About the game

Welcome, fellow solo wargamer! Oddan's Solo Heresy is a card-driven solo engine built for Warhammer 40,000. A standard 52-card deck removes player bias and brings unpredictability to your games, without complex flowcharts and tedious decision trees. The system is built for speed at the table. You focus on tactical logic first, using the cards to resolve key choices and keep the game moving. It integrates directly into the core game framework, keeping your immersion unbroken from the first turn to the last. I do my absolute best to craft this supplement to a premium standard for your enjoyment, with a clean layout designed to pull you deeper into the grimdark setting. I drew inspiration from official rulebooks and wanted every reader to experience the same aesthetic pleasure from my work as from official materials. What's Inside: Card-Driven AI Engine: A streamlined automated opponent framework powered by a standard 52-card deck. Seamless Integration: Fully compatible with Warhammer 40,000 10th and 11th Editions. Logic-First Resolution: Smart, fast mechanics that keep the battle moving without unnecessary interruption. Deploy your army, and dare to conquer Oddan’s Solo Heresy! —description from the designer
