The Demogorgon is coming, and only you can stop it. You can now join Eleven, Mike, Dustin, Lucas, and Will in the Upside Down when you play the new Stranger Things-themed Dungeons & Dragons game, which is available now. Hasbro and Wizards of the Coast have taken a classic board game and revamped it for fans of the original, as well as younger Stranger Things viewers who might not have played the game before.

The starter set comes with an adventure book, character sheets, dice, two Demogorgon figurines (including one that can be painted and customized), and a detailed guide outlining how to play the game. Players will have the chance to choose between characters like Will the Wise and Dustin the Dwarf as they embark on a quest to find the Thessalhydra monster. Both the Thessalhydra and Demogorgon are creatures that actually appeared in the Dungeons & Dragons games of the 1970s and 1980s, but the new Hasbro game’s theme—titled "Hunt for the Thessalhydra"—is based on the adventure invented by Mike’s character in season 1 of Stranger Things.

“Get your fireballs ready as you investigate the mysterious castle and battle the ferocious Demogorgon,” Hasbro writes in its description of the game, which is suitable for people aged 14 and up. Packaged in a retro, worn-looking box, the game is now available on Amazon for $15.99.
