What the developers have to say:

Why Early Access?

“The game is in a good state in our opinion, but it's not yet where we want it to be for a full release. We feel like it's time to finally go public to attract more players, asset creators and developers to bring the game to its full potential.”

Approximately how long will this game be in Early Access?

“This heavily depends on the number of volunteer contributors we can attract and how much time they will be able to spend working on the project. We're aiming for a late 2018 or early 2019 release of the full version that satisfies our standards. Development will continue after this to further improve the game over time.”

How is the full version planned to differ from the Early Access version?

“Here's a list of what we currently have in plan for the full version:

  • Port the game to the newest Source Engine version. Besides resolving a couple of engine limitations, this will also make it possible to release native macOS and Linux versions.
  • Create a web application that allows communities to easily manage competitions and track match statistics.
  • Include more maps, team kits, balls, shoes and keeper gloves.
  • Smooth out the current animations and create new ones for actions (shots, headers, dives, etc.) and celebrations (including lamenting).
  • Translate the game to more languages.

What is the current state of the Early Access version?

“Please see the "about this game" section for features that have already been implemented.”

Will the game be priced differently during and after Early Access?

“The game is and will stay free.”

How are you planning on involving the Community in your development process?

“The game has been heavily community driven since its original release 15 years ago. We're constantly in contact with the players through Discord, the forums and in-game. Every player has the chance to get their voice heard and steer development in the direction they feel is best for the game.”

IOSoccer Update - 20 June 2018

  • Removed versioning in default map names. (eg. 8v8_vienna_b6 becomes 8v8_vienna) This to prevent servers from not auto-starting when a map name changes because of an updated version while the old version (which would be the default one) gets removed.
  • Updated in-game languages for the following: Danish, Dutch, French, German, Italian, Korean, Polish, Portuguese, Russian, Simplified Chinese, Spanish and Swedish.
    NOTE: Brazilian-Portuguese is not supported in SDK 2007 and therefor it still will be English.
    NOTE2: Not all languages are translated 100%. The remaining English texts will be translated in the near future.

About This Game

IOSoccer is a free non-commercial competitive third-person online multiplayer soccer game that offers unparalleled freedom in ball control and gameplay depth. Originally released 15 years ago under the full name International Online Soccer as a Half-Life mod, the game was later ported to the Source Engine and re-released in 2008. Since the last public release, the game’s code has been completely rewritten, new player models created, and countless new gameplay features added.


  • Unparalleled freedom in ball control and gameplay depth: The combination of a third-person camera together with mouse and keyboard input gives you full control over your dribbling, shooting, and passing.
  • Skill moves: Show your mastery of the game with bicycle kicks, diving headers, ball flicks, and precision dribbling.
  • Flexible team sizes: Whether you prefer 4v4 street games or our standard 8v8 matchups, we support everything from 1 to 11 players per side.
  • AI and human goalkeepers: You can let the server control the keeper or take its position yourself on the fly.
  • Public matches: Join and leave public servers with casual matches whenever you want to.
  • Competitive matches: Participate with your club, national team or mix team in leagues and cups organized by the community.
  • Dedicated servers: Use our official dedicated servers or rent your own one from a hoster of your choice.
  • Player customization: Set your shirt name, pick your shirt number and choose your ethnicity, hair style, shoes, keeper gloves, ball, and sleeve length.
  • Instant replays and highlights: Watch goals again from the TV camera's perspective right after they happened and use intermissions to catch up on chances you missed.
  • Goal celebrations: Choreograph your team's goal celebrations with various animations.
  • Warm up mode: Practice shots on your own goalkeeper during warm up before the match where every player has their own ball.
  • Custom assets: Make your own maps, team kits, balls, shoes, and keeper gloves.
  • 100% free: No microtransactions or any other hidden costs.
