Hidden Action - The Red Case

Hidden Action is a table-top, solo and coop game inspired by modern tactical shooter video games. This is a free one-shot scenario based on the original Hidden Action 1.1 game. You have a unique site to explore - a remote, densely forested territory concealing high-tech luxury bunkers. Your objective - locate the red case, and get out. You are not expected to win the game at the first try, maybe not even on tenth. In this game, map knowledge is everything. Success means learning exactly which areas are death traps and where to secure a quick getaway using a hand glider or inflatable boat. Worse, the enemies aren't just waiting for you. You’ll face opponents that traverse the map on their own and try to find you if you are not careful enough – a unique feature of the Hidden Action engine that brings a feeling of a PVP game.
