I noticed today, while playing with Tidal, that if I go to the top of the map and fall all the way down in Spartan form, the fall takes away full shields and 2/3 health. Excited, I took a stock Fusion Coil [UNSC] and dropped it from the same height, but it didn't explode. I'm done messing around with Forge for tonight, but does anyone think there might be a way to get exploding objects to explode from fall damage now?
Fall damage has been there. You just have to faaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaall. As far as I know, explosive objects still don't take fall damage, unfortunately.
Like storm said, fall damage was always there but the heights needed to encounter are so large that you rarely encounter them.
