If you're already tackling the complexity of On Mars, you know that every small advantage counts when colonizing the red planet. The Beacon Promo Card is exactly that: an additional component that originally appeared as a bonus for retail backers during the Kickstarter campaign. It isn't a standalone game, but rather a promotional card that adds an extra layer of strategy to the base game, allowing players to optimize their moves and find new ways to score points or expand their influence on Mars.

Over time, this card ceased to be exclusive to the initial crowdfunding and became part of the 'On Mars: Alien Invasion' expansion, and was also available during special campaigns like the Game Boy Geek Season 10. For those who enjoy the dense experience of economic management and city building in space, having this card is like adding a piece to a puzzle that makes the game's engine even more intriguing.

Keep in mind that, as a promotional item, it requires the On Mars base game to be functional. It fits perfectly into the worker allocation and point-to-point movement dynamics of the game, bringing that 'expert strategy' flavor that heavy gamers love. If you're looking to maximize your efficiency in Martian colonization and enjoy collecting rare items that shift the table dynamics, this card is a small but potent upgrade for your gaming sessions.
