Galaxium: Aliens
The galaxy is not empty. It is hungry.
Galaxium: Aliens is a bestiary expansion for Galaxium, the science-fantasy tabletop roleplaying game of high-tech adventure and cosmic horror. This book adds 100 ready-to-run adversaries built for immediate use in Galaxium campaigns, giving Game Masters a wide range of hostile lifeforms, constructs, infiltrators, predators, war-beasts, cosmic entities, and nightmare threats to drop directly into play.
Inside, you’ll find creatures designed for derelict ships, alien ruins, corporate black sites, frontier colonies, orbital stations, hostile planets, and deep-space horror scenarios. Some adversaries are built to pressure a crew’s resources across a long mission. Others are tactical combatants designed to turn a straightforward fight into a dangerous, shifting battlefield. Some are major set-piece threats powerful enough to define an entire adventure.
Each entry includes a short description explaining what the creature is, how it behaves, and what role it serves in play, followed by a complete combat statblock. Statblocks are formatted for quick table reference and include defenses, initiative, hit points, movement, traits, actions, and when appropriate, bonus actions, reactions, and legendary actions.
Use these adversaries as random encounters, mission bosses, recurring faction assets, biological horrors, engineered weapons, alien ecosystems, security forces, or the unknown thing waiting in the dark. The book also includes creatures organized by type and challenge rating, making it easier to find the right threat for the right moment.
Galaxium: Aliens is built for Game Masters who want more than generic monsters with sci-fi names. These threats are meant to feel strange, dangerous, and tactically distinct. They are evidence that the galaxy has rules of its own, and that the crew is learning those rules the hard way.
In Galaxium, every signal, ruin, and derelict hull might already be claimed.
The only question is what notices the crew first.
Version 14.0.0 replaces previous alien artwork with non-AI assets. This change was made to comply with Foundry’s current content policy. As a result, alien avatars and tokens may look different from earlier versions, and previously placed tokens may no longer match the original artwork.
