This Dead Space remake could also be termed a narrative one, since while it doesn't change the major story beats or plot of the original it does cast them in a completely new light via side quests, holographics logs, new characters, and through Isaac being able to speak this time. People like Elizabeth Cross, who you never interacted with directly, are now fully-fledged characters who have their own individual plotlines. The side quests also offer Nicole's perspective on what was happening onboard the Ishimura, and give you more insight into the cruelties of main antagonist, Dr. Mercer, who's now a more fully-developed character.
