SubCargo Guides Hub
Every alpha walkthrough for submarine survival, delivery runs, and deep-sea loot in one place.
SubCargo is a Roblox alpha submarine survival game by DeltaCore Studio, inspired by Barotrauma. You and your crew pilot a sub through post-apocalyptic ocean veins, complete freight deliveries, dive into wrecks and labs, and keep hostile creatures away from the hull. The experience is built for co-op online play, and the developers recommend 2+ players per run. Game-breaking bugs can still appear during early access, so treat these guides as living references that we update as patches land.
This hub collects every SubCargo guide on the wiki. Whether you are loading into your first lobby or trying to stop Larry from chewing through the engine room, start here and branch into the topic that matches your question.
Start here if you are new
If you have never touched a ballast pump or flooded an airlock, read Getting Started first. It walks through joining a crew, understanding the bridge layout, and adopting a delivery-first mindset so your first alpha session ends with money in the bank instead of a flooded compartment.
From there, learn how to actually move the sub and interact with tools in Controls. Alpha builds sometimes remap binds between updates, but the core loop stays the same: one player steers, others manage systems, and everyone reacts when alarms fire.
Keep the submarine alive
Most failed runs in SubCargo trace back to neglected systems, not bad luck. Ballast and Systems explains neutral ballast values, pump wiring, reactor fuel, and power routing—the knowledge that stops your sub from nosediving the moment you throttle down.
When breaches, fires, or flooding appear, switch to Hull Repairs. That guide covers the welder, wrench, mop, fire extinguisher, and the habits that separate a patched hull from a total loss.
Explore, fight, and profit
Delivery pay keeps the lights on, but the seafloor pays for upgrades. Diving and Structures teaches the diving-suit loop: suit up at the airlock, flood the chamber, use your headlight in labs and wrecks, and sell loot back at dock shops.
The ocean is not empty. Larry—the community nickname for the Blood Worm—is the primary predator you will meet on many routes. Read Beat Larry for exact damage numbers, hull bite rates, and weapon choices before you waste ammo or expose the bridge.
Complete missions as a crew
SubCargo is a freight game at heart. Cargo Delivery breaks down accepting contracts, planning routes between dock stops, splitting roles, and cashing in without leaving cargo behind on the seafloor. Pair it with Crane Operations so dock freight actually lands in the hold before you shop.
Power and crew size decide whether those contracts survive. Reactor and Fuel covers dual rods, ReCore’s free rod, and the 20% flood shutdown rule. Smaller lobbies should read Solo and Duo Runs before stacking every duty on one headset.
Pair those mission tips with the Tier List when deciding which weapons and tools deserve your first paycheck, and bookmark Updates plus Patch Notes 0.2 for content drops that may change ballast behavior, APS pricing, or Larry’s spawn patterns overnight.
How to use these guides efficiently
Assign each player a lane before undocking. A common alpha crew splits into pilot, engineer, diver, and gunner, but smaller groups can double up—just never leave ballast and repairs entirely unowned. When something breaks, fix the leak before chasing loot; a ten-minute detour into a lab is worthless if the reactor room is already ankle-deep.
Cross-link habit: every guide below links to its siblings under this category. If you finish Ballast and Systems but still sink on idle throttle, Controls and Hull Repairs usually hold the missing detail. If deliveries feel slow, Diving and Structures plus Cargo Delivery together explain the earn-and-spend loop that funds better subs.

Frequently Asked Questions
Quick answers for SubCargo crews in Roblox alpha.
Which SubCargo guide should I read first?
Start with Getting Started for day-one crew basics, then Controls and Ballast and Systems before your first serious delivery run.
Are these guides accurate during alpha?
Yes, we base them on current alpha behavior, but DeltaCore Studio can change binds, loot, and creature stats between patches—check Updates after each release.
Can I solo SubCargo using these guides?
Yes—start with Solo and Duo Runs plus Reactor and Fuel. The game still recommends 2+ players because one person cannot steer, pump ballast, repair breaches, and dive simultaneously without risky delays.
Where do I learn to fight Larry the Blood Worm?
Read Beat Larry for stats, weapon counts, and survival positioning, then cross-check the Tier List for the best guns and explosives in the current meta.
How do guides connect to making money in SubCargo?
Cargo Delivery explains contract flow and dock stops, while Diving and Structures covers the loot-and-sell loop that funds welders, fuel, and better weapons between missions.
