This is an interesting map, way different than most of them out there. However, there are some issues:

I like the fact that you have to do a huge scavenge hunt to grab objective items, and that there is no step by step guidance to achieve that. However, since you have to do small bits of parkour to bring the items back, it's very common to see players fall to their deaths and then the items become unreachable.

Basically, if someone falls down and dies in while doing parkour and carrying an item, the map is completely softlocked, no more progress can be made. To fix this, you should add triggers at the bottom of each parkour section so that when an item falls down it teleports automatically back to its original location.

After that, I've also noticed that compass markers that point towards all objective items, like the yellow arrow that shows you where the baby is, don't disappear once you place the item in the corresponding pedestal. This leads to having a compass cluttered with arrows that don't server any purpose and they end up confusing players. I suggest removing the glows and arrows of each objective item after being placed in their pedestal.

Additonally, you can jump on top of a zombie and then on top of the columns to reach the baby faster, without having to go through the intended route. Maybe adding some obstacles to block players from jumping up there will fix the issue.

Finally, there is not much of a challenge in general. Zombie spawns are low and they don't seem to respawn after being killed. The map eventually becomes a walking simulator, similar to what happens in nmo_outbreak_0101. Increasing zombie spawns a bit and enabling respawns should increase the challenge a bit.
