This map has a discussion topic which can be visited here
I did not make this map. I was asked to fix the spawn points and missing textures. So I did. I give all the credit to the original mapper who created this map. I am just making my updated version available.
I want to use this opportunity to also discuss placement of Player Entities. There should be 64 units of space between any 2 or more player spawn points. The entities here were placed holding hands, and that cause at the start of the game for players to be stuck inside other players.
Also, please when level creating, use the no draw texture, and stick to the grid, this had to be some of the worst brush work I have ever seen. This map is still riddled with many of the original bad brush work and so forth.. I fix some of it to make the compile times less than an hour. Again I take no credit for this map and give it to the original mapper. I hope my fixes make the map more playable.
