New Boarding Action rules for fighting on an Ark of OmenBelow, you’ll find new rules for
Boarding Action games set on the
Herald of Misery, one of Abaddon’s monstrous Arks of Omen. This suite of rules includes
Warp-infected Entity tiles (which you’ll find on the card section included in this issue) and six intense new missions. While these missions are part of the ongoing story of the Arks of Omen, you can, of course, play them as one-off games using any army. You could fight a battle where the Tyranids and the Necrons clash over an infected space hulk, for example. Not a tasty meal or a worthy prize, perhaps, but the Hive Mind and the Silent King work in mysterious ways. However you choose to play these missions, we wish you the very best of luck as you board the
Herald of Misery!
Untamed Ark Missions
When playing an Untamed Ark mission, follow the
Mission Sequence laid out in
Arks of Omen: Abaddon, with the following additional rules:
- In the Determine Mission step, use the table below to determine which mission to play instead of the one found in the book.
All of the missions in this issue use the additional
Warp-infected Entity tiles; the rules for these can be found below. In the
Create the Battlefield and Place Objective Markers step, the Warp-infected Entity tiles are placed face down and shuffled, before each is randomly placed face down on the battlefield (without either player looking at the tiles face), with one on each of the marked Warp-infected Entity Zones.
Warp-infected Entity Tiles
The missions presented in this issue feature new pieces of terrain to include on your
Boarding Action battlefields called Warp-infected Entity tiles. On one face, these six tiles all feature a blank, featureless hole leading to the decks far below, the floor having been ripped out in some past battle. The other face depicts different parts of the giant mutant entity that infests this untamed Ark.

At the start of the battle, all of these Warp-infected Entity tiles are placed on the battlefield face down as outlined above. The mission’s rules will then specify at what points you should turn these tiles over and how many of them to do so. Only then will you discover what parts of this unfathomable denizen strike where.
When placing a Warp-infected Entity tile, line it up with the inner square at the centre of the Zone it is placed on, as shown here.
Warp-infected Entity tiles do not block
visibility, and each time a model moves, at no point can any part of its base move across a Warp-infected Entity tile, regardless of which side of the Warp-infected Entity tile is facing up.
The rules associated with each Warp-infected Entity tile are shown below.
Hypnotic Gaze
Disturbing Presence: When this Warp-infected Entity tile is turned face up, any
actions being performed by units that are within 4" of and visible to this Warp-infected Entity tile automatically fail, and any of those units that are
Set to Defend or
Set Overwatch are no longer in either of those states. While a unit is within 4" of and visible to this Warp-infected Entity tile, that unit cannot
perform actions.
Malefic Gaze: While a unit is within 4" of and visible to this Warp-infected Entity tile, that unit’s controlling player cannot
re-roll any rolls made for that unit or models within it.
Barbed Maw-tendrils
Mindless Feeding: When this Warp-infected Entity tile is turned face up, and at the end of the battle round, roll one D6 for each unit within 4" of and visible to this Warp-infected Entity tile: on a 1, that unit suffers 2
mortal wounds; on a 2-5, that unit suffers 1 mortal wound.
Flailing Pseudopods
Mucal Mire: At the start of the
Movement phase, roll one D6 for each unit within 4" of and visible to this Warp-infected Entity tile: on a 1-3, until the end of the turn, halve the Move characteristic of models in that unit and halve
Advance and
charge rolls made for it.
Diseased Vent
Necrotic Exhalations: While a unit is within 4" of and visible to this Warp-infected Entity tile, each time a model in that unit makes an attack, subtract 1 from that attack’s
hit roll.
Heaving Flesh
Corrosive Emanations: Each time an attack is made that targets a unit within 4" of and visible to this Warp-infected Entity tile, improve the Armour Penetration characteristic of that attack by 1.
