This map is very good and unusual, with two usable miniguns (cover the minigunner's back!) and an automatic artillery cannon. You may notice some visual bugs, like dead Zeds freezing in mid-fall, but nothing that affects play enjoyment or pathfinding.
The red trails indicating the trader location are a bit misleading, as the trader always appears in one location, under the helicopter, but she is visible even without the trail.
Tested with Doom3KF, TheBrute and ServerPerk mods.
