So, I was messing around in forge on Stasis when I noticed this little easter egg. There is really nothing to special about it, at least I don't think so. It happens around 4 minutes into a game. I'm curious to see if 343i included any other easter eggs on this map.
Im not going to be "that guy" but it looks like they used the Halo 5 forge to create the crumbling, Its funny, when they script they don't get rubberband object movement/rotation.
This is more like a dynamic backdrop like the Pelicans on Empire or the Hornets on Skyline rather than an Easter egg. But very good nonetheless. 343 has always been good at these things.
Unfortunately I don't believe you can. I'm pretty good at getting past boundaries and I haven't been able to get there.
