Mass Effect 3. The docking bay on the citadel. I was walked into the keeper that wanders about and was pushed over the barrier and just fell in to oblivion. After a couple of minutes i restarted. Now I avoid that keeper like the plague!
In Fallout 3 I went into the power station and when i went out the back towards all the solar panels lots of weird gray columns appeared to crash around me. And some strange crashing sound effects played. They stayed there for ages, in after exiting and re-entering the area.
