Armour Astir: Advent
A Powered By The Apocalypse game about giant magical robots and the people that control them.
Armour Astir is a high-fantasy role-playing game about rebellious magicians, fighters, clerics, and forty-foot tall magical constructs, caught up in the struggle against an Authority that seeks to control them. Inspired by Mobile Suit Gundam, Escaflowne, and others, the stars of Armour Astir are young, talented, and at the forefront of violent revolution. Evening the odds against their foe are Astirs; immense suits of magic-fueled armour - the smallest of which still tower above regular men - that are piloted by talented individuals known as Channelers.
Right now, all the core moves, playbooks, and downtime moves are implemented, as well as examples of equipment, enemies, and mech stat blocks, and temporary (but form-fillable) character sheets. GM Principles, Agenda and Moves are also available, as well as a brief glossary and list of shorthands - in short, aside from longer-term features like factions, the game is available for testing! There's also a quickstart/testing pdf available with a condensed version of the rules, as well as a feedback form, linked in the above document.
