Portal is a first-person puzzle game. Players must solve physical challenges by opening portals to maneuver objects, and themselves, through the enigmatic Aperture Science Laboratories.
A simple Out-Of-Game Tool that let's you set options for multiple Source Games at once, and even let's you set options that are not normally available. Great for many uses. Note: I did not make this tool, and I am uncertain wether or not that it works on Linux or Mac, as I use Windows. The tool was originally uploaded on Planet Half-Life, and all credit goes to Kapitein Iglo, not me.

Now you can set options for multiple Source Games at once, great if you got new mods and games and don't want to launch them individually just to set options. Works with Mods too!
