I have another idea.

1: Put two bridges in an underground airlock.
2: Have two pressure plates to close each bridge.
3: Make dorfs put in walls and close off the airlock.
4: Flood the airlock.

I doubt this is practical, but I'll post a screenshot of my entrance later so I can get a clear plan.


If you intended to let the invaders trigger the bridges that'll be a bit tricky. The drawbridges will lower again as the pressure plates are no longer depressed (or 100 or so ticks later, whichever is the longer). To make the pressure plates raise the bridges and have them stay up you need to convert the on/off signal into a start only. There are a number of designs in circulation, I think, but I haven't used any of them. I'm using manual lever controls instead, with sacrificial doors to slow the invaders down.

The automation thing is why I designed the water trap I use. Gobbos get quickly flushed into a holding tank, and the who contraption works without dwarf/human input.

Plus hatches (along with doors and gears) some of the few devices that react instantly, which takes alot of guesswork (or minute planning) out of designs. Bridges have a delay, so it's quite a bit harder to make sure they do what you want.

P.S. I've had to modify the trap design somewhat to deal with the aquifer, but it's coming along nicely, I think. I'll let you know how it turns out.

I prepared all my squads.
All the archers.
All the macedwarves.
I knew it was going to be an unforgettable fight.
And then the caravan killed it.
