Installation

Everything you need is included in one ZIP file. Simply unzip the file directly into your Heretic II directory on your harddrive (usually C:\Program Files/Heretic II/), and all the correct files and directories will be created.

The ZIP file will create a new directory called Lanius. To run the game, simply double-click on the play_sslayer.bat file under /Heretic II/Lanius/. Or use the shortcut called play_sslayer.lnk, which you can copy to your desktop (if you have Heretic II installed in C:\Program Files\). Starting the game any other way will not display the correct in-game messages, and some custom sounds won't work.

By default the game starts with an 800x600 screen in software video mode. A crosshair for aiming spells and weapons will appear (with auto-aiming off) and the blood level will be set to ultraviolent. You can change any of these defaults using the menu system, and your own settings will always be loaded from then on.
