SubCargo Crew Role Specialization
How to divide pilot, engineer, diver, and gunner work across 2–4 player alpha crews.
SubCargo’s Roblox alpha from DeltaCore Studio is a cooperative submarine delivery game—online co-op with 2+ players recommended on the official page. Roles are how crews translate that recommendation into wins instead of arguing mid-breach. This guide explains specialization for pilot/navigator, engineer/repairs, diver/loot, and gunner/security across two, three, and four player lineups, with links to checklists and mission guides so responsibilities stay clear between dock stops.
Roles in alpha are partly menu-driven (engineers may spawn with welders) and partly social contract. Write down who does what using the crew checklist every session.
Core roles at a glance
| Role | Owns | Typical spawn gear |
|---|---|---|
| Pilot / Navigator | Depth, routing, callouts | Varies by build |
| Engineer / Repairs | Welding, fires, systems | Often welder |
| Diver / Loot | Exterior scrap and objectives | Scrap collector (buy) |
| Gunner / Security | Larry and hostile DPS | Weapons from Krakken’s |
Captain-style leadership is optional—usually the pilot or most experienced player—but alpha crews benefit when one voice confirms checklist completion before undocking.
Four-player ideal lineup
Player 1 — Pilot/Nav: Drives the submarine, manages ballast where manual control exists, and calls Larry vectors. Reads delivery routes ahead of time.
Player 2 — Engineer: Stays hull-aware, welds breaches in ~11 seconds per section at full repair speed documented for alpha welders, and carries fire extinguisher for onboard blazes. Shops at Underforge for wrench and backup welder.
Player 3 — Diver: Equips scrap collector, exits on agreed timers, and recalls instantly on Larry callouts. Feeds economy for gun upgrades.
Player 4 — Gunner: Buys PPS, Gepard SMG, or APS from Krakken’s per tier list guidance; protects divers re-entering the hull.
Four players minimize role compression—ideal for learning alpha mechanics without burnout.
Three-player flexible lineup
Drop one slot by merging related duties:
Option A — Merge gunner into pilot: Strong aim pilots handle Larry while a dedicated engineer+diver pair repairs and loots. Best when the pilot has combat experience and calm callouts.
Option B — Merge diver into engineer: Engineer loots during calm legs and welds during fights. Pilot handles navigation; a dedicated gunner covers Larry. Best when exterior routes are short.
Never merge engineer away entirely—alpha without welds ends quickly when Larry chews starboard.
Two-player duo lineup
Official guidance still allows duo, but duties stack aggressively:
Player A — Pilot/Gunner: Navigates and shoots during encounters. Practices depth holds that keep SMG fire on Larry when he surfaces.
Player B — Engineer/Diver: Welds by default; exits for scrap only when Player A confirms stable autopilot or parked sub.
Run the crew checklist duo merge section verbatim. Both players leaving the hull is a voluntary wipe in most seeds.
Role synergy during Larry fights
Larry’s documented 300 HP and hull damage bursts demand coordinated roles—see Larry stats for numbers.
- Pilot calls contact early.
- Gunner focuses DPS; friendly fire hurts teammates in alpha.
- Engineer prepares to weld immediately after disengage.
- Diver aborts exterior work.
Post-fight, engineer repairs before shopping—dock shops can wait if water is still rising.
Role synergy during calm delivery legs
- Pilot optimizes fuel—grab free ReCore rods each dock.
- Diver farms scrap for credit surplus.
- Engineer pre-welds stress sections near prior breach points.
- Gunner inventories ammo and plans Krakken purchases before the next hot zone.
Calm legs are preparation, not AFK time. Alpha bugs like ballast glitches appear without warning—use quiet minutes to verify systems.
Shopping responsibilities by role
Split credits transparently:
- Engineer budget: welder backup ($230), extinguisher, wrench.
- Gunner budget: pistol ($750) → SMG ($1,150) → APS ($2,120) progression.
- Pilot budget: extra fuel rods ($320 each) when routes exceed ~8 minutes per rod.
- Diver budget: scrap collector once combat minimums met.
Full prices and priorities live on the dock shops page. Avoid duplicate welder purchases unless you want redundancy against tool loss.
Communication norms that save runs
Short callouts beat long stories:
- “Breaching port midship”
- “Larry surface aft”
- “Diver returning, hold depth”
- “One rod left”
Link getting started for control basics before enforcing callout discipline.
Role selection and alpha changes
SubCargo alpha can alter spawn loadouts, role names, or captain perks between builds. Treat menu choices as starting gear hints, not permanent MMO classes. Reassign duties in lobby when a friend prefers gunner over engineer.

When specialization fails
Roles break down when:
- Nobody claims fuel duty and the sub dies mid-ocean.
- Gunner shops alone while hull sits at 30% integrity.
- Pilot dives during diver exterior work without callouts.
- Crew ignores alpha bug reports and repeats the same ballast failure.
Reset with the checklist, not blame. Early-access means systems fail too.

Frequently Asked Questions
Quick answers for SubCargo crews in Roblox alpha.
What is the best role for beginners?
Engineer teaches hull awareness and win conditions—welding saves runs. Gunner is second if the player already understands shooters.
Can one player fill every role in duo?
Only by merging pilot/gunner and engineer/diver. True solo role coverage is not viable when both players leave the submarine.
Does captain role matter in alpha?
Captain is often a social lead, not a hard buff. Use it to designate who reads the checklist and confirms fuel before undocking.
Which role buys fuel rods?
Usually the pilot or whoever manages route timing, but any role can purchase at ReCore—just confirm collection in voice chat.
How do roles connect to the delivery guide?
Delivery pacing tells each role when to prioritize cargo versus scrap, and when to skip shops for timer safety.
