Mothership RPG - Unconfirmed Contact Reports

Unconfirmed Contact Reports is Mothership's answer to the classic Monster Book, with guidance on creating monsters, aliens, and other terrifying horrors. It comes complete with a section on designing your own horrors, and over 40 unique, fully illustrated monstrosities

In Mothership there is a saying: Every monster is a boss monster. That means that each unique horror is a threat that you build 1-3 sessions around, rather than an obstacle meant to be defeated in a single encounter. These horrors are puzzles meant to be solved, ordeals to be survived, or terrors to save innocents from.

Unconfirmed Contact Reports  has taken a novel approach to the classic bestiary style guide. It keeps the stat blocks simple, and instead provides you with first-hand accounts of encounters with its strange and terrifying entities. Each eye-witness account is written to be dropped directly into your game as evidence or clues that you can share directly with your players in game.
