Abyss is a deep-sea exploration game on Roblox that combines progression-based combat, exploration, and survival mechanics. As players descend into dangerous biomes, upgrading guns and tubes becomes essential for survival. Each gun offers increased damage, range, or utility, while tubes determine how deep you can safely travel.
This guide covers every gun and tube in Roblox Abyss, explaining how to unlock them, where to buy them, required quests, depth requirements, and progression tips. Whether you are a new player or pushing into late-game biomes, this article will help you plan your upgrades efficiently.
Understanding Guns and Tubes in Roblox Abyss
Before diving into the full progression list, it is important to understand the roles of guns and tubes.
Guns
Guns are your primary tools for combat and interaction with hostile creatures. As you progress deeper, enemies gain more health and aggression, making early guns ineffective.
Tubes
Tubes act as your mobility and survival equipment. Each tube has:
- A maximum depth limit
- Oxygen capacity
- Durability for deep-sea pressure
Progression in Abyss is not possible without upgrading both guns and tubes together.
Starter Guns in the Forgotten Deep
The Forgotten Deep is the starting biome where all players begin their journey.
Bottle Gun

- How to get: Automatically granted when you join the game for the first time
- Cost: Free
- Use case: Very early combat and basic interactions
This gun is quickly outclassed, but it helps players understand shooting mechanics.
Guns Sold by Henry (Starter Biome)
Henry runs the harpoon gun shop in the Forgotten Deep. These guns form the early progression path.

- Starter Gun: $75
- Beginner Gun: $350
- Advanced Gun: $1,150
- Air Rifle: $2,150
Each upgrade improves damage and reliability, making exploration safer in early biomes.
Mid-Game Guns in Ancient Sands
Ancient Sands introduces pressure mechanics, meaning you cannot enter with weak tubes.
Crossbow Gun
- Location: Ancient Sands
- Cost: $4,750
- Requirement: Tube capable of handling deeper pressure
This gun offers improved accuracy and damage, making it ideal for mid-game enemies.
Wasted Gun

Ancient Sands is often where players struggle, so upgrading both gun and tube is critical.

Progression Tips for New and Returning Players
- Always upgrade your tube before attempting deeper biomes
- Do not rush Ancient Sands without proper pressure resistance
- Quest guns often unlock entire shops or areas
- Save money for late-game upgrades instead of over-investing early
- Oxygen pods can help in emergencies, but should not replace tube upgrades
Final Thoughts
Roblox Abyss rewards patience, planning, and exploration. Guns alone will not carry you through the depths, and tubes without proper firepower will leave you vulnerable. Following a structured progression path ensures smoother gameplay and fewer frustrating deaths.
By understanding where to invest your money and time, you can efficiently unlock every gun and tube and experience everything Abyss has to offer.
