Enter the Gungeon is celebrated for its deep lore and layers of hidden content that keep players returning for multiple runs. Among its most elusive destinations is the Abbey of the True Gun, a secret second floor that tests both player patience and mechanical skill. Unlocking this sanctuary requires navigating a precise set of steps across multiple chambers without taking damage.

How to Locate the Altar and Access the Abbey

To begin your descent into this hidden floor, you must first visit the Oubliette, which serves as the game's first secret area. Deep within its halls, you will find a special piece of armor known as the Old Crest waiting on a pedestal. Grabbing this item is only the initial step, as its fragile nature introduces the run's true challenge.

Once acquired, you must carry the Old Crest safely into the Gungeon Proper without taking a single hit of damage. If an enemy manages to strike you, the crest will instantly shatter and lock you out of the secret level for that run. Successful players must then find a unique room containing seven massive bullet statues and place the intact crest onto the central altar to reveal a hidden staircase.

Secrets of Brother Albern and Floor Loot

The rewards for enduring this stressful journey are incredibly substantial, offering a significant boost to your overall resource pool. The Abbey of the True Gun features an entirely separate set of room layouts filled with valuable chests and helpful item drops. This extra level allows dedicated players to accumulate vast amounts of currency and powerful weaponry ahead of the later chambers.

Additionally, the floor guarantees a meeting with a special non-player character named Brother Albern who resides in a hidden room. Finding his secret corridor allows you to interact with him and claim a dedicated chest containing unique items. Because of how the map generates, this floor frequently spawns multiple hidden rooms, giving observant players an unmatched tactical advantage.

Conquering the Fearsome Old King Boss Fight

The journey through the Abbey culminates in an unforgettable showdown against the Old King, an aggressive variant of the first floor's Bullet King. This ancient ruler possesses an immense health pool and utilizes incredibly dense bullet hell patterns that can easily end a promising run. He frequently introduces jammed bullet formations that deal massive damage if you fail to dodge properly.

Defeating this challenging boss requires excellent positioning and patience as you chip away at his health bar over a prolonged encounter. Upon his definitive defeat, you are rewarded with high-tier gun synergies and rare items that make subsequent floors far more manageable. Overcoming this trial successfully positions any player to comfortably conquer the deepest depths of the Gungeon.