Kill It, Burn It, Destroy It: At the end of a player’s turn, if they have one or more units within 1" of this Warp-infected Entity tile, they can select one of those units to attack the mutant entity at this Warp-infected Entity tile. If they do so, roll one D6: on a 1-2, the attacking unit fails and suffers 1
mortal wound; on a 3+, the attacking unit is successful. If the unit is successful, the mutant entity is injured and recoils from the attack; remove all Warp-infected Entity tiles from the battlefield. Then the Warp-infected Entity tiles are placed face down and shuffled, before each is randomly placed face down on the battlefield (without either player looking at the tiles face), with one on each of the marked Warp-infected Entity Zones. Finally, roll two D6s, re-rolling any duplicates or any that correspond to the Warp-infected Entity tile position that was just attacked; turn those Warp-infected Entity tiles face up.
MISSION BRIEFINGWarsmith Czagra had minutely plotted his mastering of the Herald of Misery. Throughout the Ark of Omen, his sub-commanders pushed forward to claim the vessels vital systems and purge the surrounding decks of savage denizens. Ever was the ship-sized monstrosity a threat to all as it heaved its way through the Arks metal flesh. Where it could not be avoided, desperate efforts were made to drive it from secured areas.MISSION RULESPredatory Mutant Beast: At the start of the first battle round, turn the
Warp-infected Entity tiles in locations 2 and 5 face up. From the second battle round onwards, at the start of the battle round, roll two D6s, re-rolling any duplicates or any that correspond to a Warp-infected Entity tile that is already face up; turn those Warp-infected Entity tiles face up.
Underdog Bonus: If a player receives an Underdog Bonus, that player starts the battle with 1 additional
Command point.
OBJECTIVESSEIZE THE ARK’S SYSTEMS
Progressive Objective
Without control of the Ark’s insane and daemon-twisted systems, the agglomerate vessel would be going nowhere - leaving its would-be master unable to fulfil his side of Abaddon’s bargain.
At the end of each player s
Command phase, the player whose turn it is scores 5 victory points for each of the following conditions they satisfy (for a maximum of 15 victory points):
- They control one or more objective markers.
- They control two or more objective markers.
- They control more objective markers than their opponent controls.
This objective cannot be scored in the first battle round. In the fifth battle round, the player who has the second turn does not score any victory points at the end of their Command phase; instead, at the end of their turn, they score 5 victory points for each of the above conditions they satisfy (for a maximum of 15 victory points).
RECOIL IN PAIN
Progressive Objective
Though seemingly mindless, the gigantic mutant entity posed lethal risks as it lashed out instinctively. Only the most devastating wounds that gouged huge craters in its flesh reached its twisted senses and drove it back. Such triumphs were short-lived, as its pulsating and writhing mass re-knit such rents with ease.
Each time a unit from a player’s army successfully attacks the mutant entity (see Heaving Flesh), that player scores 10 victory points.

MISSION BRIEFINGLurking within a deep chamber that served as both the Ark’s bridge and the creature’s lair was the daemonic Ferryman of the Herald of Misery, a being supposedly bound to obey the Ark’s master. Yet locating the Ferryman’s chamber was no easy feat. Czagra’s cybertheurges discovered a chain of psychic keystones whose activation, they divined, would unveil the Ferryman’s location. The Warsmith deployed some of his most brutal boarding parties to crush anything that barred his way to them.MISSION RULESLurking Mutant Beast: At the start of the first battle round, turn the
Warp-infected Entity tiles in locations 3 and 4 face up. From the second battle round onwards, at the start of the battle round, roll one D6, re-rolling if it corresponds to a Warp-infected Entity tile that is already face up; turn that Warp-infected Entity tile face up.
Underdog Bonus: If a player receives an Underdog Bonus, that player starts the battle with 1 additional
Command point.
OBJECTIVESKEYSTONE CONTROL
Progressive Objective
While some of the Ark’s savage denizens avoided the unnatural emanations of the warp-attuned keystones, others were drawn to them. They defended their territories with wild avarice or fanatical devotion, while the Iron Warriors strove to eradicate them in mass culls.
