We are glad to announce that after two weeks of closed testing, the Screeps standalone server is live for public testing, and the entire code is posted to our GitHub and available to all!
Now you can install the server on any machine from the NPM repository with a couple of commands. Please see instructions in our README.
Within a couple of days, we plan to set up integration with the Steam Workshop to let you upload your mods for the community.
Besides, after negotiating all the details with the Steam marketing team, we have agreed on the date of making Screeps available on Steam as "Full Release." If everything goes as intended, the release will happen in a week, on November 16! The game will exit the Early Access status and be published in the main catalog of Steam games.
