Here's a base i built for my UNSC troops. Its actually the first base i've made that i like. I kinda got stuck on the name, because in Halo: Reach there is a bes called SWORD Base and in the books there's a CASTLE Base.
About this creation
Front "barricade" "door" "hatch" (whatever) is openable.

The back. I made it open cause this part is supposedly against a cliff. I guess that will be the v2.

The ops section of the base.
