Blood and Thunder

Verified differentiators

Features That Change the War

Blood and Thunder is a free browser strategy MMO built around six claims we can prove in code and design docs — not vaporware slideware. Free browser strategy MMO — script your empire or play by hand in a persistent fantasy world that never resets. Free to play in early access.

Scripting Is Legal

Automation is not a ban risk — it is the game. Author city scripts and battle scripts in a readable DSL, or buy proven automation from the Script Marketplace. Authors keep 70%; the platform takes 30%. Everything the UI can do, a script can do.

  • Public API with full UI parity — bots welcome
  • Readable battle / city DSL, not a black-box bot
  • Marketplace for non-coders: tactics for sale, not troops

Double-Blind Auto-Battles

Wars are won by decisions, not click speed. You commit battle scripts before the clash; neither side sees the opponent's plan until the log reveals it. Scout, predict, counter — then let the field resolve while you sleep.

  • Commit once: no mid-battle APM race
  • Hidden scripts force mixed-strategy yomi
  • Scouting buys information — and risks detection

Conquest Governance

Take a city and choose how to rule. Integrate converts culture over time. Preserve keeps foreign buildings and lets you train that race's units. Subjugate extracts harder under a required garrison. Preserve is how mixed-race armies are born.

  • Integrate · Preserve · Subjugate — real tradeoffs
  • Happiness, sabotage, and revolt risk on the conquered
  • Field mixed-race armies under one banner

Ashenmoor mountains — a world that does not wipe

No Resets. No Seasons.

One persistent world. Cities you found, borders you push, and reputations you earn stay. No end-of-round wipe, no forced restart. Progress compounds — and mistakes do too.

  • Always-on fantasy MMO map — not a disposable season
  • Long-horizon empire building with real consequences
  • Play in short sessions; the world keeps ticking

A Living World

AI empires expand through the same public API as human players — and they never attack humans. Bot fleets only target cities where owner_is_ai is explicitly true; missing or false fails closed. The map stays populated; people stay safe from AI aggression.

  • AI empires via the public API — first-class citizens
  • owner_is_ai fail-closed: never target human cities
  • A world that moves even when the lobby is quiet

Anti-Pay-to-Win

You cannot buy troops, resources, or combat power. The Script Marketplace levels the field for non-programmers by selling automation and tactics — never stats. Skill, scouting, and governance decide wars; the shop does not.

  • No cash shop for armies, gold, or research
  • Marketplace sells scripts — not power
  • Fair long-term empire play in early access
