Action Girl: Second Lieutenant Mira, leader of the remaining members of the 203rd Cadian regiment, at your service.
A Father to His Men: Captain Titus is nothing but respectful and protective of his subordinates. He does not condescend on the Imperial Guardsmen (which would be understandable enough for a Space Marine Captain, who is MUCH higher on the Imperial totem pole), instead commending them for their bravery and thanking them for their support as the mission goes along. Since this is 40K, they in turn practically worship the ground he walks on. As the Ultramarines are one of the more benevolent Space Marine chapters toward common humans, this is nothing out of the ordinary.
You always revive with full health, even if you were beaten to a pulp before or during the autosave.
In the multiplayer, when you are killed by someone, you have the option to respawn using their gear and perks instead of your own. This gives low-level players a fighting chance against their higher-leveled killer(s).
If you empty a bolt weapon's magazine, you will reload automatically, but more slowly than if you reloaded manually before you ran out. When the magazine's about to run out, it makes a metallic, clinking sound, which lets you know so you can perform a quick reload without having to look at your ammo counter. This is EXTREMELY useful, since the game's chaotic pace makes a distraction as tiny as looking at your ammo count potentially fatal.
One of the logs that averts this turns out to be a Crowning Moment Of Heart Warming. An Imperial Guardsmen heard a noise in a pipe and was about to throw a grenade in it - until he found that it was a group of surviving civilians. He then describes it as one of the happiest moments he's ever had.
Ascended Extra: Titus and Sidonus actually appeared in the tabletop game first as nameless miniatures, specifically the only two helmetless members of an Ultramarines Sternguard Veteran box set. Titus being a Sternguard Veteran before being promoted to Brother-Captain actually makes a great deal of sense, considering they specialize in using a variety of exotic guns.
Surprisingly downplayed, at least with Titus' character. He does not resemble the codifiers (Gears of War, Halo, Doom, etc.) at all, being a well-spoken, experienced commander who leads the assault instead of bringing up the rear. The rest of The Squad vary in how well they fit the trope. However, every plot element of A Space Marine Is You is in full force and then some.
Attack! Attack! Attack!: With the exception of the few Orks that have long-ranged weapons or actually stay in one spot to shoot, this is essentially the only "tactic" the Orks use.
Awesome, but Impractical: Executions against larger enemies like Chaos Space Marines. While satisfying and useful for the health regeneration, these take longer than normal executions and leave Titus vulnerable to other attacks, possibly cancelling out the health regained. Basically, just killing large enemies is a lot less hassle unless there's few enemies left or you're desperate for the health.
Axe Crazy: Chaos Space Marines, especially those wielding Chain Axes.
The best example of her badassery is not that she managed to hold off an Ork Army long after the Ultramarines thought the Guard would be wiped out, but that she engages in light snarkery with a Space Marine Captain and gets away with it. Keep in mind that your average Astartes is 8 to 10 feet tall and strong enough to crush a normal human's skull like it was an egg, not to mention the fact no one in their right mind would speak up if said Astartes decided to crush said head like said egg.
World of Badass: It's Warhammer 40K. If you're not a badass, you're probably already dead.
The Chaos Space Marines count too, and WILL tear you limb from limb if you're not careful. One of the Aspiring Champions can handily stand up to Titus blow for blow, too.
They only show up briefly, but the Blood Ravens, our old friends from Dawn of War, are no slouch, charging at the Chaos lines fearlessly. All the more so since they weren't ordered into the fight, they just happened to be in the neighborhood and decided to come help.
The Heavy Bolter, Lascannon and Plasma Cannon, to name a few. This is also the purview of the Devastator Marine/Havoc multi-player class, wielding them to mow down opponents from a distance.
Even the regular Bolter counts as one. When Titus first picks one up, the description says his is .998 calibre which dwarves most other Bolters that use a still whopping .75
The giant gun fortress preventing Imperial ships from landing (the shells are about the size of a bus), and the crane-suspended Volcano cannon (meant to be mounted on a Titan) that the orks tried to rig to break down a massive gate.
