The widely-renowned werewolf RPG Werewolf: The Apocalypse turns 22 today, celebrating the anniversary of its first edition, released in 1992. Whether you’ve played it—or even heard of it—or not, the RPG has had one hell of an impact on the internet’s werewolf lore as we know it.

The idea of werewolves as guardians of the planet against the evils of humanity? W:TA. Said evils are attributed to the mysterious and malevolent Wyrm in-game.

Werewolves with various “forms?” W:TA. Homid, Glabro, Crinos, Hispo, and Lupus are the names, ranging from “full man” to “full wolf.”

Werewolves with various tribes and rites? Yep.

While the werewolf fandom is frequently at odds in regards to the aspects of werewolf lore that White Wolf brought to the table, the game’s influence is undeniable. I myself have met numerous werewolf-enthusiast friends who recalled either playing or studying the World of Darkness that takes place in Werewolf. Beyond that, the game has been one of White Wolf’s most popular games ever published, even leading to a massively successful Kickstarter a few years ago to publish a 20th anniversary edition release, where they received over 300% more than their goal.

The 20th anniversary release can be purchased from the RPG download store DriveThru RPG in a variety of formats, including PDF, Hardcover B&W, Hardcover Color Premium, and Hardcover Color Standard here. You can also purchase the official 20th anniversary special release of the Werewolf: The Apocalypse cookbook from DriveThru RPG. Yes, really.

Or, if you’d just like to get a basic overview/rundown of the game itself, White Wolf has made available a free 34-page introductory kit PDF. So now you have no excuse to read up on the most widely-recognized werewolf table-top ever.
