The Heritage Gun is easily one of the most coveted legendary weapons in Deathloop—a brutal hybrid of the Rapier rifle and Strelak 50-50 shotgun, giving you unmatched power across both short and long ranges. This guide will walk you through every step required to claim the Heritage Gun and maximize its potential.

Why the Heritage Gun Stands Out

The Heritage Gun lets you toggle between a precise, long-range rifle and a high-powered shotgun. With the Duelist passive, every shot with one mode buffs the other and resets the reload—perfect for aggressive players who like fluid, reactive combat.

Where to Start

To begin the Heritage Gun quest, head to Karl’s Bay in the evening. Be warned: the streets are dense with Eternalists. A silenced Limp-10 or rare PT-6 Spiker will make traversal smoother. Once you exit the tunnel, make your way across the street toward Fathoms of Lament—one of Charlie Montague’s devious contraptions.

The Fathoms of Lament Puzzle

Inside, you’ll find a map with blinking lights—white and blue. Each represents a “present”—small challenges scattered throughout the district. Complete all of them to unlock the final puzzle inside.

Let’s break down the trickier ones.

Dawn of Reason – Code Puzzle

1. Head under the bridge near Fathoms of Lament.
2. Don’t use the front lever. Instead, double-jump or Shift into the side window.
3. Solve four environmental puzzles by lining up foreground and background images to reveal numbers.
4. Each number has a red hash mark indicating its position in a 4-digit code.
5. Combine your clues, jot down the code, and head outside.
6. Activate the front lever and enter the code to open the door.

Note: Codes are randomized per player. The example 5001 is unique to this run.

Inside you’ll find one of the required presents. Remember: they can explode, so always back away after activation.

The Hangars – Timed Platforming Puzzle

Hangar 1:

• Locate the present on the floor surrounded by tripwires.
• Disable them carefully and step back before interacting.

Hangar 2 – 30-Second Multi-Lever Challenge:

1. Start at the lever near the present.
2. Move across to the opposite wall and pull the next lever.
3. Drop to the lower level, cross back, and hit the corner lever.
4. Head to the far back opposite Harriet’s platform.
5. Jump up one level and activate the wall-mounted lever.
6. Climb onto the plane and pull the final lever.

Present unlocked.

Plane by the Docks

• Quietly take out Eternalists gathered around the fireworks.
• Claim the present near the plane’s nose.

Final Present Near Fathoms of Lament

• It’s one street away from the start.
• Go loud if you need to—clear the Eternalists.
• Interact with the final present.

The Final Challenge – Fathoms of Lament’s Lever Gauntlet

1. Head to the back-right room inside the building.
2. Disable the Nullifier field in the adjacent room using a grenade to destroy the battery.
3. Start the challenge via the initial lever.
4. You have 45 seconds to pull 7 levers upstairs in the correct order.

Pro Tip: Tripwires don’t explode, but they stop the timer. If triggered, run downstairs and restart the clock—levers reset.

Sequence:

• Lever 1: Start downstairs.
• Lever 2: Top level, straight back.
• Lever 3: Backtrack near the start.
• Lever 4: Opposite walkway.
• Lever 5: Drop down into the red room.
• Lever 6: Shift back up, drop again to side platform.
• Lever 7: Shift back up one last time.

Optimizing the Heritage Gun

We recommend these trinkets:

• Speedloader – Quicker reloads keep you reactive.
• Lightning Strike – Increased damage falloff range.
• Sure Shot – Improved accuracy and damage boost.

Combined, these make the Heritage Gun a deadly all-in-one weapon. You can pick enemies off from across the district or turn corners and annihilate them up close. The built-in Duelist passive (switch fire mode to buff the other and auto-reload) gives bonus damage and flow in chaotic fights.

If you prefer precision, the rifle mode is god-tier. If you like shredding Eternalists at close range, the shotgun dominates. Having both in one frees up inventory space.

Final Thoughts

Now that you’ve got it—go break the loop, visionary.
