Harbor Cage Glitch. MPO+.

OK, this time I will show you how to get inside the cage at the harbor. I get asked how to do this so many times, and it's really easy.
OK, first of all you are going to have to head over to the ramp next to the cage and dive roll off of it to get on top of the cage.
Next you will have to stand so you are facing away from the ramp. Now make sure that you're right at the back of the cage, and also look at where your foot is. Your Left foot should be on the line that connects the cage to a container.
Now go into first person view and keep tap the down button on the d-pad until you either fall through or it seems like you're jumping. If it seems like you're jumping, you've nearly got it, just got to figure out what you're doing wrong.

If you did it, congratulations. See, it's as easy as that. Happy glitching. ;).
