So, my current world has 4 aggressive races that are active every season. Obviously, I'm going to have a big meat grinder on my hands.
I decided to make my fort a big death trap, with tons of different manual trap systems that invaders must get across. For example, simple things like bridges dropping invaders down shafts, to more fun things like massive drowning towers (yes, towers). Any invaders that are let past the traps will just be caged or shot.
However, my creativity when it comes to DF traps is fairly limited. I was wondering what kinds of things you guys could come up with? I'd prefer nothing that involves a bunch of pressure-plate and water systems.
Still, I'm gonna be uploading this map whenever I'm finished with it so please post any ideas you have. I don't have magma, sadly.
However, I have a river and I love working with water, so any traps involving water are greatly encouraged. Currently my drowning chamber will function like this; baddies enter at the bottom of the tower, the exit is at the top. Water is pumped from a reservoir below the tower up above to a hole where it can shower down into the chamber. As the baddies move around a spiral staircase to the top, the water level slowly increases till it drowns them. Once it reaches a certain level near the top, a grated off pressure plate will activate the trap doors which will let the water back out into the reservoir.
If the baddies can outrun the water they get to live for a bit longer.
Anyway, what other ideas do you guys have? I'll also be making a massive flooding machine which can flood my whole fort just in case anything bad happens (I get bored).
