Moonsigil Atlas

Moonsigil Atlas is a roguelite deckbuilder where you place cards, called sigils, on a grid to fight astral entities. There are no energy or action-point limits on how many cards you can play; you can play as many as fit. Each sigil has its own shape, keywords and effects, making combat a tactical challenge of arranging cards and building synergies.

Position your sigils

Rune placement, adjacency, overlap and persistent effects can combine to create powerful interactions. Place sigils at the right time to trigger combos. You can also build around drawing cards: for example, draw an unlimited number to deal unlimited damage, or make ten copies of your strongest card.

Modify your deck

The upgrade system is fully modular and player-driven. You can reshape cards, inscribe runes, add keywords and make other modifications. Spread upgrades across your deck or concentrate them on a few cards; tens of thousands of possible combinations let even simple cards become central to a build.

Runs and encounters

Choose from three characters with radically different playstyles, alternate starting decks and a fully randomized map. Runs can also include unlockables and forbidden cards, alongside more than 250 cards in total.

You face dozens of astral entities and three Titans, which reshape the board. Hostile zones, shifting grids and unique win conditions make each encounter require adaptation.