At the end of each player’s
Command phase, the player whose turn it is scores 5 victory points for each of the following conditions they satisfy (for a maximum of 20 victory points):
- They control one or more objective markers.
- They control two or more objective markers.
- They control more objective markers than their opponent controls.
- They control the Prime objective marker.
This objective cannot be scored in the first battle round. In the fifth battle round, the player who has the second turn does not score any victory points at the end of their Command phase; instead, at the end of their turn, they score 5 victory points for each of the above conditions they satisfy (for a maximum of 20 victory points).
TERRITORIAL RIVAL
End Game Objective
Whether the feral champion of one of the Ark’s pack-like tribes or an ambitious rival seeking to rise in the Warsmiths favour, enemy leaders were regarded as worthy offerings to the Dark Gods as well as strategically sound targets.
At the end of the battle, each player scores 10 victory points if their opponent’s WARLORD is destroyed.

MISSION BRIEFINGAs the Warsmith’s strike forces pushed ever deeper into the Ark’s bowels, through fragment after fragment of crushed and twisted wrecks, encounters with the immense beast became sudden and unheralded. Even as the Iron Warriors evaded its clutches, there were ferocious battles with increasingly bold or desperate denizens. They were as eager to expel the Legionaries from their domain as Czagra’s warriors were to carve out new bases of operations.MISSION RULESLunging Mutant Beast: From the second battle round onwards, at the start of the battle round, roll three D6s, re-rolling any duplicates or any that correspond to a
Warp-infected Entity tile that is already face up; turn those Warp-infected Entity tiles face up.
Underdog Bonus: If a player receives an Underdog Bonus, that player starts the battle with 1 additional
Command point.
OBJECTIVESEMPIRE BUILDING
Progressive Objective
As they sought to expand their territories or lay claim to strategically significant sites, both forces attempted to establish cohesive power bases.
At the end of each player’s
Command phase, the player whose turn it is scores 5 victory points for each of the following conditions they satisfy (for a maximum of 25 victory points):
- They control one or more objective markers.
- They control two or more objective markers.
- They control more objective markers than their opponent controls.
- They control both objective markers labelled A.
- They control both objective markers labelled B.
This objective cannot be scored in the first battle round. In the fifth battle round, the player who has the second turn does not score any victory points at the end of their Command phase; instead, at the end of their turn, they score 5 victory points for each of the above conditions they satisfy (for a maximum of 25 victory points).

MISSION BRIEFINGRuthlessly analytical, Czagra’s Iron Warriors learned to read some of the mindless beast’s telltale signs and attempted to identify areas in which it was particularly active. Their coldly calculating ability to weaponise their chosen battlefield saw them lure their enemies into dangerous reach of the creature in numerous confrontations.MISSION RULESMutant Beast Territory: Before the battle, in the
Create the Battlefield and Place Objective Markers step, instead of placing the
Warp-infected Entity tiles randomly, the Defender looks at each of the Warp-infected Entity tiles and secretly places each one face down on one of the relevant Warp-infected Entity Zones that does not yet have its Warp-infected Entity tile. From the second battle round onwards, at the start of the battle round, roll two D6s, re-rolling any duplicates or any that correspond to a Warp-infected Entity tile that is already face up; turn those Warp-infected Entity tiles face up.
Dug In and Readied: The Defender has the first turn.
Underdog Bonus: If a player receives an Underdog Bonus, at the start of the first battle round, that player can select one unit from their army to make a
Normal Move of up to 6".
OBJECTIVESTERRITORIAL CAPTURE
Progressive Objective
The regions of the Ark in which the mutant entity was most active were viewed as blessed with dark power by some of the denizens. To others, they afforded the opportunity to plunder the chasms opened up by the beast’s passage. The Iron Warriors, meanwhile, saw only the need to purge these regions of resistance and to continue the grinding acquisition of yet more of a vessel they already viewed as belonging to Czagra.
