Originally announced in 2018 (see Men in Black and Ghostbusters Team Up), Ecto-Terrestrial Invasion is a semi-cooperative board game in which players pair up members of the Ghostbusters and the Men in Black and compete to bust the most ecto-terrestrials, which have invaded the world after their ship crashes into the Ghostbusters iconic firehouse.
The ecto-terrestrials are controlled through the games AI rules and a multi-chamber dice tower representing the firehouse. The players compete to capture the best targets, earning cash for their efforts, but they must be careful not to compete too aggressively or the ecto-terrestrials will become too powerful and all the players will lose the game.
The game will feature a story-driven campaign for players to confront, written by Ghostbusters comic writer Erik Burnham. The campaign has a branching storyline that develops based on decisions the players make at various points during the campaign.
