My vote goes for Tomb Raider II and the floating islands levels. The game is a relativity normal globe trotting affair for Lara until she gets transported into the fucking shadow realm here. This level gave me major scares as a kid since you’re traversing a giant void being chased by animated statue warriors out to kill you.

Metroid: Fusion, before you’ve regained your power and just have to run from the X… same feeling with the EMMIs in Dread.
