The Last War

2085. Humanity faces extinction. Alien insects from the edge of our solar system, long hidden behind the façade of reality, descend to enslave us. Hordes of unspeakable horrors roll out from Central Asia, laying waste to anything in their path. The church of the fish-god scours the world for lost occult secrets to unleash terrible forces. Dead gods awaken and turn their dreadful eyes toward the Earth. And within hides a cancer, eating away at the very heart of the New Earth Government. This is the Aeon War.

This is the time of CthulhuTech.

Climb inside a thirty-foot tall war machine and rain down hell on the unwavering Migou. Fight tooth and nail on the front lines against the horrific beasts of the Rapine Storm. Seek out the disgusting corruption of the insidious Esoteric Order of Dagon. Explore the dark world of the malignant Chrysalis Corporation and their unseen monstrous agents. Sift through secrets long thought lost and bend the power of the cosmos to your will. Join in symbiosis with something beyond time and space and become a shape-shifting bringer of wrath. Nowhere else will you find a setting like this.

Inside this book you will find:

  • a complete history and detailed exploration of the world of the Aeon War, so that you can start a game right away.
  • nine pieces of provocative short fiction to help portray the feel of the setting.
  • the innovative Framewerk system. Not only cinematic, Framewerk puts control back where it belongs – in your hands.
  • the option to play a hardy and resourceful 21st century Human or join the fight as a night-skinned genetically-engineered Nazzadi.
  • the option to play as one of seven professions, including Arcanotechnicians, who meld technology and magic into a unique discipline, Engel Pilots, who join in communion with gigantic arcane cyborgs, Occult Scholars, who delve into the mysteries of the universe and harness its power for themselves, or the mysterious alien shape-shifting Tagers.
  • a unique ritual-based magic system, simulating dark and painstaking universe channeling power, including two dozen mind-wrenching spells.
  • more than 30 unique machines of death, including the bug-like Migou mecha, the rough and tumble mecha of the New Earth Government, and the monstrous bio-organic Engels.
  • more than 20 unspeakable horrors, including the terrible hordes of the Rapine Storm and the monstrous servants of the Chrysalis Corporation.
  • a secret history of the world for Storyguides, including an exploration of dead gods, lost races, and forgotten places.
  • story starters and hooks, to get you into a game now. CthulhuTech is a complete, self-contained storytelling game. All you need besides this book are five to ten 10-sided dice.

If anyone's curious V2 isn't dead just in quiet development. Wildfire's got a Discord server and are apparently going to launch a Kickstarter campaign at some point in the near future.

It still is a very good game. I've played several others, but my best memories so far have been with cthulhutech. There is something in the Ctech universe that I haven't seen in other games.

I played this when it was first released for 2 years. It would seem much of the D&D and Anime crowd trashed it. It was brilliant. It took series like Robotech, Neon Genesis, Cyberpunk, and Guyver and gave it new life. I’d didn’t use everything in the book. Mostly the Engles, Mechs, Zabers. I played it out as an invasion. This game needs a 2.0

Are there any plans to update the PDF to the Sandstorm Studios revision?

I purchased the Softcover Color Book (Standard) and was a little disappointed with the print/bindery quality.

The book is printed on non-glossy paper, which is unusual for an RPG rulebook. It's functional... But doesn't pop as much as my other rulebooks do. Which is a shame since there's some fantastic artwork in there.

There's some fairly heavy background art on every page - kind of dirt and smudges and stuff. It adds to the overall aesthetic, but it can make some text un-necessarily hard to read.

The biggest issue, by far, is the lack of an inside gutter. Due to the way the book is bound and how the pages bend, the inside edge of the page is very difficult to read.

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.
