I did not include with the source code most of the images and icons used in the game. As always, fair usage, like mentioning it's based on Legacy, is OK. In other words, please do not name your game server 'Hacker Experience Continued' or anything like that. The MIT license does not give you the right to use the brand Hacker Experience commercially, which is a registered trademark. You can run your own private game server and display ads or charge money however you like, with no ties to me and/or Neoart Labs. Legacy is published under the MIT license, as described in the LICENSE file. REDACTED will contain placeholders for API keys and passwords that you might want to change. Make sure to scan the code for the words REDACTED and 2019. I can't guarantee fast responses, but I'll try to help you as soon as possible. Your question may be someone else's, so do not hesitate asking it. If you have questions and/or need help setting it up or understanding its code, please open an issue.

A model of the cron file can be found at crontab. You can build the database schema from the game.sql file. Legacy uses PHP 5 and MySQL, alongside some Python 2 scripts running on cron jobs. I also added translations to comments in Portuguese (except for the ones I had no idea what I wrote originally). I did a quick code-review and added some comments that might help you understand the code. This is the exact same code that powered Legacy, except for a few hard-coded passwords and API keys that were replaced with the REDACTED strings. Keep in mind it might be outdated, but it's better than nothing. The closest I have to a documentation can be found at the info/ folder. In fact, it's more likely it will not work as expected. It has no tests, no architecture, virtually no documentation and no warranties that it will work as expected, or in a secure manner. If you were one of these players, I hope you had a good time with Legacy! I also hope that, by releasing its code, someone else can maintain a server on which you can keep playing it. Context about why I decided to shut it down. Legacy reached the 1-million registered players milestone 5 years after it was released, and soon after I decided to shut it down, since I no longer could maintain it. I made a promise I'd release it and here it is. This is the source-code for Legacy, the first version of Hacker Experience I built from 2012-2014 and published on 2014.
