Indie publisher Isolated Games has released a playable demo for Book & Horn, an upcoming potion-crafting roguelite that pits cauldron-brewing mechanics against relentless waves of monsters.
In Book & Horn, players must brew powerful potions to defend their cauldron from escalating waves of enemies while actively gathering raw materials in real-time. Every run is unique, featuring a deep crafting system where players unlock different potions, each requiring a specific combination of ingredients, alongside dynamic passive abilities in the form of scrolls and power-ups.
The newly released Steam demo gives players access to the full first stage, culminating in a grueling 10-minute survival run and an intense “Nightmare phase.” The demo also introduces a global leaderboard for players competing for the highest score.
“Book & Horn” is scheduled to launch in early access later this year.
