In Zombicide: Invader, humanity ventures into space in search of a powerful fuel, Xenium, found on the planet PK-L7. However, this discovery comes with an unexpected threat: the Xenos, alien creatures that launch brutal and relentless attacks. In this cooperative game for 1 to 6 players, you and your friends take on the role of survivors – civilians or soldiers, each with unique skills – in a sci-fi setting overwhelmed by this horde. The goal is simple yet challenging: complete the objectives of the chosen mission, eliminate as many Xenos as possible, and, most importantly, survive! Survivors will work as a team, trading equipment and covering each other, using any available weapon to contain the invasion. The more powerful the weapon, the higher the Xeno body count, but also the greater the attraction of new creatures, intensifying the confrontation. Location is crucial, as conventional weapons work well indoors, but on the planet's oxygen-starved surface, specialized weaponry like lasers are indispensable. The Xenos, though generally predictable, are numerous and employ tactics not seen in previous Zombicide games. Cooperation among players is the key to overcoming challenges and achieving victory in missions.
