Imperium of Man

Space Marines


Captain Titus

Voiced by: Mark Strong

Captain Titus is the commander of the Ultramarines' 2nd Company, and personally takes part in the defense of Forge World Graia. Relatively young for a Space Marine, he is a decorated veteran of several major campaigns, and his exploits have earned him a reputation as one of the mightiest Ultramarines in recent memory. The men under his command are dearer to him than his own life, and if one of them is killed, Titus will not stop until the enemy responsible has paid in blood.

Titus still mourns the recent loss of his mentor, Captain Trajan, who was killed by Eldar in a routine mission Gone Horribly Wrong. Titus held Trajan to be the ideal of Ultramarine nobility and honor. Now that he has inherited command of Trajan's company, Titus aspires to be the kind of leader that Trajan was.

Titus was always interested in the thinking behind his enemy's tactics ever since he first stepped on the battlefield. With every battle, he experienced firsthand how differently each alien species and daemon horde fought on the ground, and gradually, patterns emerged. To better understand the enemy and their motivations gives him insight into their strengths and weaknesses, and into how to exploit those weaknesses in battle. His ability to predict how a group of enemies would attack saved many lives over the years. Now that he’s a Captain, Titus works to instill the same critical thinking in the men under his command.
  • Humble Hero: Titus shows a lot more humility than the average Space Marine; he's very kind and considerate towards the Imperial Guardsmen he meets, often deflects praise away from himself, and at the end of the game, allows himself a Moment of Weakness in front of Lt. Mira.
  • Ideal Hero: Titus is self-sacrificing, humble, heroic and protective of those under his command, whether they're fellow Adeptus Astartes or Imperial Guardsmen. He shows nothing but respect for the Imperial Guard for their unfaltering bravery against titanic odds, and is so pure of heart that he is resistant to the effects of the Warp. He literally answers the prayers of the Imperial Guard with his arrival.
  • Military Maverick: Instead of rigidly adhering to the Codex Astartes, he views it more of a guideline on how to act, instead of it being utter law. This goes against the popular concept that the Ultramarines view the Codex Astartes as sacrosanct, and compared to most Ultramarines depicted, he's the one who deviates from it the most. He's also a Captain and doing this.
  • No-Holds-Barred Beatdown: delivers an epic one to half-demon Nemeroth, ending with him crushing Nemeroth´s head between his hands.
  • Shoulders of Doom: He's a Space Marine, this comes naturally.
  • Shut Up, Hannibal!: Before their battle, Nemeroth tries to convince him to turn to Chaos with promises of power, but Titus' loyalty to the Emperor and the Imperium isn't so easily swayed.


Brother-Sergeant Sidonus

Voiced by: Richard Hawley

Sergeant Sidonus has been a Ultramarine for over 200 years, and serves as Captain Titus' second-in-command. He is also Titus' closest friend and confidant.

He's seemingly seen it all, with a "been there, done that, no problem" attitude and dry sense of humor that instantly serve to defuse tense situations. But when faced with the enemy, Sidonus is their worst nightmare – a brutally efficient warrior who won't stop until every enemy lies dead at his feet.

Sidonus bears the marks of his extended service to the Imperium – including a bionic arm to replace one lost in battle against the Tyranids. When an Eldar weapon destroyed his eye and part of his face, Sidonus decided to leave the scars in place as a reminder of his victory over this formidable enemy.

  • Artificial Limb: His left arm is augmetic, he got it after he lost his original arm fighting against the Tyranids.
  • Badass: One of the times we see him, he's slaughtering several Chaos Space Marines handily and manages to slit a Bloodletter's throat with a Chainsword. Unfortunately, that's also the last time we see him.


Brother Leandros

Voiced by: Noah Huntley

Leandros is the most recent inductee to the Ultramarines command squad. He is a "by the book" Ultramarine, and often speaks with little tact, since to his mind, all actions must serve the Emperor. He looks up to Titus and Sidonus, especially Titus, whom he sees as the type of Ultramarine he aspires to become.

He will question the motives of anyone he suspects of not giving their all for the Imperium, and has lost perspective on what it's like to face the horrors of the universe from a normal human standpoint, and is patronizing to the surviving Imperial Guardsmen he encounters.

He sometimes goes overboard in pursuing what he thinks is a noble course of action, because he wants to prove himself and his abilities.

  • Badass: For all his flaws, Leandros wouldn't have promoted to the Ultra Marines Second Company without being badass.
  • Lawful Stupid: Segues into this at times, like when he calls the Inquisition down on Titus.
  • New Meat: Very young for a Space Marine, he doesn't even have a single service stud yet.
  • Well-Intentioned Extremist: Follows the Codex to the letter, leading to him calling the Inquisition on Titus because of Titus´s ability to resist a ridiculous amount of Warp exposure.

    Tactical Squad Corvus 

Tactical Squad Corvus

A squad of Blood Ravens who joined the Imperial Liberation Fleet, they help Titus reach the Orbital Spire by fighting across a Chaos-held bridge.

Imperial Guard


Second Lieutenant Mira Nero

Voiced by: Christine Roberts

Second Lieutenant Mira leads the survivors of the 203rd Cadian Regiment. Mira's experience and skill as a tactician, coupled with her uncompromising humanity and refusal to give up, commands fierce loyalty among her men.