Big Bad: Warboss Grimskull, leader of the Ork Hordes.
Big Damn Heroes: You and your squad. The Guardsmen all view you as this when you come charging out of nowhere to help them fend off huge Ork and Chaos assaults.
Big Damn Villains: When all seems lost, Nemeroth has seemingly killed Warboss Grimskull and has our heroes on the ropes, the Warboss proves he is not quite as dead as the Chaos Sorcerer would like to think. The ensuing fight allows the Marines to escape.
Bittersweet Ending: Over the course of the game, Titus brings an Ork Waaagh! grinding to a halt, stops a Chaos invasion in its tracks and beats a Daemon Prince to death with his bare hands while in free fall from a Space Elevator... only to be taken away by the Inquisition while being flanked by Black Templars because Leandros, his own battle brother, accused him of heresy due to suspicions that arose over the events of the game.
The thing that keeps this from being closer to a Downer Ending lies with Inquisitor Thrax. He clearly doesn't take Leandros seriously, and is simply going through the motions that he's officially required to. If he actually thought Captain Titus was a heretic, he would have had Mira and Leandros detained as well, wouldn't have let Titus deliver his "The Reason You Suck" Speech to Leandros, and certainly would have had him disarmed before letting him on board the transport considering the sheer amount of destruction he was just responsible for.
Also how Titus kills Grimskull, with a Plasma Pistol shot.
Boring, but Practical: In the campaign, the standard Bolter is reliable, holds a lot of ammo, and deals a fair amount of damage. Once it's upgraded to a Kraken Bolter, even moreso.
The Bolter combined with the Kraken Bolts perk is frequently seen online, for more or less the same reasons as in the campaign.
Bottomless Magazines: Played with. The plain vanilla Bolter has unlimited rounds and one of the largest clips, but still has to be reloaded.
Butt Monkey: Gretchin and Chaos militia. The best these two can hope for is literally being slapped to death by the Emperor's Angels of Death.
By-the-Book Cop: Leandros is a military example, see Bittersweet Ending above and Foreshadowing below. Note that his decision was right from the legal standpoint. Possibility of a Chaos taint in high-ranking Adeptus Astartes officer is a grave danger indeed.
Though his reasons are indeed justified by the codex, his actions aren't entirely in line with protocol. Normally he would have raised his suspicions to a Ultramarine Chaplain, not an inquisitor.
Character Customization: The player may customize their Marine's armour with different pieces and colours, and choose specific options within the Tactical Marine/Chaos Marine, Devastator Marine/Havoc and Assault Marine/Raptor classes in lieu of weaponry, perks and equipment. The customization system is said to have over 1.8 billion combinations.
A minor one, Imperial Guardsmen can grudgingly repair their own vehicles. This ability was introduced in Dawn of War II: Retribution.
"The Omnissiah won't like this."
Critical Existence Failure: Low health causes the screen to redden and pulse, but you seem no less capable at fighting. Justified since the Space Marines tend to be Badass enough to resist pain and fight on until incapacitation due to extreme genetic modification and engineering, as well as years of training and conditioning.
Deadpan Snarker: Sergeant Sidonus; his "been there, done that, no problem" attitude and dry sense of humor makes him one of these.
Dead All Along: Inquisitor Drogan, before the Space Marines even arrived on the scene. One of the audio logs you can find is his death and possession by one of Nemeroth's agents.
Melta Guns, heat-based weapons utilizing sub-atomic agitation of the air, typically used for taking out tanks at close range, appears as a shotgun substitute (likely because the normal 40K Combat Shotguns would be insufficient against the enemies in the game and only the Scouts are allowed to use them in a Space Marine chapter).
The Lascannon is an 'extremely powerful version of the lasgun. It doesn't have quite the punch of the melta, but has a much longer range.
