Off-manifest mission // This game is not set in the Zombienautics universe. Its crew is alive — though not for want of trying.

Mission briefing

Tonight is the Great Harvest. For weeks, the cat god Ulu has whispered to you in your dreams, and now you — a devoted young cultist mouse — finally have your chance to be harvested. There is just one problem: you can’t quite remember how the ritual works.

Explore an old cult manor in isometric view. Talk your way past a grumpy librarian, pester the magister for advice, raid the dining hall for “incense” (stinky cheese will do), and gather what you need to summon Ulu: a burning candle, a raven feather and a circle of invocation drawn in blood.

How you get them is up to you. Ask nicely, improvise with a soot-blackened pillow feather, or deal with the librarian in a much darker way.

Ulu is a picky eater

At the end of the night, Ulu rates the ritual: how well you prepared it, how devout you were and how much help you needed. Six endings await, from a flawless Meowthy Cultist sacrifice to sleeping right through the Harvest. And some of the manor’s residents remember what happened on earlier attempts.

Mission objectives

  • Cute, but sinister. Lovecraftian cult rituals with mice, cheese and a giant cat god. Funny, a bit dark, and unmistakable.
  • More than one way to summon a god. Every ritual ingredient can be found in several ways, and each choice changes Ulu’s verdict.
  • A rating, not a pass/fail. The ending screen awards the ritual a star rating and explains exactly why Ulu was pleased — or disappointed.
  • Made to be replayed. 6 endings, 12 achievements (3 of them secret) and 8 hidden Cats of Ulu. Knowledge carries over between runs, and the characters notice.
  • Built for short sessions. A single run is brief; the Harvest comes round again and again.
