Welcome to Tachyon, the RPG of faster than light space travel, ship-to-ship combat, and daring survival against all odds. In Tachyon, the player or players take on the role of the crew of a space-faring Corvette in service to the United Federation, traveling from planet to planet and system to system to carry out the mission assigned to them, and to endure the trials and tribulations that occur along the way. Engage enemy vessels, trade with fellow travelers, solve local system problems, and explore the charted galaxy at faster than the speed of light!

Tachyon is a product of the Mark of the Odd License derived from Into the Odd.


Tachyon features Save based event resolution, modular ship building, ship to ship combat and boarding, simple character creation and damage calculations, and mechanics for exploration of the stars.

The entirety of the game is available in the preview, lacking only the included adventure, Into Odd Space.  Please use the preview with our blessing.

Is this supposed to be in grayscale?

It is- much of the art is only black and white anyway, and the print version was laid out with black and white in mind. It might cause some inconsistency in the art design throughout, but would you like a pdf inclusive of the original colors?

It is not a super huge deal or anything, just a bit surprising that the thumbnail is in color but the provided pdf is not. If it's possible to get one in color that'd be cool.

The preview appears to be a single page, for character stat blocks.

Appreciated. If you have multiple files uploaded, Drivethru is rather punishing if you update one but do not go back and reset the preview to the updated file, instead defaulting to one of the other files. It is now fixed!

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.
