Armour Astir: Advent is a high-fantasy tabletop role-playing game that places players in a world where magical mecha are real, the world is at war, and the players are seeking to strike back at a force that wants to control them. Players may take the role of Astir mecha pilots or take support roles that shine off the battlefield. Based on the Powered by the Apocalypse framework, combat is heavily narrative driven and action-packed, focusing on forcing players (and their rivals) to take risks and face the consequences of their actions.

Depending on the players and world, games of Amour Astir: Advent may feel more like Mobile Suit Gundam, Escaflowne, or Pacific Rim.


We run official modules, “homebrew” content, and material from our Published Works. In order to maintain novelty and prevent any temptation to engage in metagaming, we do incorporate modifications and changes into plot details for each performance while maintaining the original spirit and overarching story. Additionally, players interactions actively shape the world and plot of each story as it unfolds. As such, no two performances are exactly the same. Don’t see what you’re looking for?
