I have tried a few times, but no luck. Reason is that the metal beam is so small so it makes it difficult to climb like that. Also you can't really grip the top of lighthouse at all so. I don't think it works
I love this game so I know a easier way to do it If you have a friend or something get them to get as high as they can while fly follow closely behind and once the get high up get them to flip upside down while holding on and then climb on them once you’ve climbed above them just jump onto the top of it and boom your done
And I thought that it was impossible, when you can upload videos, not necessarily tutorial tips or Easter eggs or funny and epic shorts, you could also upload gameplays like the one from when you escaped from the billboard
