October Rust is a game about the last stand. "A game of personal fall for the greater stand", as slogan says. Intended for 3-5 people, including one game master.
It's about one-shot heist in goal to try the answer the Final Question of the adventure, in attempt to fix the world or at least alter it. And the world is ungrateful, as early modern fantasy (with some grim and gothic themes) can be. Fallen characters in the world, which went down. Or at least, the protagonist are bastards, but the society is even worse...
October Rust also invokes the grim atmosphere of everlasting rain. And it can only go worse - the weather will escalate, the thunderstom will arrive.
It's done by improvising the adventure (answering five questions of Adventure List, then trying to play it's contents). Then, the game itself will force you to make hard choices about resources you'll spend: either you will need to sacrifice your precious belongings ("trappings"), deny your background or spent your rust points. The latter brings you closer to confessing your Sin from the past. If you don't spend those resources during conflict, you will roll some dice and add months to Doom Clocks (starting in May). When Doom Clock hits December, you perish!
