Tanks!!! Multiplayer

This is supposed to be a demo for Unity's multiplayer capabilities, to convince developers to use Unity over competitors (I assume Lumberyard?). But I've never seen a server running, to be able to join a game. There's an option to host one yourself or play single player, but as a developer I wouldn't plan to make my players host. Anyway as a multiplayer capabilities demo it's a complete failure. As a game in its own right? I haven't played it much (single player) and don't expect to... looks pretty generic.
