I do not know if it is really that impressive, but I am trying to build the ultimate defensive works near my colony. Over time, I want to improve them with advanced technology, but I expect that the patches of the 1.0 unstable won't give me the opportunity to do so. Here is their status so far, the point of them is that they pretty much cover every approach to my colony, and give my characters a fair bit of defense in depth. So far, these defenses have stood up to all the attacks, for example, in the case of bomb-throwing enemies, I can command my characters to retreat to another line, or go into the tunnel and attack the bomb thrower from the flank. I want to dig out another tunnel from the hill to the south, fortify it, and use it as a more effective flanking point during battles. I will probably include a first aid station close to that tunnel, as my current hospital is too far away to quickly remove and tend to injured characters during and after battles. There aren't enough traps to really do that much damage, however, so I will probably increase my trap line from two to four, maybe six, if I can find the wood.
That's the problem really, you can't get the wood you know.
You know Henry Crun? He is a guy who can't get the wood either.
