Chaos Space Marines Army Rules

What are Dark Pacts?

Dark Pacts are the bread and butter of the new Chaos Space Marines army rules. Think of them as Faustian bargains, where units can gain powerful abilities at a potentially perilous cost. Essentially, a Dark Pact allows a unit to invoke the favor of the Chaos Gods in exchange for a Leadership test. Pass the test, and your unit gets to unleash hell with additional buffs. Fail, and the Gods exact their price in the form of D3 mortal wounds. It’s a high-risk, high-reward mechanic that perfectly captures the essence of Chaos.

How to Use Dark Pacts Effectively

So, how do you make the most of these sinister deals? First off, timing is everything. Use Dark Pacts at critical moments when the payoff will outweigh the risk. For instance, when you’re about to charge a particularly tough enemy unit, invoking a Dark Pact can tip the scales in your favor. Secondly, know your units’ Leadership scores. Units with higher Leadership are more likely to pass the test, making them ideal candidates for frequent pacts. And don’t forget about icons or characters that can improve Leadership or reroll failed tests. These can significantly reduce the downside of making pacts, allowing you to wield their power more confidently.

Cults of the Dark Gods

Including Berzerkers, Rubrics, Plague Marines, and Noise Marines

Chaos Space Marines aren’t just about spiky armor and evil laughs. The Cults of the Dark Gods add a flavorful variety to your army. These cult units each serve one of the four major Chaos Gods, bringing unique abilities and thematic flair. Berzerkers are bloodthirsty warriors dedicated to Khorne, excelling in melee combat. Rubric Marines, servants of Tzeentch, unleash potent psychic powers and are resilient thanks to their dust-filled suits of armor. Plague Marines, the bloated minions of Nurgle, are tough as nails and can spread debilitating diseases. Finally, Noise Marines, devoted to Slaanesh, wield sonic weapons that can melt faces (literally and figuratively).

Restrictions and Benefits

While these cult units are powerful, they come with certain restrictions. You can’t just flood your army with Berzerkers or Noise Marines; there are limits to how many you can include, ensuring a balanced and thematic force. The benefits, however, are substantial. Each cult unit brings its unique strengths to the table, allowing you to tailor your army to your preferred playstyle. Want to dominate in close combat? Load up on Berzerkers and Plague Marines. Prefer psychic shenanigans? Rubric Marines have got you covered. And if you love blasting your enemies with the power of heavy metal, Noise Marines are your band of choice.

The new Chaos Space Marines codex in 10th Edition enriches the faction with fresh rules and mechanics that stay true to their lore while offering exciting new gameplay opportunities. Whether you’re new to the heresy or a long-time worshipper of the dark gods, there’s never been a better time to pledge your soul to Chaos.

Detachments in Chaos Space Marines Codex

The Chaos Space Marines codex for 10th Edition Warhammer 40k is brimming with new detachment options that cater to a variety of playstyles and strategic preferences. Each detachment brings its own flavor and tactics, making your Chaos army more versatile and deadly than ever. Here’s a closer look at the available detachments and what they offer.

Veterans of the long warVeterans of the Long War

Focus of Hatred Rule

The Veterans of the Long War detachment is all about channeling centuries of bitter rivalry and vengeful fury into precise and devastating strikes. The Focus of Hatred rule lets you choose an enemy unit each turn, granting your units re-rolls to hit against that target. This rule is perfect for picking apart key enemy units with unrelenting accuracy, ensuring no foe escapes the wrath of Chaos.

Key Stratagems and Enhancements

Key stratagems like “Let the Galaxy Burn” provide your units with the ability to ignore cover and cause maximum havoc. Enhancements such as “Warmaster’s Gift” grant your leader critical wound capabilities, making them a force to be reckoned with. These tools ensure your Veterans of the Long War can adapt to various battlefield scenarios with lethal efficiency.

Deceptors

The Deceptors detachment embodies the sneaky, underhanded tactics of the Alpha Legion. With their Infiltration abilities, you can deploy up to three units of Legionaries or Cultist Mobs ahead of the battle. Imagine the look on your opponent’s face when they find the battlefield already swarming with Chaos troops, setting the stage for an early and aggressive engagement.

Unique Enhancements and Stratagems

Renegade Raiders

This mobility keeps your opponent on their toes, unable to pin down your elusive forces.

Dread Talons

The Dread Talons detachment excels in manipulating enemy leadership. Any enemy unit within 12 inches of your models takes a Battle-shock test if they’re below starting strength. This psychological warfare can break the enemy’s morale, causing their units to falter and flee when you need it most.

Battle-shock Mechanics

Strategic Benefits and Limitations

New and Updated Datasheets

Whether you’re a die-hard follower of the Dark Gods or a fresh recruit, the changes in the datasheets are bound to offer something exciting and deadly. Let’s delve into these updates and see what’s in store for your army.

