We (Myself and HighVoltage) are currently working on adding some more nodes to the map and we should note that we already, (if you didnt realize) added nodes so helicopters, dropships, and gunships can fly around the map, and Fast Zombies can now reach you nearly anywhere, including buildings, since we implemented Climbing Nodes.
At one point the idea to add climbing nodes to the skyscrapers came to mind... which brought up two problems:
1. The Fast Zombies would not target you from that high up.
2. If you had Fast Zombies climbing skyscrapers (successfully), it would be both unrealistic and funny as hell.
On a seperate and slightly less humoring note, I finally got the Nightly Build Archival and Logging system up, so when HighVoltage goes to sleep, he uploads the most recent VMF for the map and the system will log when he uploaded it, while simultaniously backing up the old VMF in case shit arose on both his computer and the VMF I work with, which is highly unlikely.
