Doomsday: A Mad Science Game is a strategy card battler where you play a rogue scientist engineering catastrophic inventions to outsmart rival factions and survive the end times. Combine deck-building with lab management and a branching tech tree to craft unstoppable devices, splice unstable creatures, and chain explosive combos. Every run is a high-risk experiment with procedural encounters, tactical resource decisions, and tough boss fights. Unlock blueprints, refine your lab, and perfect your diabolical engine as you push science far beyond safe limits.
- Build your deck by drafting gadgets, experiments, and creations that define your strategy for the run - Manage energy, materials, and research points to play cards, power devices, and queue laboratory projects - Chain reactions by sequencing cards that amplify each other, triggering status effects and multi-step combos - Research new technologies to unlock blueprints, modify card modules, and specialize your lab into distinct archetypes - Conduct risky experiments to gain powerful bonuses at the cost of instability, hazards, or escalating threats - Read enemy intents, counter faction-specific tactics, and defeat bosses to secure rewards and unlock permanent progression