Deconstruction: Several audio logs take apart the Orks, who have long been the setting's comic relief, by throwing into stark relief just how horrifying a Blood Knight race whose only concern is fighting and killing really is. Suddenly, they're not the football hooligan aliens with a funny Funetik Aksent whose tech runs on Clap Your Hands If You Believe, they're brutal monsters who dismember everyone in their path and laugh while they do it.
The Space Marines, obviously, but that goes without saying in this franchise.
2nd Lt. Mira is perhaps a more unusual example. Her forces are outnumbered, cut off from support, dwindling quickly, facing down foes several times stronger than her and her soldiers, all while she bears a command burden well above her modest rank. Yet, she is never shown faltering, doubting, or even considering giving up the fight. She instantly mobilizes assets to assist the Ultramarines with whatever they need, is shown actively encouraging her soldiers not to despair, and they claim that she is responsible for why they have been able to hold out as long as they have.
Dirt Forcefield: While Titus will end up covered in blood after executing an ork or three dozen, it'll have faded off before the next battle.
Discontinuity Nod: Much of the conflict in the story is driven by a Plot Device which functions as a power source by drawing energy directly from the Warp. Similar devices were described in early editions of the setting, but the knowledge of their construction was the exclusive domain of the Squats.
Downloadable Content: A considerable amount. It mostly consists of new multiplayer Space Marine veteran or Chaos champion skins, from various Chapters or Legions, but there's also the "Chaos Invasion" addon which allows Chaos Marines for coop play, and "The Dreadnought", which introduces a new gametype with three maps where the top player on a team gets to control a mighty Dreadnought.
Drop the Hammer: The player may use Thunder Hammers at some points in the single-player campaign, and it is also available in multi-player. In single-player you can only use your Pistol or Bolter if you have one (and in multiplayer only the Pistol unless you have a perk that allows a Bolter), but since it's the strongest melee weapon, it's well worth it. Even more so when you have a Jump Pack, which restricts you to the same weapons anyway.
Averted, particularly with the Imperial Guardsmen. They were hard pressed against the Ork Waaagh! and almost certainly doomed before your arrival; and after you (quite literally if you so choose) hack your way through a huge mob of Orks closing in to push through their lines, most of the Guardsmen are very much in awe of Titus and his comrades. Some of the casualties in the bunker thank the God-Emperor that they were able to see a Space Marine before the end, and utter a prayer on your behalf. They also tend to kneel before you and address you as "My lord".
It's also averted from the Space Marines towards the Imperial guard. Titus shows nothing but respect and admiration for troops so willing to lay their life on the line to protect their planet, rather than the usual treatment of "Oh look, more Cannon Fodder." This attitude instantly wins Lieutenant Mira over.
Dynamic Entry: An insanely AWESOME example: in the final stage, Titus must cross a bridge being held by Chaos Marines on his way to face Nemeroth. The bridge is INFESTED with them, and you'll come to a part where there is basically no way to cross without getting killed... until a Space Marine droppod lands with an explosion amongst the Chaos Marines and Space Marines from the Ultramarines, Blood Ravens and Black Templars storm out and start slaughtering them. FOR THE EMPEROR!!
Finishing Move: Stunned enemies may be executed. Aside from obviously looking frakkin' awesome, it is the only way to restore health in the single-player outside of activating Fury (which requires causing a lot of damage to charge it up).
It can be averted in private multiplayer, however, as the host can enable friendly fire.
Foreshadowing: Leandros' establishing moments at the beginning of the game are questioning Captain Titus' combat strategies, as they are contradictory to those established in the Codex Astartes. He also shows absolutely no tolerance for anything involving the Warp. This is what eventually leads to Leandros reporting Titus to the Inquisition for supposed Warp taint.
Game-Breaking Bug: Due to clipping issues, Orks in Exterminatus mode sometimes fall out of the level, making it impossible for the Marines to kill them. Since every Ork in an attack wave has to die before the level progresses, this effectively renders the level Unwinnable.
