Ok So I'm going to use this thread to ask advice on how to do things in my first Evil Fortress. I may link it to a community thread about my fort!
Here is my first question, I have blood gnats in my fort. I believe these are surface creatures. How do I get rid of them? I'm not sure how they got in. I have a single downstair entrance, which is walled off from the surroundings and has a hatch cover on it. The Hatch is not currently closed/locked as my garbage dump and atom smasher are up there. Did the Gnats come in via the hatch?
I guess they must have, unless they came up through a cavern before I covered that with a hatch but I thought them surface dwellers?
I'm also currently building a trade depot air lock. I'm not sure how effective it will be but there you go. Should I am to build a set of these near the map edges to get caravans out of the wilds asap? Also how to route caravans to the airlocks? I guess I need to have a depot accessible in each one?
Could I build a set of tunnels 3 wide from the one central depot to the map edges, each ending with a bridge? (The depot also kept separate to the main fort) that way the caravan can enter it quickly and I can close the bridges at once?
I need to read up on the wiki about the ai and pathing to see if the bad guys will try to wonder down the tunnels to the depot when the caravan is not on the map.
