The basic premiss of the map is that the waring groups must fight across a Xen no-mans land, while having their respective based on Earth. Also, I wanted a map that allows players to stock up on ammunition before going back to the fight instead of running around for two minutes trying to gather weapons. I enjoy the "story telling" aspect of the original Gearbox maps and wanted to continue on that theme because I feel that it adds greatly to the overall experience.
This is my third map to be released. This map maxes out just about every limit the HL engine has. I could not add any more brush based entities (no more glass or grating or "trimmings"), I have reached the MAX_CLIP barrier (no more floor space can be added), I am extremely close to the MAX_PLANES limitation of Zoners HL tools (no more complex world brushes), and Im am very close to the MAX_TEXTURES limit of Zoners (3.28 of 4 megs). What does this mean? The Xen area was meant to be twice as large and there were going to be many more warp destinations, but the limitations forbid it from being. I had no way to Beta test this map with a large crowd, so take it as is. I plan on making a sequal to this map which is only on Earth. That will allow me to make more areas to hide in and lots of passages, in addition to being able to warp back and forth with many more destinations.
