The bounty of ventilation shafts should clue you in to Shadows Of Doubt’s immersive-sim credentials. In particular, the Deus Ex lineage: there are sticky notes with password reminders, emails to read, and some of the most lovingly-presented locked doors we’ve ever bumped up against. You can knock, try the handle, or move your cursor down to peer through the crack at the bottom. Each handle has a lock percentage, indicating how hard it is to pick, and a strength value in case you decide to apply a shoulder to it. And some doors are sealed with keycodes – though we fail to find a single one that opens to ‘0451’. These procgen algorithms, they’ve got no respect for the classics.
