About this game

NEW! Ascension Mode

Fast, Intense, and Competitive. Discover pure combat runs! You start with a generous inventory featuring guaranteed rare tiles. Shortened animations, tight timings, intense music. No dilemmas, no detours - dive into rhythmic battles with enticing rewards. Climb the global leaderboard, challenge your friends, face escalating difficulty and aim for the perfect score.

You are not the hero. You are the monster. Unbound Eternity is a deck-builder with turn-based combat where you invade the lands of the "Eye" cult. Master your characters and their rune combos, craft your deck, and forge your path.

Story Mode: Unlock & Conquer Discover characters, powers, and secrets. Navigate between battles, merchants, and twisted dilemmas. Collect permanent buffs and artifacts to challenge the cult's hero.

Runes Are Your Engine Spend runes to play cards. Chain tiles, poison enemies, sacrifice health for devastating attacks. Each monster has multiple runes per turn - use them for brutal combos.

Created by an Indie Duo Solid mechanics, replayability, and dark humor. 2 to 8+ hours per Story run - or endless hours in Ascension. All the cards are in your hand.

So, are you ready?
