Yeah I agree this glitch is good but it would be better if we could knife them everytime instead of hitting the bars. The golden spork would make rounds go by really quick and easy. Btw you can charge the Hells redeemer 3 times.
I know mate, I'm doing this glitch again right now and I'm on round 41 at the moment. I charge the hells redeemer 1 time and it kills 6 zombies just like if I charged it 3 times. That means you can kill the same amount of zombies in less time
