"I've spent my career exploring Hostile worlds. It didn't prepare me for Earth: the dust zones, the overcrowded megacities, the shortages of food and water... and the corporations extracting profits from everything around them. No wonder the off-world movement is so popular..."

Earth is a worldbook for the gritty sci-fi Hostile RPG, set in 2225. Two economic collapses have reshaped the world, chaos and crime are widespread, corporations now manage many world governments, and an eco-crisis has created new deserts, flooded cities and changed the atmosphere. If uou're a military contractor, you are in luck! There is much to defend. If you're a corporate agent, then you are fighting for power and profits in the largest super-cities known to man. If you're just trying to get by in your city arcology ... god help you.

Really enjoying this so far. I would probably want to use this with Zaibatsu for American styled cyberpunk. On that note, is there any kind of culture clash between the Zaibatsu street samurai and their American counterparts?

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.
