From publisher blurb:
The Destroyers are the backbone of an invasion from the Sagittarius Galaxy sent to wipe out sentient life in the galaxy. For thousands of years they have attacked mining outposts, taking the raw materials they need to feed their war machine. Strong as some powered armor they are menacing in melee, and effective at range with their Light Machine Gun and Grenade Launcher.
The Adversaries series delivers monsters you can use in your Starfinder campaigns.
This booklet contains:
The Destroyer: a CR 8 creature, including a full stat block, four monster knowledge blocks, each delivering new information at an increasing difficulty. Expanded ecology information about the Destroyers including the logistical support specialist the Destroyer.
