Welcome to Slasher, an asymmetrical cooperative comedy horror game built using a vicious, minimalist version of the Mothership RPG system. Slasher is inspired by The Cabin in the Woods, Dead by Daylight, and classic horror movies.

We like to refer to Slasher as a puzzle crawler because you move through each level developing solutions to vanquish or escape from increasingly strong horror villains while collecting more items to assist with future encounters. Direct combat is highly discouraged and will likely lead to death, each encounter is a puzzle in and of itself.

Slasher features a roguelite structure with light character progression and item collection where your party must complete all the levels without a TPK, or they start back at the beginning with brand new characters. However, as long as one person survives a level, your party is able to create new characters to keep moving on to the next.

  • Generated artwork created by idofinternet

    • Rules for custom classes

I bought this at a local game store new. Where can I get a copy of the character sheet, or rules sheet mentioned in the book?

Do you need mothership to use this product?

You do not have to have Mothership for this, it is a standalone hack, but it does have suggestions for how to use your standard Mothership campaign or characters if you would like.

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.
