This is the server's map as the compiler left it: the real textures and the baked light straight from the .bsp, in your browser. The camera flies a loop over the places worth seeing; when players are in game and the map matches, they show up where they stand. It is a picture of the map, not the game: nothing here is the server.
A lighter copy of the map loads (smaller textures, no props). Drag to look around the current place, pinch to zoom. The flight runs by itself; tap Pause to stop it.
mR Live shows the same players on the top-down map with the chat. The archive has 29,665 saved builds from 2008–2010 to place on freespace. Join the server: connect mikes-revenge.net in the HL2DM console.
