They made quite a few changes, but they were mostly in directing you towards a certain route. In the end, it actually was easier this way. Though, I can't be the only one that noticed that it's the same as the dark mission in the normal playthrough. The only difference is you 'destroy' them, instead of 'activate' them, but oddly, you shoot them both times. Lol. I do not own any content within, it is strictly game-play footage.
