All Hell Let Loose: Great War - coming soon!


I am pleased to announce that after a long period or development and rules writing that a WW1 version of All Hell Let Loose will shortly be published. David and I are in the last stages of tidying things up before we hand over a version to the publisher. We will be running participation games at wargames shows across the UK over the next few months starting with Partizan at Newark on May 17th.

I will be posting more information about the rules over the coming weeks. Today I will limit my post to a very quick summary and high level overview and some pictures of games in action.

We have a very short form to enable those players interested in these rules to register their interest that will enable us to keep you informed on progress and publication. It only takes 30 seconds to fill in and can be found here.


The First World War presents a unique challenge for tabletop wargaming. It was a conflict of enormous scale, industrial firepower, confused command structures, and rapidly evolving tactics. Many rules struggle to capture this without becoming either overwhelmingly complicated or losing the distinctive feel of the Great War altogether.

All Hell Let Loose: Great War has been designed from the outset to balance historical atmosphere with practical tabletop playability.

The rules cover the entire land war from 1914 to 1918, allowing players to fight everything from the open manoeuvre battles of the early war to the heavily fortified offensives of the Western Front, as well as the more fluid campaigns fought elsewhere. Infantry assaults, creeping barrages, tanks, cavalry, gas, fortifications and aircraft all have their place within the system.

At the heart of the game are three core mechanics;

  • Activation
  • Firing
  • Assaults

There are no written orders and bookkeeping is kept deliberately light, allowing players to focus on battlefield decisions rather than paperwork. The activation system creates the uncertainty and disruption so characteristic of Great War command, while remaining straightforward to use.

The rules are intentionally flexible. Players may use a wide variety of figure scales and basing systems, making it easy to adapt existing collections.

Optional “plug-in” mechanics allow groups to decide how detailed they wish the game to become, including expanded rules for preliminary bombardments, artillery barrages, and fortifications.

To help players get started quickly, the book includes sample army lists for the major powers, three introductory scenarios, photocopy-ready counter sheets, and quick reference sheets. The system is equally suited to solo play, smaller friendly games, or large multiplayer club battles.

Ultimately, All Hell Let Loose: Great War is designed to help players recreate the drama, uncertainty, and brutal spectacle of the First World War on the tabletop — without requiring a staff college course to play it.

If that sounds like your kind of game then please register your interest here.

Keep those dice rolling!
