Abyssus Lobby Secrets Guide

Aug 16

The lobby in Abyssus looks like a simple staging area at first, but it hides multiple secrets that can unlock new weapons and rewards. From a hidden fountain behind a waterfall to a scoped weapon tucked away on a secret path, the lobby is more than just a safe hub.

The main lobby secrets in Abyssus are the Secret Pond fountain, the Scoped Weapon path, the Logbook, and the Cabinet of Curiosities.

Secret Pond and Aquatic Weapon

Behind the waterfall in the lobby is a hidden room with a fountain/secret pond. The wall symbol matches the cube you earn for completing challenges, hinting at its importance.

The fountain has three busts: a frog, a skeleton, and a snake. These correspond to three elite minibosses found in Act 4 Stage 1. Only one elite spawns per run, so you need multiple runs or a modifier that forces all three in one go.

When all three elites are defeated, their statues begin spewing water. Once active, a fish appears in the fountain. Picking it up unlocks the Aquatic Weapon, also known as the Fish Deity or Fish Gun, for future runs.

Scoped Weapon Path

Another hidden reward in the lobby is the Scoped Weapon. To unlock it, you must reach the end of the lobby’s secret path. The Logbook describes it directly: “Find the scoped weapon by reaching the end of the Lobby’s secret path.”

This makes exploring every corner of the lobby worthwhile, since new routes can open up after progression milestones.

The Logbook

The Artefact Room in the lobby contains the Logbook, one of the most important interactable objects. It tracks:

Challenges
Relics
Expedition history
Player and enemy stats

The Logbook confirms unlock conditions, such as which weapon or ability comes from which event. It is the best way to track long-term progress and missed rewards.

Cabinet of Curiosities

The lobby also hides the Cabinet of Curiosities, an unlock tied to gathering every artifact. Completing it rewards Soul Fragments, which are vital for upgrades.

Lobby Fissures

Surge Fissures appear in multiple areas, including the lobby. Destroying them is part of larger challenge lines that reward unique cosmetics and resources.

Final Blurb

The Abyssus lobby is far more than a waiting room. From the Secret Pond that unlocks the Aquatic Weapon to the Scoped Weapon path, the Logbook, and the Cabinet of Curiosities, it serves as a hub of hidden progression.

Explore every corner and track your unlocks, because the lobby holds the keys to some of the most unique rewards in the game.
