VEIN Multiplayer and Co-op Guide
VEIN's persistent zombie-survival loop rewards a group that treats the base, supplies, and server as shared responsibilities. Use these roles as conventions; they are not a claim that the game requires a fixed class system.
Useful group roles
| Role | Focus |
|---|---|
| Scout | Maps routes, reports threats, and brings back location evidence. |
| Quartermaster | Organizes shared food, medical supplies, tools, and emergency reserve. |
| Builder | Keeps the base accessible, defensible, and easy to extend. |
| Vehicle/transport lead | Coordinates fuel, recovery, and return routes where the current build supports them. |
| Server operator | Handles access, backups, updates, logs, and join tests. |
Start and end each session
- Set one objective and say what resources are communal.
- Keep a recovery reserve before leaving the base.
- Run difficult expeditions only after the current save is backed up.
- Return critical gear to marked storage.
- Report errors with build, time, player, and location.
Dedicated-server routine
Use the setup guide to prove a single join. Then test save/restart/reconnect before the group relies on the world. Keep the branch and build visible in the group chat, because VEIN has main and experimental lines.
When co-op feels unstable
Compare one player's symptoms with the rest of the crew. If everyone pauses, inspect the server process and logs. If only one person fails, inspect their route and client. Use connection checks and troubleshooting.
