Caustic is an large scale in-progress role playing game that's a bit different every time you play it. Many many things are randomly determined at the creation of a save file, leading to countless possible differences. Sometimes an area will have a different color scheme, or some NPCs will look and act differently. One player's playthrough is near-certain to be different from someone else's. A more personal experience than in most RPGs.
Forever long, there has been a nuclear winter, and the lands have always been known to be ashen snow. The sun has been gone for a long time. A young man named Everett departs on a journey to find the Ossuary, a long abandoned monument rumored to be the one place where the sun still shines.
You can follow the development of this project in these links, if you'd like. It's not a huge thing, really. Reach won't matter to me until the game actually releases, but if you are interested enough in the development, then that's cool.
