About Moonsigil Atlas
Moonsigil Atlas is a roguelike deckbuilder developed by Snake Tower Games and published by Twin Sails Interactive. It launched on Steam for Windows and Linux on 28 May 2026.
Instead of energy or mana, every card is a sigil with its own shape that you place on a grid, so you can play as many cards as fit. Adjacency, overlap, runes and persistent effects drive combos, while a modular upgrade system lets you reshape cards, inscribe runes and add keywords. With more than 250 cards, three characters with very different playstyles, a randomized map and cosmic bosses including three Titans that reshape the board, every run invites new game-breaking builds.
