How to create a Sven Co-op server in ProximaClient
Your own Sven Co-op server means co-op with friends: fighting through maps together against Half-Life's monsters. In ProximaClient you can set one up on your PC in a couple of minutes: no hosting to rent, no manual SteamCMD setup, no config editing. Let's go through how to create a Sven Co-op server in ProximaClient.
What you'll need
- A Windows PC and ProximaClient.
- A ProximaMP account — if you want to open the server to friends through a public tunnel.
Creating the server
For Sven Co-op the creation window is shorter than for other games: the game has a single build, Vanilla, so there's no Build step.
- Open ProximaClient, go to the Game servers screen — the gamepad icon in the left menu — and click Add server.
- On the Game step, pick Sven Co-op and click Next.
- On the Setup step, enter a server name and an install folder. So that friends can join without a public IP or router setup, turn on Create a public tunnel for this server.
- Check the summary on the right — the folder and the build can only be changed by recreating the server — and click Start server.

ProximaClient downloads the server files and starts the server for you. More about the creation window in How to create a game server in ProximaClient.
How friends join
Send your friends the server's external address — the public tunnel provides it. Then each of them launches Sven Co-op, opens the console with ~ and types the full address:
connect server_address
If the console doesn't open, add -console to the game's launch options: in Steam, open Sven Co-op's properties and put the parameter in the launch options field.
What you can configure in ProximaClient
Once the server is running, you manage it right from the app:
- Players — the list of who's on the server right now.
- Maps — change the map and set the starting map in the launch options.
- Launch options — slots, port and address, VAC, custom parameters, auto-restart on crash and autostart with the app. The server updates to the latest version via Steam.
- server.cfg — clear fields and toggles instead of manual editing.
- Console — command hints as you type, your own quick commands and log filters.
- Scheduler — backups, restarts and console commands on a schedule.
- Server files — create and delete files and folders, an editor with syntax highlighting.
- Monitoring — real-time CPU and memory load.
All features are on the Sven Co-op server page.
