Pros: Detail, fun to play
Cons: Red can defend too easily on roof, and inside building in certain spots.

On the roof there is a very certain spot that only scouts can get with double jump. Its looking out at the front. You can see it in the picture.
Improvements: Needs a super secret bs1 is cool room. (not serious, but you can add one if you want)
Notes: Very fun map, cant wait to play updated versions. The map can only get better. (hopefully)

I had it added to the server i am admin at, and we needed to buff up the zombie start limit to half the players (at the time was 9) just for the zombies to win.

No exploits that i found while playing.

-------------------

I have to re edit since you can't double post. I have been thinking, but the side objective isn't that important for defenders. The bell right now takes a bit to get to, and when you do hit it, you spawn in a basement that is barricaded in. So as zombies we usually just avoid hitting the bell since 1. We are already inside the building, 2. No one will probably be hiding in the basement, and 3. Too much of a pain to get out of basement.

Maybe you should give more incentive for hitting the bell, or make hitting the bell easier.

One good thing about hitting the bell is that you can no longer be camped at the gate. Its easy to avoid dying though by going into the trees, but if they have a good sniper, its a lot harder.

Those are just some thoughts i have been having, but at the moment it is still my favorite zombie fortress map.
