A module for one shot slasher film style survival horror would go perfect with this system.

I picked up Xas Irkalla recently and dig it... a lot. Very cool stuff. But the system isn't quite clicking with me. (But I'm listening to the playthrough from True Mask and it's helping a bit.) Does Strain present the mechanics a bit more clearly? Or, is there another product you have I could give to my players that would help them grok the system prior to the game.

Also, what are the page dimensions for this one if I decide to get it printed?

Thanks! ^__^

Strain doesn't really present the mechanics differently. Strain Basic is probably all you would really need to get the system, everything else just expands on that. The page dimensions for Strain is ANSI Letter (8.5 by 11 inches)

I'm intrigued by this one but $10 for 25 pages seems a bit much. I noticed that you you have pieces of this split off into different books too, so I am curious how this compares to Xax Irkalla with about 5x the content for just $5 more. It really looks like a cool game, I'm just curious about the price differentials and what is included in what else.

Except for the artwork, Xas Irkalla contains everything in this book, and Strain contains everything in Strain Basic, Agony, and Abomination. All of the books have different artwork, with the exception of one piece.

So to be clear, Xas Irkalla contains ALL the content from Strain, Agony and Abomination? What about the content from Alone against the Forlorn Wild?

Yes, Xas Irkalla includes all the content from Strain, Agony, and Abomination, though with different artwork.

The content from Alone Against the Forlorn Wild is not included in Xas Irkalla.

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.