New Units

Chaos Lord With Jump PackChaos Lord with Jump Pack

First on the list of new arrivals is the Chaos Lord with Jump Pack. Picture this: a heavily armored, sinister figure, soaring across the battlefield with a deadly combination of speed and brutality. This guy isn’t just about looking cool; he brings a lot to the table. With the ability to join Raptor squads, he adds much-needed leadership and melee prowess. His “Cruel Hunter” ability allows his unit to pile in and consolidate further, ensuring they stay in the thick of combat where they excel. Equip him with a pair of Lightning Claws, and you’ve got yourself a blender on wings.

Major Unit Updates

AbaddonAbaddon the Despoiler

Abaddon, the ultimate Chaos Space Marine, has undergone some intriguing changes. He’s lost the individual marks of Chaos, now representing Chaos Undivided. This tweak simplifies his integration into various detachments but still allows him to bring his unmatched battlefield presence. His new ability to join units of Chosen makes him even more versatile. Imagine Abaddon leading a pack of elite warriors, tearing through enemy lines with re-rolls to hit and wound. His aura abilities now vary each turn, adding a layer of tactical depth to his use.

Warp Talons

Warp TalonsWarp Talons have received a significant buff that will make them a favorite among aggressive players. These daemonic jump pack troops can now return to reserves if they’re not engaged at the end of the fight phase. This hit-and-run capability allows them to strike hard and then vanish, ready to pounce again later. Their improved melee profile makes them a serious threat to any backline unit.

Possessed

Chaos Space Marines PossessedPossessed have seen both buffs and nerfs. They’ve lost the ability to revive slain models, but their mobility and combat prowess have been enhanced. Now, they can move towards units that shoot at them, potentially closing the gap faster than ever. While their once-per-game Unholy Bloodshed ability might limit their explosive potential, they remain a formidable melee unit with strategic repositioning capabilities.

Weapon Changes

Baleflamer

The notorious Baleflamer is back with a vengeance. This weapon now offers more shots and ignores cover, making it an excellent tool for clearing out infantry and light vehicles hiding in terrain. Auto-hitting with a torrent of flames ensures that anything caught in its path is reduced to ashes. If you like the idea of watching your enemies burn, then the Baleflamer is your new best friend.

Fleshmetal Guns

Fleshmetal Guns, wielded by the monstrous Obliterators, have been tweaked for better performance. Each profile now has a distinct role, making these walking armories even more versatile. Whether you need to melt vehicles with focused malice or shred hordes with warp hail, these guns have got you covered. The shorter range on the melta profile is a trade-off, but their destructive power up close more than compensates for it.

How to Play: Strategies for Playing Chaos Space Marines

Harnessing the power of Chaos Space Marines requires more than brute force; it demands cunning, strategy, and a touch of dark sorcery. Here’s a guide to building and deploying your army effectively.

Building Your Army

chaos space marines new wal horKey Units to Include

When assembling your force, certain units stand out as must-haves. Abaddon the Despoiler provides unparalleled leadership and combat prowess. Warp Talons are perfect for hit-and-run tactics, while Possessed deliver devastating melee damage. The Cultist Firebrand is invaluable for supporting your hordes. Don’t forget about your heavy hitters like Obliterators, who bring versatile firepower to any engagement.

Effective Combinations

Combining units effectively is key to maximizing your army’s potential. Pair Abaddon with Chosen to create an unstoppable force in melee. Use Warp Talons to disrupt enemy lines and force them to react to your movements. Deploy Possessed alongside units like Raptors to create a fast-moving, hard-hitting spearhead. And for a wall of fire and flesh, combine Cultists with the Cultist Firebrand for relentless pressure.

Using Detachments Effectively

New 40k Chaos Space Marine lordChoosing the Right Detachment for Your Playstyle

Each detachment offers unique benefits tailored to different playstyles. If you prefer precision and re-rolls, Veterans of the Long War is your go-to. For those who enjoy outmaneuvering their foes, Deceptors provide infiltration and tactical flexibility. Renegade Raiders are perfect for hit-and-run tactics, while Dread Talons focus on breaking enemy morale.

Maximizing Detachment Abilities

To get the most out of your detachment, leverage their unique abilities. Use the Focus of Hatred from Veterans of the Long War to prioritize and eliminate key enemy units. Deceptors’ infiltration abilities allow you to control the battlefield from the start. Renegade Raiders excel in capturing objectives and retreating before the enemy can respond. And with Dread Talons, constant pressure on enemy leadership can cripple their effectiveness.

Tactical Tips

Dark Pacts can be a game-changer if used wisely. Invoke them at critical moments to gain the upper hand, but always be aware of the risks. High Leadership units and support characters can mitigate the downsides, allowing you to unleash powerful abilities when needed most. Balancing risk and reward with Dark Pacts can turn the tide of battle in your favor.

Utilizing New Weapons and Units

Make the most of the new and updated units and weapons. Deploy your Chaos Lord with Jump Pack to lead rapid assaults and disrupt enemy plans. Use the Baleflamer to clear entrenched positions and Obliterators to adapt to various threats. Warp Talons should be used to harass and eliminate high-value targets, then reposition for the next strike. By understanding and exploiting these new tools, you can outmaneuver and outgun your opponents.