The 203rd Cadian Regiment was en route to another warzone when their troop carrier was suddenly diverted to Forge World Graia, as they were the only Imperial Guard force close to the planet. The Regiment was the only force that managed to reach the surface before the Orks captured the planet's defense guns.

They were decimated after the Orks cut them off from orbital support and reinforcements, forcing Lieutenant Mira to take command, as she was the highest ranking officer left. All she wants is to save the soldiers she's sworn to lead, but she does not hold much hope of holding off the Orks much longer.
  • Badass Normal: She earned the respect of a Space Marine. Really, that's all that needs to be said.
  • Beauty Is Never Tarnished: Mira's a looker especially in contrast to the craggy, battle-scarred Space Marines and despite being shot at by an army of Orks for several days, the only sign that she's been in a fight is some dirt on her face. She doesn't even have the "tiny scar on the cheekbone" that many fanservicey 40k female characters get. Semi-justified in that her style of fighting has her hanging in the back and blazing away with her lasgun while using YOU as her meatshield.
  • You Are in Command Now: Why is a 2nd Lieutenant in charge of a whole Regiment, normally commanded by a Colonel?
    Mira: I'm all that's left, my lord, unless my commanders rise from the grave. So far, they seem content to stay put.



Inquisitor Drogan

Voiced by: Danny Webb

Inquisitor Drogan is a relentless psyker of the Ordo Xenos, and bears the physical and mental scars of a lifetime spent in the darkest corners of the galaxy.

Many years ago, he fell into the hands of fiendish aliens who tortured him for years. Since then, his hatred of alien species has driven him to develop innovative new ways of destroying them, and to pursue technologies and techniques thought lost or impossible.

His greatest creation is the Psychic Scourge, which channels tremendous amounts of Warp energy, provided by the Power Source, that can be tuned to destroy specific species, while leaving humans unharmed.
  • Evil Is Not a Toy: It's not all that surprising his research with Warp energy would end badly...
  • Fantastic Racism: It's encouraged among the citizens of the Imperium, but his took a level after being tortured horribly by aliens.


Inquisitor Thrax

Voiced by: Mark Lewis Jones

An Inquisitor who accompanied the Liberation Fleet. He appears briefly in the epilogue.
  • Reasonable Authority Figure: While he does take Titus into custody after Leandros accuses him of being tainted by the Warp (He has to, given the severity of the charges and the implications should they be true), the manner in which he does so makes it clear that he's at least considering the possibility that the events leading up to those charges have a more benevolent explanation and that in the immediate term Titus will only be facing an inquiry, not an inquisition.

Enemies of Humanity



Warboss Grimskull

Voiced by: Neil Maskell

Warboss Grimskull leads the Waaagh! invading Forge World Graia, and is extremely cunning. As a result, his Waaagh! is well organized, making it all the more dangerous. He has conquered several worlds before reaching Graia, and if he gets his hands on the Warlord-class Titans on the Forge World, he could be unstoppable.
  • Badass:
    • Dude deserves some credit. He gets dropped at least 50 meters, covered in Bloodletters and crawls back to fight Nemeroth within minutes.
    • He delivers a great Badass Boast in the process.
      Grimskull: [after being thrown into a 50 meter chasm by several Bloodletters] I ain't so easy to kill!
    • He then proceeds to fight Nemeroth.
  • Blood Knight: He's an Ork.
    Grimskull: [upon being swarmed by a veritable horde of Daemons] Haha! You got new friends now, Space Marine!?
  • Boom, Headshot: On the receiving end.
  • Bullfight Boss: A rather difficult one, though he drops it in the third section of the fight.
  • Determinator: When the Chaos invasion begins, Grimskull is swarmed by five daemons and falls into one of the ubiquitous chasms with three of them still attacking him. Then Lord Nemeroth comes along, goes force lightning on your squad and the only thing standing between your squad and death is his monologue. Next, Grimskull jumps back out of the chasm and attacks Nemeroth, uttering the above words. Despite being clearly outmatched, the ork still manages to pull Nemeroth with him when he is yet again thrown into the chasm, thus allowing the Ultramarines to survive. Half a chapter later, he's back up for his bossfight.
  • Genius Bruiser: For an Ork, anyway. His Waaagh! is rather well organized, and he orders them to capture and use the planetary defense guns, instead of simply looting them.
  • Large And In Charge: Would you expect any less from an Ork warboss?
  • Nice Job Fixing It, Villain: He saves you and your squad from Nemeroth... not that he's really bothered either way.
  • Stationary Boss: What he becomes in the third section of his boss fight.
  • The Worf Effect: Downplayed. Gets soundly thrashed by Nemeroth to show off how tough the latter is, but he recovers quickly (see Determinator above).

Forces of Chaos


Sorcerer Lord Nemeroth

Voiced by: Mark Lewis Jones

Nemeroth is the leader of the Chosen of Nemeroth Warband, which is invading Forge World Graia. He is a Chaos Sorcerer Lord with strong psychic powers, and is equipped with Terminator armor and a pair of Lightning Claws. Like most Chaos Space Marines, he is sadistic and arrogant.
  • Clipped Wing Angel: The fight against him while he's transforming is so easy that it's insulting to the fluff, even with Titus' Hand Wave that "Nemeroth is most vulnerable during the transformation".
  • Flunky Boss: Before you take Nemeroth on, you have to fight four waves of his minions. They're more difficult to beat than Nemeroth himself.
  • Knight of Cerebus: The whole plot gets a lot more serious when he's involved.
