Here an example on how it works. (Unfinished Business, Return to Egypt) On one side in the first chamber you can climb onto a platform with a fence and some windows in the wall through which you can see a panther. You can use the fence bug here to get through the fence.
How to do it
- Position in front of the fence, where two fence panels are joint.
- Jump back so that you are one square away.
- Take two sidesteps to either side.
- Turn to exactly face the gap in the fence, or a bit to the left, then run forwards to get through.
