30 Days on Cargo

30 Days on Cargo is a narrative survival horror game on Roblox set aboard a sinking cargo ship, developed by Brosyn Studio and launched in January 2026. Players explore flooded labs, manage their oxygen supply in deep sections, fight or evade a hostile crew, uncover hidden islands, and confront the Kraken lurking in the ship's depths. Since launch the game has reached nearly 3 million visits, driven by its atmospheric storytelling and a series of substantial post-launch content updates.

The ship is a layered environment - surface areas give way to progressively deeper flooded zones where oxygen management becomes critical. The crew that once worked the vessel has turned hostile, creating constant AI danger as you move through corridors searching for keys and supplies. A standout mechanic is the Key Fusion System: keys come in different colors and can be fused together to create new color combinations. Each fused key type unlocks a specific special container holding better rewards than standard loot - adding a crafting-puzzle layer on top of the survival loop:

• 🗺️ Ship exploration - layered environment from safe surface areas to oxygen-limited flooded depths
• ⚔️ Hostile crew - turned AI enemies patrolling corridors and labs throughout the ship
• 💎 Key Fusion System - combine colored keys to unlock special containers with improved loot
• 🏆 The Kraken - the boss entity lurking in deep sections; encountering it is a major milestone
• 🏠 Hidden islands - explorable areas beyond the main ship containing treasure and secrets

Gold is the primary currency, earned from looting containers and used for progression and equipment. The game features full voiced dialogue from NPC characters - including friendly coworker companions who provide story context and guidance - distinguishing it from most Roblox survival games. The badge data reveals the game's true difficulty: nearly 1.9 million players have joined, but only 447 have completed the full narrative.

30 Days on Cargo stands apart in Roblox survival horror through its story-first design, voice-acted NPCs, and a key-puzzle system that makes loot gathering feel purposeful. With regular content updates from Brosyn Studio, the ship continues to grow deeper.
