jacketed wire (I got mine from a crappy old PS2 steering wheel)
>Also a utility knife for stripping the wire helps
>Finally, some snippers for cutting plastic
NOTE THAT YOU WILL HAVE TO REMOVE THE RUMBLE MOTORS TO FIT THE BUTTONS!!!
Step 2: Solder Up This Puppy
Also, the left analog stick's pins are buried underneath the left trigger assembly, so you'll have to cut it a bit. Just hot glue it back when you're done ad it'll be fine. Also, you should remove the trigger and it's spring before breaking it.
Step 3: Drill the Button Holes and Solder the Buttons
Step 4: Put It Back Together and Snipe on Halo With Ease
This mod makes sniping is Halo and COD easy.Aiming down sight with the sniper on Halo never worked well for me. Also, when running in COD, my thumb doesn't slide off the stick as much.
