I am working on a new version of HackTheGame, which I lovingly call HackTheGame [Rebooted].
The game is under active development, but it’s up ‘n running. You can go here and register an account, create a server, download tools, send messages to other players, earn Bitcoin by doing tasks for Lord Nikon, etc, etc.
Be warned! This game is not a point-and-click adventure. You’re encouraged to explore.
The game has a Wiki which is a great resource to get you started.
For ideas, help or just HackTheGame chat join the Discord channel.
