I will add that to the list.
Also you can make big wall to separate the cage of the TDM in half and make sort of a church in the wall with a door to the other side. (you need to make them look the same but leaves on trees would be red and so on) So, you can make an opposite world. (you could dupe this, turn it 180 degrees, build wall, church, door then re-paint the opposite side.
SO this can be an ulternate dimesniona War with 4 teams! 2 teams every dimension (2 dimensions) and 1 team every area. (2 areas, under and above ground)
I'll think of team names.
