This is an old one I explored a while back in singleplayer that I liked. It has 32 Player Spawns and also has traitor traps as well as airboats.
This is a series of videos I watched a while back that had some interesting information on how some of the music and sound effects of Half-Life and Portal were made including the sources of samples used in them as well as the actual instruments themselves. I figured ya'll might appreciate it...
