This is the java-based game client. It requires java runtime 7 or later to be installed on your system.
Step 1: Install a Java Runtime Environment (JRE), version 7 or later.
In order to check if Java is already installed, type on the command line:
If Java hasn't been installed yet, execute the following command:
sudo apt-get install default-jre
This will install the Java Runtime Environment (JRE).
Step 2: Download the game client. It is an executable java archive (jar).
Step 3: Start the game by double-clicking on the downloaded file "Darkfire RPG 1.1.0.jar".
In case double-clicking doesn't work, you can alternatively type on the command line:
java -jar "Darkfire RPG 1.1.1.jar"
