Warhammer 40,000: Dawn of War - Definitive Edition Latest Patch Notes - 2.9.0 Update

Although developer Relic Entertainment hasn’t provided a clear 2026 update roadmap thus far, Warhammer 40,000: Dawn of War - Definitive Edition has been receiving regular patches since launch.

Its latest, the 2.9.0 update, focuses on improving multiplayer balance in the later stages of matches. It went live on June 23, 2026, and you can read its full patch notes below:

Multiplayer Balance

Chaos

For Chaos, we’re making some minor tweaks to vehicles as well as buffing the Daemon Prince so that it can have more impact in the late game.

The Defiler changes in update 2.8.0 were too harsh. It will get back its Area of Effect but will have reduced damage, morale damage, and knockback force.

We’re also making the Chaos Space Marines take less time to recover from the morale break status to improve their performance in some matchups. Chaos Space Marines

We have also adjusted other stages of the game, most notably the Falcon can no longer make two Jumps at full charge, and the Avatar now gives less of a bonus to vehicle population cap.

Dark Reapers and their Exarch now get the same bonus from the Optics research in the Soul Shrine to prevent Exarchs from becoming too weak in the late game. This is also a very slight adjustment to the damage output of a full squad of Dark Reapers with Exarch. Full Scale War Research

Seer Council

Infantry Population cost increased from 2 to 3

Imperial Guard

For the Imperial Guard we fixed a bug which was introduced in 2.8.0 where some numbers in the Guardsmen Grenade Launcher and the Weapon Specialization research were wrong.

Guardsmen, Ogryn, and Kasrkin have all received buffs to some weapons to compensate for the reduced bonus from Priests. Guardsmen are also getting some knockback force back on their Grenade Launcher to make them a bit more likely to knock down certain units.

We’re making the Hellhound and the Marauder a bit more accessible and giving back some strength to the Basilisk.

Uncommon Valor has now been split into two research items to allow the Command Squad to be expanded in increments instead of a single expensive upgrade, adding two members at once. Guardsmen

Grenade Launcher knockback increased from 20-30 to 20-35
Plasma Gun damage increased by 15%

Heavy Weapons Team

Health regeneration increased from 1 hitpoint per second to 2 hitpoints per second
Health increased from 650 to 750

Hellhound

Acceleration time decreased from 2s to 1.5s

Basilisk

Damage increased by 10%
Knockback force increased from 28-44 to 30-50

Mechanized Command

Hellhound Depot cost decreased from 100/50 to 50/25
Marauder Depot cost decreased from 50/100 to 50/50

Marauder Bomber * * Vehicle population cost decreased from 4 to 3 * Bombing Run: Krak Bombs ability damage against buildings decreased by 30% * Build time decreased from 38s to 30s Ogryn

Damage of all weapons increased by 15% for Ogryns and their squad leader

Damage of all weapons increased by 15% for Kasrkin and their squad leader

Uncommon Valor

Additional Command Squad members is set to 1
Health increase for Command Squad members is set to 50

Guardsmen Squad Grenade Launchers

The Dark Crusade version of the Guardsmen Squad Grenade Launchers as well as the Weapon Specialization Research were mistakenly used as a base for the changes in 2.8.0. This has been fixed. Affected values: Grenade Launchers Max range was 45 instead of 40 and their build time was 20s instead of 14s. Kasrkin gained x2 damage for Plasma Guns and x1.5 damage for Grenade Launchers from Weapon Specialization instead of the other way around.

Necrons

Necron Warriors have been given a third upgrade which is available in Tier 3. Necron Warriors are now slightly weaker in the earlier stages of the game but end up stronger in the late game where Necrons currently lack scaling of their units.

Attack Scarabs are now cheaper and have lost some of their damage in return for more health and other changes. They should now be better at performing their niche role as anti-air units.

Other notable changes include the cost increase of Flayed Ones to make them less spammable and Tomb Spyders now having a cost of 5 corpses instead of 4 to summon a squad of Necron Warriors. This makes it harder to circumvent their scaling buildtime cost and fill out the infantry cap with just Necron Warriors. Necron Warriors

Gauss Flayer damage against Building Low (mostly Listening Points, Generators, Turrets and Mine Fields) decreased by 10%

Disruption Field

Necron Warriors Gauss Flayer damage increase reduced from 30% to 23%
Cost reduced from 200 to 175 power
Research time decreased from 80s to 70s

Lord Destroyer

Health increased from 1750 to 2000
Stasis Field ability cast range decreased from 30 to 25
Stasis Field duration reduced from 30s to 20s

Orks

Orks have struggled a bit in the early game in some matchups after update 2.8.0. However, in this update we are adjusting some of their tougher matchups and their late game. As such, we are holding off on more changes to the Orks early game for now.

The Fighta-Bomma Grot Bomb is now less dangerous to face and Slugga Boy Squads are now slower to build after they become free due to the More Sluggas research. They also have less health after their second health upgrade to make the green tide less hopeless to face in the late game.

The Killa Kan Rokkit Launcha upgrade should now be more worthwhile and the Squiggoth is now less sluggish while turning. Super ‘Eavy Boy Armor

Slugga Boyz health bonus from +33% to +25%

More Sluggas Research

NEW: Slugga Boy Squad build time increased from 18s to 27s after this research

Fighta-Bomma

Ork Grot Bomb damage, morale damage and knockback force decreased by 20%

Sisters of Battle

The Sisters of Battle have also had a stronger early game than intended after the last update. We are making multiple changes to address this while also fixing some underlying bugs and other issues with the faction.

