The outside of the great wall of redteam, specially designed to keep out combine and rebelling nomadic war tribes.
A view along the wall, lots of space to move around. The wall is constructed of 2 layers of 2x1 3d blocks, arranged in the classic brick pattern. In the event one would get unfrozen, it would be next to impossible to remove it without taking out all the blocks around it, or destroying the block in question.
The longest crouch tunnel. Ever. I don't think it was used once. It is actually built inside the wall, to make things nice and self contained, and therefore goes right along the length of the wall.
The view from inside. Lots of space to move around.
The enemy base, just to show what it was pitched up against.
I REALISE THIS FORT IS USELESS. Sure, it confused the newer players, but when Beardchewer came in, he quickly caught on and rocketjumped in. It was also too close to the build wall; the enemy could have eaisily put a huge ramp up and just jumped straight in. Also, you can't see into the crawl tunnel except at the very end for the length of a single 1x5 meaning that even if somebody was stuck in there, you would have no idea and they could start sapping the wall from inside.
But it's pretty, right?
