Gonzo: Mad Science brings very “out there” science fiction topics to Starfinder*! We’ve got rules for time travel, black holes, mimic spaceships, werewolves in space, all-consuming nanobots, and more! Much of the content is focused on higher level play and delves into a lot of weird topics in theoretical physics (such as white holes, exotic matter, n-body problems, etc) that is only made stranger with magic!
(*)And, by extensions, Pathfinder if you are willing to convert a few things.
3 New Base Classes!
Replicator: Command a swarm of nanobots to consume and construct things for you on the fly!
Technician: A hacker class that can digitize themselves and create “digital weapons”!
Time Traveler: Unstick yourself from time! Shepherd your group through the time stream, take your turn whenever you want, and even revert to an earlier point in time!
5 New Themes! (Devil Gene, Mindborn, Crisisborn, Sleeper Agent, and Family Reputation)
A New Race, The Chroma
Spiritual humans who, long ago, uploaded a digital copy of their mind to retro, chrome, robots. They use religion-based technology called religiotech; they argue with the universe and, if they are convincing enough, can break the laws of physics.
Included is the extensive “macrodeck” archetype that allows you to use religiotech and a whole new subsystem!
14 New Enemies including:
Chrononites: Beings made of pure time who are assigned to destroy those interfering with the time stream.
Carebots: Bots with buggy programing that were once designed to help people that now try to “help” people a little too aggressively...
Lotan (Tier 20): Chaos incarnate! The legendary impossible ship!
Katzbalder Luxury Liner (Tier 12): Because no one has written a good passenger ship!
Death Gnat (Tier 20): When you absolutely, positively, need to deliver tactical nuclear strikes against a target with a tiny ship; the death gnat is your best (and only) choice.