From the second battle round onwards, at the end of each player’s turn, the player whose turn it is scores 5 victory points for each of the following conditions they satisfy (for a maximum of 15 victory points):
- They control one or more objective markers.
- They control two or more objective markers.
- They control more objective markers than their opponent controls.
AGGRESSIVE LINEBREAKERS
End Game Objective
Spurred on by vengeance, bloodshed or whispered urgings in their minds, forces of all kinds sought to break their foes’ battle lines or die trying.
At the end of the battle:
- The Defender scores 5 victory points for each Prime objective marker they control.
- The Attacker scores 10 victory points for each Prime objective marker they control.

MISSION BRIEFINGAs Czagra’s warriors punched brutally through one wreck fragment after another, they learned from the slaves they took of the deification of the mutant monstrosity by some cults of denizens. Against these foes, Czagra orchestrated devastating assaults that focused on inflicting violent and hugely symbolic wounds on the creature wherever its bulk appeared. To the cults who opposed him, the message was clear: there was room for only one object of awe and fear on the Herald of Misery, and that was Czagra himself.MISSION RULESRampant Mutant Beast: At the start of the first battle round, turn all
Warp-infected Entity tiles face up.
Vanguard Fanatics: Once the first battle round has started, the Defender cannot use their Patrol Entry Zones when setting up any
Strategic Reserve units from their army in an Entry Zone.
Maul the Beast: The Attacker can attack any Warp-infected Entity tile, as outlined in the Kill It, Burn It, Destroy It ability, not just the
Heaving Flesh tile. Each time the Attacker successfully attacks the mutant entity in this manner, that tile is turned over, and the sequence ends - the mutant entity does not recoil from the attack, and all other Warp-infected Entity tiles remain as they are.
Underdog Bonus: If a player receives an Underdog Bonus, that player starts the battle with 1 additional
Command point.
OBJECTIVESSUBJUGATION OF BELIEF
End Game Objective
Every plume of tainted gore and every severed proboscis eroded the faith of the monstrous entity’s worshippers, while every failure strengthened their belief in its abhorrent omnipotence.
At the end of the battle:
- The Attacker scores 15 victory points for each Warp-infected Entity tile that is face down.
- The Defender scores 15 victory points for each Warp-infected Entity tile that is face up.

MISSION BRIEFINGDesperate survivors were hunted mercilessly through the Ark’s shifting geometries by ceaseless attackers and pushed back to their last-ditch holdout. Death was on the air, a bloodlust that saturated the Ark’s very fabric. The hunters roared their aggression, and the defenders, with nothing left to lose, prepared to sell their lives as dearly as possible. The deckplates groaned and bulged, the massive entity within seething with hunger.MISSION RULESThrashing Mutant Beast: At the start of the battle round, roll three D6s, re-rolling any duplicates; turn those
Warp-infected Entity tiles face up. From the second battle round onwards, at the start of the battle round, turn any face-up Warp-infected Entity tiles face down and any face-down tiles, turn face up.
Underdog Bonus: If a player receives an Underdog Bonus, that player starts the battle with 1 additional
Command point.
OBJECTIVESBLOOD-SOAKED CONTROL
Progressive Objective
In the battle for control of the Ark, it was not enough to simply engage the enemy and rout those with cowardice in their hearts. The eradication of the foe needed to be methodical, structured and thorough. Every bolthole needed to be seized and every chamber purged.
From the second battle round onwards, at the end of each player’s turn, the player whose turn it is scores 5 victory points for each of the following conditions they satisfy (for a maximum of 10 victory points):
- They control one or more objective markers.
- They control two or more objective markers.
STATEMENT OF DOMINION
End Game Objective
The final sweeping purge was a statement to the Dark Gods and to the spirit of the Ark itself. Mastery, it proclaimed, is seized by the strong.
At the end of the battle, each player scores 10 victory points for each objective marker they control.
