This video demonstrates how you can perform the "fence bug", a useful glitch in Return to Egypt of Tomb Raider I Unfinished Business to use a shortcut.

This works in the classic version of the game and as you can see it also works in the remastered. (At first I thought it didn't but it turns out I was just a little rusty.)

If you want to learn more about the fence bug, you can look it up in wikiraider.com.

Basically what you need to do is stand in front of the seam of the fence, hop back, then sidestep twice, then turn to face the seam and aim past it (since I sidestepped right, face left past the seam) then simply run ahead and Lara will slip through the crack. It takes a little practice, but don't give up, anyone can do it.
