What it is about

Hidden Action is a table-top, solo and coop game inspired by tactical extraction shooter video games. Built around a fight‑loot‑extract loop, it offers intense, high‑stakes gameplay in which everything can be lost in a single move. Free one-shot scenarios: Hidden Action - The Hunt Hidden Action - The Red Case The Three Pillars First, the HiddenAction engine allows a GM‑less game to feature opponents that follow their own logic and move across the map according to their goals. If you fail to keep a low profile, they may even come looking for you. You never know where they are or what they are doing until your paths cross. Even with all this behind the scenes, the game is easy to run. Second, the game brings the well-established extraction shooter genre to the tabletop. It fits naturally with solo play and provides high replayability. The system allows space for roleplaying encounters, selecting appropriate actions, and deciding their difficulty. The rules act as flexible guidelines to keep the game engaging and challenging. Third, the combat is fierce. Every hit has immediate consequences - reducing effectiveness, causing injuries, and increasing panic unless treated quickly. The decisions you make in the first moments of an encounter often determine who survives. To choose wisely, you must consider many factors, such as the environment and both your and your opponent's gear. Actions may have delayed effects, so you need to plan several moves ahead. At times, the only viable choice is to disengage - if you can pull it off.
