Typically, the majority of Trespasser game files remain on disk and are read from there during gameplay by the cd-rom. There is, however, another option. Generally referred to as a ‘harddrive’ installation, there are several beneficial reasons for installing the game in this manner. Some of those benefits are: allows you to play the game without aid of the cd-rom, thus allowing a user to store the Trespasser cd instead of subjecting it to potential damage due to useage, smoother gameplay during audio calls, and perhaps mostly importantly, a harddrive install allows a player to enjoy the use of TresEd (Trespasser Level Editor) as an editor and not simply as a viewer. You will not only be able to edit the game’s levels on your own, but the harddrive install will also present you with the ability to play and enjoy an ever growing list of fan levels created for the game. The information that you will find below will guide you through this simple process.
