Can I add custom community maps to my server?

Not on the current release. Delivering custom maps needs a FastDL host, which is not wired up yet, and GoldSrc has no Steam Workshop. Your server plays the official maps that ship with the game, so no player gets a missing-file kick.

Do my friends need to download the maps?

No. The official co-op maps come with every Sven Co-op install, so anyone who owns the free game already has them. They join by IP and start playing.

How many players can a campaign hold?

Up to 32 on the large tier. Small holds 8 and medium holds 16. Difficulty scales up with more players connected.

Best Sven Co-op maps and campaigns to play (2026)

Updated Oct 11, 2026

Sven Co-op turns Half-Life into co-op. Up to 32 players fight the AI together, no PvP. Around a hundred official co-op maps come with every install, so nobody downloads anything to play them. This is the shortlist worth loading first, plus an honest note on custom community maps.

Campaigns you can pick at deploy

These five load straight from the deploy form. Pick one as your start map, then the server rotates or you change level from the web console. All of them ship with the dedicated server, so every player already has the files.

Sven Co-op: The original campaign (svencoop1 into svencoop2). The classic first run for a new group.
New Hope's Last Stand: A four-part defend-and-survive series. Good for a bigger squad that wants to hold a line.
Crystal: A two-part co-op map. Short and self-contained.
Infested: A two-map co-op series.
Sven Co-op Tetris: A six-map series that mixes block puzzles with heavy combat. Plan on a couple of hours.

Loading any of the built-in maps

Beyond the deploy picker, the roughly one hundred official maps are all present on the server. The easy way is the map picker in the web console on your server page. From the game, open the console with ~, log in once with the RCON password from the server card, then prefix each command with rcon. Use status first to confirm the current map.

Custom community maps: the honest part

Sven Co-op has thousands of community campaigns, but two facts decide what you can play on a hosted server. First, GoldSrc has no Steam Workshop, so there is no subscribe-and-go. Second, delivering custom maps to joining players needs a FastDL host, which the first release does not set up. So a hosted server plays the official maps that ship with the game. If a campaign is not in the install, players cannot auto-download it here yet. Stick to the built-in list above and you never hit a missing-file kick.

Difficulty scales with your squad

Modern Sven Co-op has no easy or hard switch. It scales with how many players are connected, so a full lobby gets tougher enemies. Pick a bigger tier for a bigger group and the maps push back harder on their own.
