Great detail.
Lots of fun.
Large area to explore.
Hordes attack from multiple places.
Spaced out supplies.
Have to explore to find items.
Nice spot for a survival map.
Cons:
Really easy. I got 11:31.07 on my first try with all bots.
Ammo is too close to good spots. I could just camp, and have no problems. For example, the room right above the trigger point is a great spot, with ammo right inside of it.
Special infected are useless. Too easy to kill them before they can attack.
Conclusion:
It's a great map, but a little bit easy. Other than that, I found that the infected could drop down from the ceiling, rather than just the walls, which posed as a small challenge at first. All I could suggest, is try to make ammo piles further away from small rooms, and possibly make more areas for special infected to attack from.
I hope you make a campaign with this type of map in it.
