Chronicle X is a 1-7 player tactical board game, set in a Sci-Fi Retro 1980s, tasking players to either control the daring men and women that make up the military organization, Chronicle X, or the Overmind, a ruthless and cunning alien overseeing the invasion of Earth and the end of all human resistance. The Chronicle X player(s) have a diverse group of heroes to choose from to form their squad, but must also manage the expansion of their base of operations, using what scraps and materials they can to secure a foothold on the planet. The Overmind player has a cadre of alien troops to choose from to overwhelm the Chronicle X players, ensuring they will never save Earth.
