Fathom Reach
Feldsparc
An underwater roguelike deckbuilder where every dive is a gamble. Chain explosive card combos, push deeper for richer loot, and surface before your hull breaks. Bring the haul home to upgrade your deck and build a base other players can raid while you're away.
Overview
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.
KNOW WHEN TO SURFACE
Your hull carries every hit into the next fight. In Endless Descent, each breached Pressure-Heart offers a choice: bank your haul or descend into tougher chambers for richer loot. How much can you risk bringing home? Solo dives also include Open Descent and the shared Daily Signal. All three play offline.
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.
