Independent developer Feldsparc today announced that Fathom Reach, an underwater roguelike deckbuilder, will launch on November 3, 2026 on Steam.
Before launch, players will be able to dive in during Steam Next Fest starting October 19, with an enhanced demo featuring the latest updates and refinements to the game.
Set beneath a ruined ocean, Fathom Reach combines turn-based deckbuilding, push-your-luck exploration, and player base raiding. Players descend through increasingly dangerous chambers, build powerful card combinations, and decide how far they are willing to push before bringing their loot safely home.
Chain the Perfect Dive
Fathom Reach is a single-player roguelike deckbuilder under a ruined ocean. Read enemy intents and choose your targets. Chain cards into explosive combos. Turn Armor into a crushing strike, fill a chamber with drones, or let corrosion finish the job.
Build a Deck That Breaks the Rules
Bring your loot home to craft and upgrade a deck from 220 cards across four factions. Build around heavy Armor, marked targets, corrosion, or drone swarms. Fit a dive module and discover a new way to make your favorite cards work together.
Build the Base You’d Hate to Raid
Give other divers a challenge of your own. Place gun-coral and traps, then choose the Pressure-Heart at your base’s core. Publish your defenses and they fight while you’re away. Read the defense reports, refine your layout, and take your deck into other players’ bases. These asynchronous player raids need the internet.
