Find Submarine Upgrades at Ports
Looking for S.O.N.A.R. submarine upgrades? In Open World Survival, ports are the confirmed destination for unlocking ship improvements. Finding harbor outposts gives your crew somewhere to pursue upgrades and obtain supplies as you explore the ocean.
The developer's Open World Survival announcement connects that progression to two money-making activities: hunting enemy ships and recovering treasure. It establishes where upgrades fit into the mode without publishing a complete upgrade catalog or price list.
How Upgrades Fit Into Survival Progression
Open World Survival supports crews of one to six players. Its large map contains hazards, discoveries, and harbor outposts, so progression involves exploring rather than simply choosing a new loadout before every encounter.
A useful planning sequence is:
- Explore to locate a port.
- Check the ship upgrades and supplies available there.
- Fund your purchases through enemy-ship encounters and treasure recovery.
- Consider your crew's supply needs alongside the next ship improvement.
This is a planning outline based on the announced systems, not a specific sailing route. The announcement does not provide port coordinates, an interaction key, or the screens used to complete an upgrade purchase.
Earn Money Through Encounters and Treasure
The official survival overview names enemy hunting and lost-treasure recovery as ways to earn money. Both give your crew a reason to venture beyond a port, but the material does not establish which activity produces money faster.
Choose an objective your crew can handle and discuss the next port visit before leaving. Treat that as practical crew planning rather than a promised optimal farming strategy. There is no supported payout table, repeatable farming timer, or fastest-money comparison in the announcement.
Balance Ship Improvements With Crew Supplies
Harbor outposts also sell weapons, food, and medical resources. A port stop therefore serves more than the submarine's upgrade progression.
The publisher describes food, rest, and crew well-being as survival concerns. Neglect can leave the crew exhausted, seasick, or delirious. When discussing the next purchase, include those needs instead of treating every available resource as an upgrade budget.
The available material does not identify a universally best first upgrade. It also does not list individual upgrade effects or costs, so a named purchase order would go beyond what is documented.
