Your mission is to seek out every one of these boxes and open them. Each of those lights indicates a “present”, a ticking cardboard box with a light on the top. Look closely at the map, and you will see lights in a triangular shape marking places around the area. Inside, you'll see a large gun in a tube and a map of Karl’s Bay. Head to the Fathoms of Lament building, near the center of the region. However, you'll need to complete several puzzles first, and I've laid their solutions out below.

The TL DR is that the Heritage Gun is found in the evening Karl’s Bay.


To get the Heritage Gun in Deathloop, you have to be clever, agile, and one step ahead of your enemies.
