This is a devlog announcing the launch of Usonian Apocrypha, a collection of homebrew for Filled With Online. At the moment, this release consists of a few new character creation options (Advantages, Disadvantages, one basic class and three races), an optional system to reflect a character's creative/investigative abilities with Trades, and a work-in-progress introduction to Estate Raids, a stealth-oriented mode of play where players salvage items from abandoned housing. Additional bits of homebrew may be introduced in updates (though if I make anything else that demands a bunch of extra maps, that'll be its own separate release with pay-what-you-want pricing and higher quality maps at $10 or over.)

By nature, this is noncanonical; the Japanese team is aware of this product but has not had any part in writing it. Still, I'd be pleased if this product at least inspired you to make something new and interesting.
