SubCargo Diving Suits, Airlocks, and Seafloor Structures

Deliveries pay the bills in SubCargo, but structures on the seafloor pay for upgrades. DeltaCore Studio’s Roblox alpha scatters procedurally spawned sites—labs, wrecked submarines, drilling platforms, and other points of interest—through ocean veins. Each can harbor tools, sellable loot, and rare items like Data Chips in current milestones. Reaching them requires a disciplined diving suit and airlock routine, good headlight habits, and a crew that keeps the sub alive while you are outside. This guide walks the full loop from suit-up to dock-side selling.

Before you flood the airlock

Exterior ops fail when interior crews multitask poorly. Brief your team:

• Pilot holds position or slow orbit so the airlock hatch faces safe approach angles.
• Engineer compensates ballast before and after flooding—see Ballast and Systems—so the sub does not keel into rocks while you exit.
• Interior buddy watches doors so no one opens the wrong hatch into a flooding compartment.

Locate the diving suit spawn near the airlock before emergencies. Alpha subs place lockers differently; walk the route once at dock. Confirm you have oxygen or suit duration UI visible; returning with seconds left is a common rookie flex that ends in corpse loot for Larry.

Step-by-step airlock flood and exit

1. Equip the diving suit via locker or inventory prompt.
2. Seal interior doors leading to sensitive rooms (reactor, bridge) so accidental floods stay localized.
3. Enter the airlock inner bay and close the interior hatch behind you.
4. Activate the flood valve; wait for chamber water level to equalize with outside pressure.
5. Open the outer hatch, exit, and toggle headlight immediately—dark structures hide walls and predators.
6. Communicate distance and oxygen timer on voice chat.

Return by reversing: outer hatch closed, drain the chamber, remove suit, store tools, report loot weights to engineering for ballast tweaks.

Structure types and loot expectations

Labs appear frequently in community farming routes and often stock diverse items—electronics, tools, consumables—minus a few rare exclusions like broken TVs in some alpha versions. They are ideal for crews learning loot pacing.

Wrecked submarines spawn less often but can carry expensive salvage in smaller quantities. Send experienced divers with spare oxygen and a clear tug-back timer.

Drilling sites are rarer landmarks with industrial flavor loot; scout carefully because terrain around drill rigs loves to snag hulls if the pilot drifts.

Additional alpha POIs may appear as updates land—watch Updates for new structure tables. Random generation means not every site holds jackpot loot; budget time against active cargo deliveries in Cargo Delivery so you do not miss contract timers.

Headlights, navigation, and hazard awareness

Toggle headlight as soon as you exit. Interiors use heavy fog and contrast tricks; without light you will miss exit doors and walk into Larry ambush zones. Mark your airlock vector mentally—bubble trails, tether lines, or compass UI if enabled.

Surface predators matter. Larry—the Blood Worm—patrols open water and sometimes surfaces near structures. Divers should stay aware of shadow movement; gunners aboard should track exterior cameras. If Larry attaches, abort loot and prioritize Beat Larry responses—hull damage continues while you hunt scrap.

Tools you will find and why they matter

Structures commonly drop or stock welders, wrenches, mops, paint guns, oxygen tanks, and flares. Even if your sub spawned with basics, duplicates let flex players repair without running half the hull length during breaches—see Hull Repairs.

Data Chips and similar exclusives tie into progression and sell values in alpha 0.2.x lines; treat them as priority grab items when identified.

Loot and sell loop at docks

Successful dives end at dock shops, not inside the structure. Sell scrap and high-value items at vendor counters, bank cash for fuel and welders, and reinvest before the next vein push. Pair selling with contract turn-ins so one dock stop clears cargo and inventory clutter together.

Underforge pricing examples from community wiki data: a welder costs around $230 if you prefer buying over looting—compare with time spent diving versus delivery payouts on your route.

Use the Tier List to decide whether new weapons beat another diving run for DPS upgrades against Larry.

Crew roles during exterior ops

Diver: loot focus, timer calls, flares for interior rooms.

Spotter/gunner: watches exterior feeds, fires if Larry approaches.

Engineer: ballast compensation, ready to drain airlock fast on emergency recall.

Pilot: holds sub position, prepares emergency ascent if diver pings distress.

Solo divers in alpha are possible but violate the game’s 2+ player recommendation—always assume someone must stay inside to prevent ghost subs from drifting into walls.

Common mistakes and fixes

• Flooding without suit: instant casualty; reset at dock and retrain sequence.
• Leaving inner hatch open: floods reactor; enforce door checklist.
• Overlong dives: suit oxygen depletes; set hard return timers.
• Ignoring weight: heavy loot sinks subs on return; engineer drains ballast proactively.
• Loot greed during breaches: interior flooding kills missions; recall when Hull Repairs calls fire.

Planning structure detours on delivery routes

Accept contracts first so detours have deadlines. Pick structures along vector, not opposite the next dock. Communicate ETA slippage if cargo timers exist in your alpha build. One lab en route beats three out-of-the-way wrecks that expire your freight.

SubCargo early access will add caves, crab sites, and new POIs over time—this guide’s principles (airlock discipline, headlight on, sell at dock) survive even when spawn tables change. Report broken airlock prompts or empty structures in-game and cross-check Official Links for developer channels.
