This is part of my BattleField 2142 collection. If you have ever played it or seen it played you know the tower has a place 
inside to climp up onto the plate forms. Well i didn't make the latter, Idk how to do that. So you can put a telly up on the platform
Instead of a latter. Or you can make the inside and a latter. Yes there is enough room for two MC's side by side on the platform. 
There are rails to prevent falling to your death.
