Yes im sure shadeblack. I've been through the game three times. Once to harvest all the little sisters, the next to save all the little sisters and the next to do nothing to the little sisters except the first one. But anyway there was a glitch. I just took down a big daddy, i walked over to the little sister and harvested her…..then the same one appeared in front of me again so i harvested her again!!!
I used the wrench on everything except the big daddys…..they deserve incendiary bolts and exploding bucks!!!
Using full research and wrench jockey 1 and 2 and research bonus tonics, the 2 swing faster tonics plus the gain health when do damage with wrench tonic, (i forgot the names)…..taking down every enemy besides big daddys is a breeze…..you just keep hitting them in the head with the wrench, they get stunned and u keep hitting them over and over…..while gaining life.
