Starfinder Adventure Path 20: Attack of the Swarm! Chapter 2: The Last Refuge

Fleeing a world consumed by the ravenous, alien Swarm, the heroes and a handful of desperate survivors limp toward the nearest colony world in a newly acquired starship. After thwarting a mutiny, they reach a large metropolis, where tensions are high. Local fanatics claim the oncoming Swarm is a punishment for the system's sins, disrupting the military's efforts to take in refugees. Worse, a series of caverns below the city that provide the only refuge from inevitable invasion are far from unoccupied, and must be cleared out before time runs out!"The Last Refuge" is a Starfinder Roleplaying Game adventure for four 3rd-level characters. This adventure continues the Attack of the Swarm! Adventure Path, a six-part, monthly campaign in which the heroes fight back against a ruthless and nigh-unstoppable alien invasion. This adventure also includes an early history of the Swarm-spawned shirren race, an exploration of biomechanical starships, and a selection of new Swarm monsters and other harrowing threats.
