This is an old map from 2003, try as I might I couldn't find any contact info for the original mapper... but I've got feelers out to locate him.
If it is a him, nicknames can be so gender neutral.
This is a mine with tracks on both sides that end in walls. Originally the map had instagibs only as the weapon, but this didn't strike me as the ideal environment for that. I replaced 2 of those with redeemers, rocket launchers for the other pair, plus added miniguns and pulse rifles. Switched up the redeemer to respawn faster than it usually does to boot.
Combat is fairly intense here...
...but there are elements of the map that keep it somewhat well balanced.
Map has 4 mostly transparent barriers, 2 in the middle and 2 others near the flags. You can see them if you look for them but they're easy to miss.
