Investigation system
As an operative of the Northern Commandery, the protagonist does not just fight and sneak. He investigates. The game includes detective mechanics where the player gathers evidence, interrogates suspects, and uses deductive reasoning to solve cases.
Core mechanics
Interrogation Questioning suspects and witnesses. How conversations are handled affects information gathered and can open or close branches in the investigation.
Observation Examining environments and crime scenes for physical evidence. The demo included a study/archive room (书房) with destructible account ledgers and scattered documents that could be examined during combat.
Deductive reasoning Piecing together evidence to identify culprits and uncover connections between events.
Precognition Using the protagonist's abilities to foresee possible outcomes, tying into the Heavenly Deduction system.
Heavenly Deduction synergy
The Heavenly Deduction system creates unique dynamics with investigation. If one line of questioning reaches a dead end, the player can rewind and try a different approach while retaining knowledge from the first attempt. A suspect who reveals partial information in one timeline can be questioned differently in the next, using information they should not know yet. This makes investigation a process of accumulating knowledge across timelines rather than finding the single correct path.
Mission integration
Investigation provides alternative mission completion methods. A mission solvable through combat might also be resolved by finding the right evidence, identifying the real culprit, or leveraging information to avoid a fight.
