Using the game's installer I was able to extract a swf that had less protection than the one on the site.And so I was able to extract the source from the client using other programs.There's still a lot to do to get this to run as a pirate server, but maybe it's a step to create a bot, hack or something like that.The extracted project only runs in Adobe Flash Builder, but I couldn't find it to install.
