Terminal roguelikes have carved out a devoted niche by trading polish for mechanical depth, but few have dared to combine naval commerce, broadside combat, and crew management into a single coherent turn-based loop. Caribbean Prospector, a new free roguelike from developer at10ti0n, attempts exactly that, transplanting the open-ended captaincy framework of Magellan’s Prospector from space to the golden age of Caribbean piracy.
Introducing the game on Reddit, the developer explains the game frames itself around three core systems that feed into each other. You trade between ports where merchant convoy arrivals move prices dynamically, accept quests for coin and reputation, and engage in broadside battles that escalate into close-quarters combat on a top-down deck map. When you grapple an enemy ship, your actual crew physically crosses the planks with you, and killing the captain forces the remaining crew to surrender.
Captured vessels can be conscripted into your fleet under officers you command. Ashore, you forage, mine, dig for treasure, and catalogue wildlife for the Royal Society, creating a rhythm that bounces between sea and land without feeling ancillary.
The design includes five distinct careers, three difficulty tiers with an Ironman option, and seeded world generation to support both one-off runs and repeatable exploration. Caribbean Prospector runs in any terminal and launches in its own window through Steam, with full controller and Steam Deck support built in from the start.
The developer disclosed upfront that substantial portions of the codebase were written with Claude AI assistance, though design, playtesting, and all screenshots reflect human authorship.
Caribbean Prospector is available free on itch.io for Linux, Windows, and Mac. Whether this mix of trade sim, tactics, and roguelike progression pays out depends largely on how well those systems integrate under pressure.
