As time goes on, more characters will join the colony. The characters have a randomly generated set of traits which affect how they can contribute to the colony, the decisions they make, and how their existence affects the other characters. The player characters (referred to as "pawns" in game documentation) are stranded on a procedurally generated planet located in the frontiers of known space (a "rim world"). The biomes have been tweaked so they don't take too much space in the world map, and you might have to generate a planet again if some biome is not appearing, since they have different temperature and humidity characteristics.The game has a small variety of scenarios to choose from, although the core gameplay is the same. Fire and lava are both your worst enemy and your best friend in this biome. The Pyroclastic Conflagration: a volcanic expanse of unrelenting and brutal nature. The Tar Pits: an arid biome rich in vegetation, filled with treacherous tar pits that make movement quite difficult. Inspired by (and compatible with) the Forsakens mod. The Forsaken Crags: permanently clouded by a preternatural darkness, light is the most valuable commodity in this desertic landscape. The Propane Lakes: a frozen wasteland, colder than the most inhospitable Sea Ice, but teeming with aberrant flora and fauna. Almost no food or cultivation in this biome. Apparently an ancient mechanoid attempt at turning the planet into a megastructure.

The Mechanoid Intrusion: a desolate temperate biome with mechanical ruins. No rocks to be found, but plenty of food. The Gelatinous Superorganism: a swampy biome that is actually the upper surface of an extraordinarily large mold-like creature. The Ocular Forest: a weird transdimensional realm intruding upon our Universe.

The Feralisk Infested Jungle: a warm, wet biome with incredibly dense vegetation, filled to the brink with extremely dangerous predatory spiders. The Gallatross Graveyard: an arid temperate biome, littered with the skeletal remains of ancient beasts. Home to the Wildpod and some weird mushroom varieties of usual creatures. The Mycotic Jungle: a warm and humid biome filled with HUGE mushrooms.

The mod has been designed with the Alpha Animals mod in mind, although it is not a requirement. Adds 10 new diverse biomes to your Rimworlds.
