Machina Arcana is a board game released in 2014 for 1–4 players, 150 minutes per game, and ages 13 and up. It was designed by Juraj Bilich and its main mechanics are Dice Rolling, Grid Movement, and Cooperative Game.
In Machina Arcana, players take on the role of explorers who are investigating an ancient subterranean complex of unknown origin. They face monsters inspired by H. P. Lovecraft's Cthulhu mythos in a steampunk setting. The adventurers collect equipment, interact and utilize their environment, fight monsters, and immerse themselves in the rich narrative elements. The complete story is broken down into different scenarios that represent a self-contained game. All of these scenarios contain chapters, each with its own narration and specifics. The objective of the game is to progress through the tale and face the endgame at the finale of each scenario. The main goal behind Machina Arcana is to provide players with a chilling game that can never be played the same way, mechanisms that enable varying strategies and approaches, and an extensive framework that combines everything smoothly. The game scales by default; there is no need for special conditions based on the player count. As the story progresses, so does your gear. But beware! If you are too slow, horror might very well prevail and devour you whole...
