I started making a map of Seaholm Power plant one year ago. That project was interupted when I was asked to make a map for Fantastic Fest. However I am happy to say that work has resumed on this project.
The Seaholm Power Plant is a incredible 1950's art deco power plant located along the river in Austin, TX near down town. The power plant was a gas/steam turbine plant and ran all the way into the 1980's.
For the game I am reviving the plant from its current empty state. This will be a four map campaign for Left 4 Dead 2.
The following are screenshots of the Seaholm pump station and surrounding walking path along the river. This is the first map and current area I am working on.
