Does NOT work on Mac ...YET.So you need the Java develpment kit if you are using the client.If you are on the webclient, you do not need to follow this guide.

Ok first download the client of Kabescape from the box at the forums home.The link just underneath the webclient.Then, Go to this link:
http://www.oracle.com/technetwork/java/javase/downloads/java-se-jdk-7-download-432154.htmland choose your operating system.Make sure you have chosen
YOUR operating system as it would be a waste of time just downloading the other system's development kit.
After it has downloaded the setup, run it and just choose which things you want installed.The tutorials can be skipped because it only guides you to writing Java.You can download them if you aspire to become a developer.
Then, open the Kabescape folder and click
Compile.exe. It will open the CMD window and then close again. Then click run ( depending on your operating system) and the client should start in a few second and then you're ready to play!
Additional Details (must-read)Your operating system can be found by right-clicking MY COMPUTER and clicking properties.Then find your operating system under system type. If you are on a Linux, find your system type and download the linux version form the downloads page.The same goes for windows.
Attention Windows UsersYou will have only 2 possible system types.
1.32 bit operating system.(in the downloads page, click
Windows x862.64 bit operating system ( in the downloads page, click
Windows x64I would still advise you to use the webclient as it is more easier to operate to and use.
But best of luck with my guide.
Point out any negatives in my guide.I appreciate them.
