For the rule to apply, there need to be at least 2 harder difficulties above normal (Normal/Hard/Hardest applies, Easy/Normal/Hard does not), and the hardest difficulty needs to not be unlockable, or playable through some type of NG+. There are exceptions, such as Doom 2016, Doom Eternal, Halo (except 2), Quake 1, STALKER (hardest difficulty reduces the health of all humans), or Starcraft. System Shock Remake is available now for the PC.This is a rule I usually abide by for western games. With this in mind, the System Shock Remake has the potential to last up to 40 to 50 hours for completists. Moreover, achievement collectors must play the game at least twice with a guide to unlock everything. This is alleviated somewhat by the achievements, but only because it shows how much there is to find and discover at the Citadel Station. It is designed so players can take their time and mentally digest everything the sci-fi horror offers. System Shock is an immersive game, and part of the immersion is dropping the player into its world without handholding.

Learning the Citadel - which plays like a science fiction dungeon - will take time, so the most determined players must know the map like the back of their hands. However, it will take several playthroughs and practice to become good enough to pull this off.

As mentioned above, the highest challenge expects players to finish the game in 5 hours or less. With an average of 25 hours to finish a normal playthrough of the System Shock Remake, collectors and completists will take much longer to complete the game.
