SourceTV
SourceTV allows spectators to view the GravityGunOnly server without actually joining as a player. It allows you to either watch other people play as if they were actually that person, or they can use a free camera to move around the map as if they were in no-clip mode.
To use our SourceTV server, click on add a server to favourites, and then type “gravitygunonly.com” in the search box. You should see a server called “Gravity Gun only | SourceTV”. Click on this server then click on “add selected server to favourites”. Now, join this server as you would any other.
