Unused elements
These chambers are a tutorial/introduction to three test elements that Valve created, but didn't use in the game. The test elements shown are the Pneumatic Diversity Vent, Paint Fizzlers and Reflection Gel.

Carl Kenner's style mod was used to allow the use of the fizzlers and gel in the PTI.

BEEmod was used to add the vents as well as the doors, crushers and other minor items.

I really liked the valve usage in the first room. Nice!

The first section was decent. Got a lot of bullet holes on my vest from those little guys, but otherwise it took me a few seconds to figure out the "reverse-psychology". After that a few plays here and there and got through. The second section was easy.
