Here is my rebuilt tower map: Download Link
It is set up to support free for all slayer, king of the hill and oddball games. There are no weapons on the map.
Important: Run any game variant at 75% gravity to ensure that the lifts work right.
This version is much more playable than the last. In addition to adding a third tower, I shortened the towers a little bit to keep people from hitting the ceiling as easily.
I've added survival features to help you live if you fall from the top. If you fall outside the towers, aim for the water - a teleporter should save you. There is also a teleporter in the middle tower that should save you if you fall there. The two other towers have 1-way shield doors that will stop your fall.
Please let me know if anyone comes up with some fun gametypes for this map.
