Warhammer Skulls Festival - Deeds of the Fallen DLC & Onslaught Pack

Battlesector and Gladius are taking part in the Warhammer Skulls Festival, with a new narrative campaign and a major free update for Battlesector and a DLC release for Gladius.

Let's take a look!

Warhammer 40,000: Battlesector



We are really excited to announce that the first narrative campaign DLC, Deeds of the Fallen, is now available on Warhammer 40,000: Battlesector. Featuring 12 new missions and 3 new units for the Sisters of Battle, it's time to bring the fight to Warzone Chaltnath.

On top of this new DLC, we are realising also a new free major update for everyone who owns the base game. The new major update adds a new game mode, Crusade, and also two free units.



Deeds of the Fallen DLC





There hasn’t been new story content from us since our initial release, but this changes today, with the arrival of our new Story Campaign, Deeds of the Fallen.
Deeds of the Fallen contains twelve missions, where fans can play as the Sisters of Battle through a story-driven campaign against the Orks. The Adepta Sororitas will receive three new units, Imagifier, Castigator Battle Tank, Zephyrim - to fight in the name of the Emperor.

New major update



New game mode - Crusade



The Crusade Mode is a new game feature that will challenge players to start with a basic army and fight their way through hordes of enemies, to earn the opportunity to expand both their forces and firepower. The mode also adds a new way to level up the troops, with a new experience system based on the ferocity of the battle, with a variety of ways to upgrade entire classes of troops.



New free units



For this year’s Skulls we wanted to give you some new free units. Last year we sent new forces for Necrons and Tyranids. This time Sisters of Battle and Orks will reap the benefits.

The Adepta Sororitas can now count on the Dominions. The Dominions are specialist assault infantry who excel when making rapid deployments against enemy forces.



While the Orks are gaining the much requested melee version of the Boyz as the lads with Choppas and Sluggas are here and ready for a scrap.



Future



2025 is going to be yet another stellar year for Battlesector. We’ll be regularly updating the game with feature updates and faction balance changes as we go through the year.

There will also be something new, exciting and a bit chaotic coming towards the end of the year…

Warhammer 40,000: Battlesector | Major free update out now

We are thrilled to announce that a new free major update for Warhammer 40,000: Battlesector is available from today, introducing 2 new playable units, a signficant faction refresh for the Sisters of Battle and a new visual face for Planetary Supremacy.

New forces for the Astra Militarum


Today's update will bring new units for the Astra Militarum faction: Leman Russ with Battlecannon and
Cadian Sergeant.

Cadian Sergeant





Due to their role as both leaders and instructors, sergeants in the Astra Militarum are expected to lead from the front, driving their troops to feats of valour and glory. A good sergeant can keep a squad together even under the most dire of circumstances, using their command skills and the earned trust of their troops to quell fear and rally shaken guardsmen under their command.



Leman Russ Battle Tank





The Battle cannon is a larger and heavier version of the autocannon, its size restricting its use to vehicles only. It is the primary weapon of the Leman Russ Battle Tank. It is a formidable weapon whose shells can deal significant damage from a long distance against both vehicle and infantry targets. The sheer power of this weapon makes it an excellent addition to the Astra Militarum's arsenal.



1.04.160 - Patch Notes


Changes since 1.4.138
For those of you who want to know every detail of the new major update, a detailed changelog is available here.

Warhammer 40,000: Battlesector | Dev diary #16 & Major free update release date

Warhammer 40,000: Battlesector - Dev Diary #16 - Sisters and Soldiers



+++ Ecclesiastical Epistle 4298c +++
+++ The Emperor’s Will is made manifest through both Word and Deed +++


We have a few different strands of news to weave together for you today, and a few mysteries to leave in our wake.

Firstly, some new arrivals, landing with a new patch on March 26th!

The Astra Militarum have been fighting and dying in great numbers since their arrival late last year (Guardsmen are the most recruited and most departed unit in the game in the last 3 months) and in the coming weeks they’ll be getting a bit of help.

The initial recruit is for the Armoured Section and is the Leman Russ with its iconic Battle Cannon. This was previously only available on the Tank Commander, but it’s something that a lot of you have asked for, so we’ve now also made it available in a non-commander version.

The next is the Cadian Sergeant. The Astra Militarum is all about the Chain of Command and how that empowers and controls the vast forces of the Imperium, but in the current Astra Militarum lineup there is a very large gap between the vast hordes of soldiers and the Castellan, Commissar and Tank Commander; the Cadian Sergeant will help plug that gap. They are the most affordable command unit we’ve added to the game and will provide reliable buffs and support for Infantry Sections, possibly helping to alter that Kills:Death ratio in the positive direction!

Secondly, a refreshed combat doctrine for the Sisters of Battle.

The Sisters have been in Battlesector in some form since the very beginning, with the rescue from the Landing Pad and the abrupt arrival of Sister Verity on Baal Secundus. They arrived as a full faction soon after that but have rather slipped behind some of the more recent factions when it comes to battlefield performance and unique gameplay aspects.

So, in the same patch at the end of this month that adds the new Cadian units, we are going to be introducing a significant faction mechanic refresh for the Sisters of Battle.

We’ll reveal more later, but it is safe to say that they will be even more closely protected by their Shield of Faith and punch back even harder as they seek Absolution In Battle.

The Third thing to note is that this patch will also bring a new visual face to the Strategy Map for Planetary Supremacy. We have had to take this step as the visual fidelity of this screen has been causing issues for several users and its sheer beauty has meant that we’ve struggled to find ways to get useful information onto the map itself.

The initial approach that you will see in the next update is a significant stripping back of the map, with the beginnings of a new visual language to help teach players about what is behind each of the hex pillars. This is very much just the first step around here and is intended to enable us to add more interest and variety in the future.

And Fourthly and finally, the mysteries.

We have many threads of newness being woven amongst the Battlesector Team. Some of these are now becoming very real and we need some trusted troops to take part in a new private beta test for some exciting developments.

If you are interested in helping us out, you can sign up here.

(Note, PC Steam only for this beta test and you’ll need to already own the base game!)
