Across the Obelisk Sands of Ulminin extends the cooperative deck-building roguelite with additional content, bringing new cards, characters, and challenges to its card-based fantasy adventure.

Players continue building synergistic decks across cooperative runs, adapting to fresh content layered onto the core experience. It suits existing fans of the game looking for more of its card-driven roguelite gameplay. It doesn't try to be everything at once, instead concentrating on doing its central idea well across a compact, digestible package.
