The walkway_gate_b model, but with brushwork to make it look like walkway_gate_a. Useful for little details like the stripes falling off. Place the .vmf in the bin/Prefabs folder of Portal 2

This is the second map in a series that began with 'Sphere of Roundness' last week. Version 2.0 of that map is also included in this release, they also transition into each other to make a loop. This time I decided to focus on a single gameplay element for an entire map rather than trying to use every feature available. The map also follows the loose premise of "What if aperture had tested faith plates in the 1950s?" the default faith plate model stands out a little in the underground, so I went for an alternate appearance, see what you think! I have a feeling it is a little easy, but that is mainly down to the overall design, so my next map will aim to be a bit tougher. Sphere of Roundness: I got a huge amount of good feedback for the first map and made a few changes to fix exploits and also clean up the edges a little now that the full SDK has been released. For a full changelog see the readme! Screenshot: http://img339.imageshack.us/img339/6006 ... 400001.jpg
