I found a way to keep all the women in Duke Nukem safe from gunfire,
You must have the shrinker and freeze gun to do this. 

Step #1.   Shrink the dance/hooker/cheerleader/captured woman, (from a safe distance) and 
aim down.

Step #2. While she is shrunk , shoot her with the freeze gun, you should hear a scream and 
see a piece of flesh fly off of her.

Step #3. Allow her to return to normal size, shoot her , kick her whatever, she can not be
hurt. She stills performs her funtion (stripping ,moaning, etc.)
