Quake II was developed by ID Software and published by Activision. The author of the custom level I'm playing is Alex Richardson. I own nothing in this video.
Crater's Edge is a short but well-crafted and satisfying sewer-themed level with complex architecture, great lighting and well-made layout. Along with Waste Pumping Station it's got to be one of the most faithful to the feel of the waste unit of the original campaign. Its single official secret is one of the best I've seen, for not only does it reveal an entirely new area, but it also allows you to take a completely different path leading to the bridge (your first mission objective), and it also acts as a shortcut since you can avoid killing about 10 or so Strogg by taking it.
