Lots and lots of traps....
I had no weapons left so I ran around trying to ram people, why not right. I turn a corner and ram this guy and then the traps come into play.... lots and lots of traps....
I'm really of the mind that they should be toned down some. Higher cost, only 1 trap can trap one person (as they are 1 trap can capture 3 or 4 people at once).
That still would not have helped me as I got snagged by lots of them and with no weapons left I could not get away from them.
