Not sure if this is useful for anyone, I just discovered this while trying to run Gemcraft 2: Chasing Shadows standalone to squeeze maximum performance with extreme gem bombing. Anyway, here it goes. Go here to download the standalone flash application. http://www.adobe.com/support/flashplayer/downloads.html Select the Flash Player Projector that is appropriate for your operating system. For example, this one is for windows Run the flash standalone executable. File -> Open Enter this URL. It will be saved next time you want to open it: http://live.cardhunter.com/client/CardHunterWebApp.swf Note: The flash cache for the standalone client is separate from the browser's cache. You will have to save your account info/changing settings again You can open this URL in a browser to launch CH without checking for server availability The URL for launching gemcraft with Armor Games authentication is also shown in the screenshot in case you're interested Finally I can have full screen without that annoying chrome pop-up Have fun hunters !!!
