excluded features in Space Marine 2 that would be perfect for a sequel or DLC, there is a key change that a sequel should definitely make.
While the first two games have followed the exploits of Titus and his band of Ultramarines, it's time that it shifts focus to another Space Marine Chapter, perhaps one that has gone sorely overlooked. The player count on Steam keeps rising, with it becoming the most played Warhammer game of all time, with an all-time peak of 225,690 according to SteamDB. Naturally, this has led Saber Interactive to start looking forward at potential sequels and story-based DLC, with developers already discussing ideas.
Warhammer 40K: Space Marine 3 Should Ditch The Ultramarines
There Are So Many Other Interesting Chapters To Explore
The Ultramarines have long since been the posterchild for both the Space Marines and 40K as a whole, serving as the "coolest" Chapter thanks to its enduring loyalty to the Emperor, cavalcade of impressive characters, and undeniably awesome color scheme. Their popularity has been further cemented thanks to the likes of the original Space Marine game, as well as, undoubtedly, Graham McNeil's incredible Ultramarine book series starring the venerable Uriel Ventris.
However, the 40K universe has so many Space Marine Chapters - about 1,000 in total, although not all are well documented - which are yet to be given the spotlight. While the complete Space Marine 2 roap hasn't outlined what potential story DLC or even a sequel may entail, they should focus on another Space Marine Chapter, or at least prominently feature one.
There are enormous differences between each Chapter, such as the more tribal nature of the Space Wolves, or how the White Scars rely heavily on using Assault Bikes. Pitting these conflicting natures against one another and exploring how much each Chapter relies on the Codex Astartes would serve as an interesting insight into the 40K universe and a deeper exploration of the dynamics between the Chapters.
It's worth noting that the Deathwatch appear in Space Marine 2, although they only turn up for one mission before they're all promptly killed and Titus is reinstated as an Ultramarine. Additionally, other Chapters, including the Blood Ravens, appear briefly in the first Space Marine game.
The Space Marine games have already explored two different Chaos Legions in great detail, as well as Titus' tendency to ignore the teachings of the Codex Astartes. It would be interesting to see how Titus' squad, including Chairon and Gadriel, react to the other Chapters, much like how they were astonished by Titus' stint as a member of the Deathwatch.
However, in order to do this, Space Marine 3 would need to move from the Ultramarines and either put the player in the boots of a different Chapter's Space Marine, or have Titus spend a long time with other Chapters. The Blood Ravens make a great choice here.
Different Space Marine Chapters Have Appeared In Other Warhammer Games
The Blood Ravens Feature Heavily In The Dawn Of War Series
Several of 40K's Space Marine Chapters have appeared in other games as either the main playable faction or as one of many optional factions or characters. This includes the Blood Angels in Battlesector and Space Hulk Tactics, the Dark Angels in Deathwing, the Space Wolves in Rogue Trader, and the Blood Ravens in the Dawn of War series, to name a few.
It's always great to see other Chapters explored, although none have really been given the same level of attention and detail that the Space Marine series affords to the Ultramarines. Often, the Chapter chosen for a 40K game merely denotes what color scheme they have, more than exploring their traditions and beliefs in great detail.
Having a much greater exploration of at least one other Chapter, or potentially several, would easily make Space Marine 3 one of the best Warhammer games ever made, especially if it does those Chapters justice. It would also make sense for multiple Chapters to interact with one another, especially if they were at a large scale event such as the fall of Cadia.

Warhammer 40K: Space Marine 2 Already Has A Huge Problem For Releasing New Classes
The class system in Warhammer 40K: Space Marine 2 offers great variety, but has a fatal flaw that can cause frustration for fans in the future.
There are plenty of story reasons for Warhammer 40K: Space Marine 3 to include multiple Space Marine Chapters beyond the Ultramarines, while still keeping Titus around for players to see his story to the end. Fortunately, Saber Interactive are already playing around with ideas for a sequel, and hopefully the winning one will involve, at the very least, the eternally crusading Black Templars.
The series wouldn't even have to drop Titus as a character altogether, especially after Space Marine 2's shocking ending set up his future story perfectly. Considering how much deeper Warhammer 40,000: Space Marine 2 went into the lore, plus all the unlockable Chapter options for multiplayer, there's a good chance a sequel will include more Chapters in the story.
