From itch.io: Armour Astir: Advent is a high-fantasy roleplaying game about striking back against an authority that seeks to control you. It is a game of rival pilots clashing in steel-clad Astirs, of soldiers holding their own against the odds, and of spies and diplomats twisting the world to their ends. It is not a game of careful preparation or pleasant truces; It's hard to change the world without taking a risk.
