With forums back up, I am back with another map suggestion! This map is called trade_mymind. Link's here:
http://tf2.gamebanana.com/maps/173832 . The map in the beginning is like abstract, but it's not entirely like that. There's no easter eggs that I could find on this map, but there are 2 teleporters. One teleporter leads to the classic boxing ring, and the other leads to a room where you can worship Gabe Newell, have books, look at animals or look at ponies (although I must say, it's a trap!). Some posters in the room with books, Gabe Newell, animals and ponies may do something when you shoot it. For example, walking up to the mighty pope Gabe Newell will play a Hallelujah in the background followed by an explosion. Anyways, that's pretty much the map. It doesn't look like it'll do much damage, but I have my fingers crossed.
