Tips

You will need to be in Blade Mode to slice off any limbs. The best way to get an arm off is to aim for the wrist area. Use a stealth kill for the best results, as this will make it easy to line yourself up. If you are in a group of enemies, take out the other guys first so you can focus on the Lefty. If you are having trouble cutting off the arm, you can always restart from your last checkpoint.

This cyborg is found after you find the second hostage. Don’t worry, its arm will respawn as part of the story event. It will still count as long as you cut it off once.
