Tags: you're the monster
Monster Force Terra is a light storygame using the Apocalypse World Engine to tales of giant monsters who terrorize the Earth but also just happen to save the human race from an even worse threat in the process!
You take on the roles of the kaiju in this game, going about your own business of seeking food, shelter and a mate, when disaster strikes! In getting back to the normal order of your lives, you inadvertently find yourselves becoming the heroes, though you may never be aware of what you’ve done. Play your monster as a pawn in the story, using them to achieve the goals that you want, by using them to stomp, steal or investigate the story’s obstacles.
