Oh God, this tip would really have made things a lot easier for me. Can't believe I didn't think of it myself. I was always in such a rush to wrench them once they got zapped.
The Frozen Blast plasmid wouldve worked too =P
I wonder if there is going to be any sort of upgrades or tonics for your SkyHook? The wrench in Bio1 had some great tonics you could use with it. Using it to freeze foes was awesome.
