This was my second map relesed for HLDM. It is a chemical processing building with lots of sneaky spots, ambient sounds, and details. There's a small court yard, but the bulk of the map is indoors.

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.

This map is roughly based off of my favorite map of all time: Op4_Yard. I have attempted to keep the basic layout the same and yet make something very different. It is the first Op4 Rune Arena map I have made, and as far as I can tell, the first one ever created. The ability to add Runes into Deathmatch was added shortly before Op4CTF was broken by Steam. The map contains six Runes, Four Armor Runes, an Ammo Rune, and a Damage Rune. Kevlar is designed to run with MP_Multipower set to either on or off, but it should be noted that with multipower on, a single player could load up with armor, damage, and ammo runes which could be very un-fun for the rest of the players.
