For those of you that don't know what this is, it's a combo application for Halo CE. It consists of a sightjacker, will allow you to change your Field of View and will also allow you to play the game in third-person.
Copy the STL.dll to your Halo CE root directory (with haloce.exe), on your first run you will encounter an error saying it can not find path.ini and Strings.txt, just run the application and click on the settings button, next click okay and the files will automatically be created for you.
