I did actually look at them but in 28mm they are hugely boring. Just a great slab of grey.
If broken down into rooms then you could I suppose fight through it, but they were never raided, they just held out and surrendered intact and largely untouched.
Even post war the attempts to blow them up where ineffective. So much so they jsut buried the remains of the Berlin zoo tower after failing to demolish it properly.
Even reduced in scale they are monstrously tall.
