Birthday Gordon Player Model- Celebrating 25 years of Half-Life! addon

To use this model; open your steam library and go to Half-Life. Once you are there, right click the Half-Life tab, move your mouse to "manage" and click on "browse local files". Once there, simply drag and drop the "valve_addon" file into it and make sure you have load custom content enabled in your options menu.

Thanks and have fun :)
