I had one of these a few nights ago, on the dark side of a planet. The atmosphere as I progressed through the abandoned base, cutting panels and forcing doors open, was amazing. Like walking through the set of an Alien movie. Even though intellectually I know FD have neither the resources nor the inclination to program jump-scares into ED (this isn't Alien or Doom), there was a palpable tension as I moved through the facility using only the flashlight, and a sense of physical relief when I finally got the reactor working and the lights started coming back on. And all despite the only real danger being running out of energy cells before the suit recharge sockets became active.
For its many flaws, immersing the player in atmospheric scenarios is one of the things ED is very very good at given the chance. The visual design, the audio landscape and the sheer sense of isolation can occasionally combine to produce something very special.
No doubt given enough time we will all learn the limited range of layouts of these powered-down facilities and be doing blasé speed-runs through them as a matter of routine, idly "grinding" credits and "farming" materials from the lockers. But for now at least they represent another set of circumstances in which all the good things about ED's presentation mesh together wonderfully. Enjoy them while they're novel.
