On Mars: Alien Invasion

A narrative expansion that introduces an alien invasion on Mars and four distinct chapters that change how the base game is played. Each chapter presents a different mode: an asymmetrical one-versus-many scenario, two cooperative scenarios with unique objectives and challenges, and a solo chapter with its own goals. Players follow a short story across the chapters while adapting colony strategies to new threats, events, and win/lose conditions introduced by the expansion. Components and scenarios are designed to integrate with the base game, offering four replayable ways to vary player count and playstyle from competitive to fully cooperative.
