About this map
What to expect
It is a single medium-sized map, playable in one sitting. The author did not record a difficulty for it.
How to play it
- Press Host above. The map downloads first, then starts.
- Share the room link with whoever you want to play with.
- They open it and join — no install, no account, no port forwarding.
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.
