Gonzo: Mad Science


Space Gone Mad

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...
  • New Ships!
    • 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.
    • Mimic Ships!
  • 16 New Weapons
  • 5 New Armors (2 Powered Armor Plus 5 Armor Upgrades!)
  • 6 Other Items (Including Self-Replicating Cubes And Cryopods!)
  • 3 New Consumables (Including an Addictive Invisibility Drug!)
  • 5 New Hazards (Including “The Perfect Song” and the "Walls of Eternity"!)
  • Rules For Intergalactic Siege Weapons!
  • New Skill Uses For Culture (Fashion) And Bluff (Self-deception)
  • 7 New Feats (Including The Infamous “Hold My Beer” Feat!) & 2 New Spells!
  • Plot Hooks Including “The Machine That Will Come”, Werewolves In Space (With Quick-play Lycanthrope Templates For Starfinder), And More!
  • 3 Archetypes (“Power Armor Wizard”, Sniper, And The Aforementioned Macrodeck!)
  • Class Support For Mystics (The “Communication” Connection), Operatives (The Counter-thief Specialization And 2 New Exploits), Envoy (2 New Improvisations), And A New Mechanic Trick!

All This And More! Every One Of The 14 Chapters Could Probably Be Its Own Book!

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
