This one is a campaign rather than a single level: it spans 7 map files that run in sequence, so expect to play it as a session rather than a quick round. The author rated it hard, so it is better suited to a group that has played a few maps together already.
The parts run in this order: kh1, kh2, kh3, kh4, kh5, kh6fix2, kh7_preview.
This map is not stored here in advance — it is fetched when you press Host and then starts. That happens once; there is still nothing to install. Everyone who joins needs a browser and the link, and nothing else — they do not need to own Half-Life, install the Sven Co-op client or make an account. Because the connection is brokered for you, neither side forwards a port or rents a server.
