This Half-Life 2 map is my current project. I am also using this level as part of my project in lieu of thesis.  The project focuses on communication through form with a virtual environment.  The setting for the level is an industrial section of City 17.  The main objective of the level is find the airboat on the other side of the Water Station.  The critical path directs the player to three different major areas and the players actions and decisions were observed for purposes of the project.
