Gunster: Rain of Bullets/Installation

The game must be run using Internet Explorer. Once you are logged into an account, and you click the play game image, the site will check your computer to see whether the game has been installed or not. If not, it will then prompt you to choose a path and then confirm the installation.

Note that the Japanese version requires an Active X plugin to be installed, titled something along the lines of Hangame Plugin. Also note that just clicking the play game button will not prompt you for the Active X, so you may be getting a strange "file is missing" error. Try going to another page on the hangame.co.jp website to recieve the prompt.
