Sadly, CEA doesn't have Theater. I'll try to explain the best I can. Check this thread's parent board's title if you came directly from the "Unread Posts" and don't get what I'm talking about.
In
this room there's a window. If you look through it on New Graphics Mode you can see a polygon floating in the chasm on the other side of the window.
If you go to the chasm, where a small cutscene of the MC kicking a grunt's breathing mask occurs, you can see it too.
You can't see it in Old Graphics Mode, but maybe it's because it's too dark.
It's either a bug or a platform that's been there for 10 years without being found.
Thoughts?
