Visibility is part of this task
Assassin Killer explicitly describes using surroundings and shadows to avoid flashlights while approaching targets. Before an action, identify which part of the route is currently illuminated and where the character would be afterward. A short approach is not necessarily a concealed approach. The useful question concerns what the visible light covers, not just how close the target appears.
Plan the departure as well
The description also asks players to escape without being spotted. That makes the position after an encounter relevant before initiating it. Look for the route the current scene actually allows, without assuming a vent, hiding place or automatic escape action. The source's corner warning supplies a reason to inspect the next opening, but does not establish a fixed patrol route or a predictable flashlight cycle.
Keep this a game-reading exercise
The control field says tap to kill, which does not fully explain movement or targeting. Read the running game's instructions before interpreting a tap as a particular path. For a focused attempt, compare the area you expected to remain hidden with what the game actually shows. This note gives no real-world violence advice or tested stealth route; it connects the fictional task's stated light and escape conditions with a clearer on-screen decision.
Make the stated concealment objective part of the approach.
