About this map

A group of marines were hired to kill the aliens in a remote area of Black Mesa but they failed, now you and your squad are the last hope to finish the work.

What to expect

It is a single small map — the kind of thing you can finish in one sitting without planning an evening around it. The author rated it medium difficulty.

How to play it

  1. Press Host above. The map downloads first, then starts.
  2. Share the room link with whoever you want to play with.
  3. 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.
