I was screwing around in the Beta the other day and right after you kill that first Minotaur and hack the Vex Conflux to make the floating platforms spawn, there's a way to get stuck inside the actual platforms. If you jump prematurely in the space where the floating platforms will spawn, you'll get stuck inside the platform with no way out. I believe I took a video clip of this, but I can't provide it at this time. I'll update this post with the video clip when I can get a hold of it.
