This is a simple, step-by-step tutorial on how to install and start the game. Note that playing the game is completely free and does not require any sort of personal or payment information to be entered at any point.
#1 - Install BYOND
BYOND is the game engine software that Sigrogana Legend 2 runs on. Go here;
http://www.byond.com/download/
Download the latest version for your OS and install it. BYOND is completely safe and doesn't install any unwanted bloatware/spyware/etc.
#1.Optional - Register BYOND Key
You can register a BYOND key, although it isn't necessary to play the game. However, your BYOND key is displayed in global chat with other players, and if you don't have one, your name in global chat will show up as 'Guest-(numbers)'. Registering a BYOND key is free.
#2 - Navigate to the game page
You can find that page here;

If you want to learn more about the game, the above link contains some basic game information, screenshots, and other stuff.
#3 - Join the server
There should be a server listed with a 'Join' button next to it. Click it. You will probably get a prompt asking if you want to let BYOND run; click yes. The game will then open and begin download the game's resource files. Once complete, the game will launch in a window titled 'Sigrogana Legend 2'.
#4 - Have fun!
Click the title screen and hit 'Create' to start a new character. You should see a tutorial message on what to do next. Enjoy!
