History of Heart Room

The Heart Room is a sub-room of the first encounter arena in the Vesper's Host dungeon. It does not lead into space, and it holds the first puzzle of the armor-focusing series for the Rogue Network quest.

Overview

After clearing the first encounter, enter the room and find an Operator buff. Go down the stairs and look behind you to see red and blue number panels. The blue panels show a two-digit target, and you must shoot four different red panels whose values add up to that target.

The room returns with later puzzles in some guides. Guides disagree on those later mechanics, so check a current walkthrough.
