Before there were expansions.
Before there were settings.
Before there were genres.

There was Chain Reaction.

Chain Reaction 2026 Complete is the definitive edition of the original Two Hour Wargames rules—the foundation on which NUTS!, 5150, Warrior Heroes, and every THW system was built. Powered by the legendary THW Reaction System, this game delivers fast, brutal, story-driven man-to-man combat where you act… and the world reacts immediately.

No turns. No artificial sequencing. No perfect control.

Just decisions, consequences, and survival.

This complete volume reflects years of refinement driven by the THW community and Patreon supporters—players who value games that work solo, co-op, or competitive without special cases, flowcharts, or scripted behavior. The rules reward instinct over optimization and create stories whether you win or lose.

Chain Reaction is:

  • Era-agnostic – modern, WW2, pulp, sci-fi, fantasy

  • Miniature-agnostic – use what you already own

  • Solo-first by design – no AI decks or hidden rules

  • Fast and lethal – games finish in under two hours

Characters aren’t chess pieces. They hesitate. They panic. They charge. They break. They become legends—or names scratched off a roster sheet. Survivors carry their reputation forward, building a living campaign shaped by what actually happened on the table.

This book exists because the THW community asked for it.
It endures because the system works.

Whether you’re a long-time supporter, a returning veteran, or discovering Two Hour Wargames for the first time, Chain Reaction 2026 Complete is the core expression of the THW philosophy:

Let the rules tell the story.
Let the dice decide.
Play the game your way.
