We haven't updated this game from v1.37 to v1.39 yet due to various revisions to the Steam backend which requires us to migrate to the latest.

But even though v1.39 is not a major update, we are still looking into getting it migrated in the coming weeks. At which point we may also release the scripting system allowing you to create your own missions.

And in case you were wondering, these are the only things new in v1.39

1.00.39 | 11-09-10

• Minor string localization corrections.

1.00.38 | 03-23-10

• [MP] Revised handling of stats server update
• [MP] FIXED: Joining a game from the GameLobby caused chat messages to be duplicated
