2. Minimum additional menus and buttons.

1.
Go here:

Do you have WinRAR? Extract it to the game folder, click HD3Launch, and play. It's very simple. If you need an executable to create a shortcut on your desktop, there's a button for that - create .exe

2. There are also very few buttons. It's better to see it once than to have it explained.
