Boarding Actions Rules Download – Perilous Close-Quarters Battles in the Depths of Space

Back when the Arks of Omen saga began its twisting tale of daemonic schemes and apocalyptic invasions, it introduced a game mode called Boarding Actions. These tense, fast-paced games pitted small armies against each other in brutal room-to-room assaults with highly modular terrain. It was the time for infantry to shine, freed from the presence of war machines and monsters too big to squeeze inside. 

Back then, we promised that Boarding Actions would be supported all the way through the launch of the new edition. It’s time to make good on that promise.

Today’s downloads provide updated rules for playing Boarding Actions games, as well as a comprehensive list of mustering options for your factions of choice. 

The new Boarding Actions Core Rules replace the original ones found in Arks of Omen: Abaddon, adapting the new core rules of Warhammer 40,000 to frantic shipboard battles. However, they’re designed to work with the missions – and mission sequences – presented in all five Arks of Omen books,* giving you dozens of missions and a variety of game modes to play through right from the start.

Several rules referenced by these missions don’t apply to the new edition, but that’s not a problem – the Boarding Actions Core Rules clarify how to handle these situations. For example, Actions no longer exist in Warhammer 40,000, so the new rules explain how to perform and complete any Actions required by your Boarding Action missions. 

In other cases, new rules have been adapted to suit the claustrophobic battlefield. Units can stand on top of objective markers, for instance, just as they did in the previous edition. Some of those corridors would get mighty cramped if they couldn’t!

Another major change comes to Leaders and Bodyguards. The new rules for joining units would make it very easy to hide a powerful champion from harm, so in Boarding Actions, your Leaders don’t join a Bodyguard at all. Instead, they fight solo and confer their powerful Leader abilities to individual units with the new Battlefield Command Stratagem.

Key changes have also been made to the Boarding Actions Mustering Rules, as the Battlefield Roles that previously determined which units you could recruit no longer exist. Instead, each faction now has a simple list that details exactly which units they can select from their free Index, and how many, together with any rules adaptations that apply.

Several factions even gain access to previously-locked options – have you ever wanted to stalk the shadowy corridors with Kayvaan Shrike, or lay down blistering pistol fire with a Seraphim Squad?

These free Boarding Actions Mustering Rules replace those found in the Arks of Omen books – but just like their missions, the faction-specific Enhancements and Stratagems from those supplements remain valid for use. Updates for these books will soon be on their way to ensure that your tricks and tactics work as smoothly as ever.
