This is a pretty unusual map that adds another dimension of play to Sauerbraten.
The walls are ladders most of the way up, so at least half of the fighting is done on almost vertical walls, which adds a lot to the gameplay. There is 1 quad, no healhboost, and lots of ammo and armour. It's a pretty loaded arena. It's also extremely fun for insta, because you don't just have horizontal fighting, you have people crawling all over the walls. Or rather, flying all over them, since you can move up the walls very quickly.
