How to use your PS3 controller in Left 4 Dead PC.
This tutorial is for people who want to use a Playstation 3 controller to play Left 4 Dead on the PC, either because said people don't have an X360 or just prefer the PS3 controller.1) First off, you will need to install the PS3 drivers for your computer. You can get it here (XP) or here (Vista). Extract the files anywhere and run "libusb-win32-filter-bin-0.1.10.1.exe". This will install the drivers you need. 2) Now, find the file called "ps3sixaxis_en.exe" and run it. Once you run it, you should get a small prompt window shortly. This is normal. After, reboot. 3) Once you've restated your computer, plug your PS3 controller in to your PC with the USB cable. To check that the controller is properly working, go to Control Panel > Game Controllers. You should see "PLAYSTATION 3 CONTROLLER OK". Now, click properties and test the controller's buttons and sticks to see if they respond. It should look something like this: Now, if you don't see the controller responding, you may have to calibrate it. Just click the settings tab and click "Calibrate..." 4) After all that's done, you need to install this custom controller config, so Left 4 Dead will recognize the controller in game. Feel free to change button configuration to your liking. The controller buttons may vary for you, so be sure to adjust it when you need to. Save the following config as "PS3.CFG" and place it in your C:\Program Files\Steam\steamapps\common\left 4 dead\left4dead\cfg. Now, add the following lines to your "Autoexec.cfg" file. If one doesn't exist, create one: 6) Start up Left 4 Dead and test your new controller! Enjoy! The only problem I ran into with this controller is that it tends to sway your aim around a bit, but it's really not noticeable.