Battle Sisters are facing some larger changes - we’ve increased their starting squad size by one and raised their cost accordingly. Their build time and reinforce time has been increased to slow down the timings for massing them. The damage from Phosphor Grenades has also been reduced, especially against lighter infantry like Guardsmen.

We’ve also reduced the early game Faith income to limit how often Missionaries and Canoness can use their abilities in the early game. The Canoness has also seen some changes to her Act of Faith abilities - Purifying Light has lower duration while Ascension has been improved to make the Avenging Angels more worthwhile.

Finally, the Inferno turret and the weapons of the Listening Posts now have an area of effect which matches the visuals of the flames. In return, they are losing a large part of their damage and morale damage to compensate. Ecclesiarchal Chapel (Headquarter)

Faith income reduced from 1 to 0.75

Inferno Turret

Twin-Linked Inferno Cannons area of effect increased from 3.5 to 5
Twin-Linked Inferno Cannons damage reduced by 50% except against Commanders and Vehicle Low (lightly armoured vehicles like Sentinel, Land Speeder and Reaver Jetbike)
Morale damage decreased by 30%

Listening Post

The following changes apply to both the Inferno Cannon and the upgraded Inferno Cannon
Area of Effect increased from 3.5 to 5
Damage reduced by 50% except against Commanders and Vehicle Low (lightly armoured vehicles like Sentinel, Land Speeder and Reaver Jetbike)

Immolator

Twin Heavy Flamer morale damage decreased by 20%
Conflagration ability now also deals damage to Commanders, armor piercing set to 50% against Commanders (This ability has 100% armor piercing against infantry so Commanders will take half that damage)

Exorcist

Damage, morale damage and knockback force decreased by 20%
Sisters Repentia Mistress
Bugfix: Sisters Repentia Mistress was not targeted by the Wargear: Blessed Armor and Wargear: Sacrosanct Armor research due to it targeting a Mistress file not in use instead of the correct one. This has now been resolved.

Rhino Transport

Bugfix: Max limit for Rhino Transport wasn’t applying correctly. It now has a proper unit limit of 3 in game. ### Space Marines After update 2.8.0, Space Marines are no longer one of the weaker factions in the game. We’re now focused on adjustments to their mid and late game.

The Chaplain is now cheaper and faster to build while reducing the impact of its healing aura. This should let Space Marines build the unit faster in early T2 when it is really needed while also reducing the strength of its healing which together with heavy cover and Rhino Smoke Launcher made Space Marines incredibly durable. Smoke Launchers have also been adjusted to make T2.5 Space Marines a bit easier to deal with.

Orbital Bombardment is now less likely to wipe out buildings like the Necron generators and the Ork Banners on its own – this makes it less of a game ender when used successfully on clusters of buildings.

The Twin-Linked Lascannon of the Dreadnought should now be worth upgrading to and the Furious Charge of the Grey Knights should now knock away their opponents a more reasonable distance. Assault Space Marines

Melta bomb ability damage against buildings reduced by 15% Space Marine Squad

Twin-Linked Lascannon damage against Vehicle High (Relic Vehicles and a few heavily armored vehicles like the Killa Kan, Baneblade and the Dais of Destruction) increased by 200%

Force Commander

Orbital Bombardment damage against Building Low (mostly Listening Points, Generators, Turrets and Mine Fields) decreased by 30%

Rhino

Smoke Launchers morale and ranged damage reduction decreased from 50% to 40%
Smoke Launchers duration decreased from 30s to 20s

Cost decreased from 260/50 to 225/50
Build time decreased from 57s to 45s
Demoralizing Shout ability duration decreased from 15s to 12s
Chaplain Healing Aura health regeneration multiplier decreased from 4 to 3
Chaplain Healing Aura morale regeneration multiplier decreased from 3 to 2

Terminators and Assault Terminators

Teleport time decreased from 5s/5s to 2.5s/2.5s to teleport/become mobile again. ### Tau We fixed a major bug with the missile projectile of the Skyray Missile Gunship and the XV88 Broadside Battlesuit. They should now be able to hit targets based on the weapon’s accuracy and not miss because a unit moved slightly to the side. To compensate, they’ve lost some of their damage since they turned out to be a lot more effective with this bug fixed. We’ve also adjusted several other Tau vehicles. The Devilfish is now less deadly, the Barracuda deals less damage to commanders and the Drone Squad is now cheaper to build and reinforce.

The Greater Knarlock is now slightly greater than it used to be with better movement and rotation speed making it easier for it to get into the fight. The Krootox has seen similar improvements while losing some of its damage against buildings.

Finally, Fire Warriors now get less range from the Targeting Optics research which should make them a bit easier to deal with. Full Scale War Research

Now requires Kauyon Command Post or Mont’ka Command Post

Plasma Battery Storage Research

Now requires Kauyon Command Post or Mont’ka Command Post

Vespid Stingwing Strain

Damage against Infantry Medium (starting units like Guardsmen, Cultists and Guardians) decreased by 10% on all weapons for Vespids and their squad leader

XV15 Stealth Team

Stealth Team Fusion Blaster and Shas’vre Fusion Blaster damage against Commanders decreased by 25%
EMP Grenade ability area of effect decreased from 10 to 5

Knockback changed from 20-50 to 25-40

Skyray and Broadside Battlesuit

Bugfix: The projectile tau_smart_missile which is used by the Skyray and Broadside Battlesuit lacked a value for Rotation Speed which made the missile weapons of these units unable to track enemy units. Any unit which moved sideways was missed 100% of the time. Rotation Speed is now set to 20 like for the other Tau missile projectiles for the Tau Commander and the Barracuda.

Targeting Optics

Bugfix: Targeting Optics now correctly increases the sight radius of the Shas’Vre by 10 (Squad leader of the XV15 Stealth Team)
