The gates are officially open for visitors. A free demo of Sealbound: Cthulhu Rising is now live on Steam — two gates (Miskatonic Academy and Seoul), two heroes (Carter and Neo), and the full combo-building card battle loop, yours to break.
Play the demo on Steam — and if the numbers get big enough, the wishlist button is right there.
What shipped this cycle
The Mythos Codex
The bestiary is open. All 16 bosses now have Codex entries with lore in both English and Korean — each one unlocks as you actually encounter it in the world, and past sightings are backfilled to your collection. The card grimoire tracks flavor text the same way. If you like knowing exactly which Outer God is about to ruin your evening, this screen is for you.
The Five Seals campaign
The world map has a spine now. Five themed gates — the Academy, Seoul, Egypt, the Arctic, and England — each guard a seal, and the fifth seal opens the way to R'lyeh itself. Weaken the seals before the raid and the final fight gets meaningfully easier. The campaign opens with a Miskatonic prologue and closes with proper seal endings.
Bosses that fight back in phases
Boss battles now swap their backdrop as the fight escalates — every boss phase has bespoke top-down art, and telegraph lines warn you (in your language) about what's coming. Combined with the immunity-puzzle design of the Mythos bosses, each fight reads less like a damage race and more like a lock you're picking mid-combat.
A hundred small cruelties removed
- Heroes found their voices — 77 battle barks and lobby greetings, fully localized.
- Every city rolls its own board layout now, with route planning that actually rewards reading the tiles.
- AI opponents got sharper heuristics, and piercing damage got real teeth.
What's next
The road to Early Access continues: deeper effect engines under the hood, more of the world map coming online, and the next content drop is already on the workbench. Wishlist, play the demo, and tell us which boss broke you first.
