It's almost done. I'm disappointed that not a lot of people are enthusiastic about zombie maps, it's a good gamemode. :/
I intend for players to take the left path down to the flag. The first right path has a pit right by the wall, so it prevents M79 boosting. Unfortunately, in further testing, it doesn't prevent double nade boosts, but even after that, the gap from the mine tracks to the flag is too large. Boosting won't work, falling down to that path from the broken bridge won't work. All thanks to extremely limited amounts of jet.
Here's a -low- quality screenshot of my progress. I've improved the map a bit since after that screenshot was taken.