Grimskull. While he possesses many of the typicalOrktraits, he's quite strategically intelligent, as recognized by the protagonists. His Ork horde is quite organized and he even ordered his Orks to take control of the planetary defense weapons to hold off incoming Imperial reinforcements note Typical Ork behaviour would simply be to dismantle and loot the defenses, as pointed out by your squadmates..
Genre Shift: Halfway through the game, the entire tone and gameplay style suddenly changes from a superheroic boyhood-fulfilment-fantasy to a War Is Hell horror game. See Shoo Out the Clowns below for more details.
Godzilla Threshold: Surprisingly averted. A Titan-producing Forge World falling into the hands of da Orkz sounds like a good reason to call down an Exterminatus, but the Imperium needs the facility just as much as Xenos does. So Plan A is to send the Ultramarines to recapture it (mostly) intact.
Gory Discretion Shot: One execution animation is to start to rip off a Nob's jaw. His entire head explodes, rather than actually ripping the jaw off. (Yes, this is the sort of game where showing someone's head exploding counts as a Gory Discretion Shot!) Otherwise averted.
Groin Attack: One of the execution moves with the chainsword starts with a strike between the legs that lasts for a couple of seconds.
Healing Potion: Averted... almost. There are only two methods of regenerating health in single player, and the easier method is executing something that can kill you right back (the other method is Fury... which also involves killing someone. Lots of someones). Even the regular Orks have to be stunned before they can be executed, not to mention that you can't move or dodge while Titus does all his fancy Chainsword-waving. But 'tis a Grim Dark universe when a mob of Gretchin (knee-high green scavenger psychopaths) or Renegade Militia (trained soldiers turned to worshiping the Chaos Gods) can be considered as walking Healing Potions due to the ease and speed they can be executed.
Homage: The battle between Titus and the partially Daemonized Nemeroth during free-fall seems to pay homage from the scene in the Ultramarines movie where a Daemon Prince plunges both itself and Captain Severus off a cliff. Unlike the movie, we get to see what happened, and unlike Severus, who lost and gets his body possessed by the Daemon Prince, Titus actually succeeds.
Hope Bringers: The Space Marines to the Imperial Guard. The first thing Lieutenant Mira does when she sees Titus's squad is to relax and thank the Emperor, and every time a battle between the Guard and Orkz is joined by the Space Marines, the Guard subsequently gets inspired and manages to win.
Hyperspace Arsenal: You can carry up to five weapons (counting the one currently in your hands), and while Astartes are more than strong enough to haul everything, one wonders where they keep it.
The execution for Ork Weirdboyz involves grabbing their staff, then impaling them through the abdomen with it.
Also how Sidonus is killed.
Injured Vulnerability: Executions, where you kill an enemy in the bloodiest way possible to regain health. The catch is that the enemy must be stunned, and stunning is a slower, no damage move, and tougher enemies require a combo chain ending in a stun. Fortunately averted with gretchin and rebel militia, which you basically Offhand Backhand to death.
Knight Templar: Surprisingly subverted, given the setting. Inquisitor Thrax is actually a fairly nice guy, and appears reluctant to charge Titus with heresy. He also agrees to only "investigate" Titus and let his unit go, which is pretty much the opposite of what a typical Inquisitor would do.
Granted, he noticed that Titus's wounds were inflicted by Chaos and asked Leandros if he was sure about the charge. It could just be that he didn't think that Titus was a heretic and Leandros was just over-reacting, so there was no need to get aggressive with a charge that he was positive wouldn't end badly.
Lampshade Hanging: One Guardsman, whilst trying to fix a Basilisk, complains that they're on a Forge World, but there are no Tech-Priests to be found. This is true, because there's not even one encounter with a Tech-Priest or any member of the Adeptus Mechanicus in the game (despite the Mechanicus having a large presence on Forge Worlds).
Guardsman: "Pass me the field manual! We're stuck on a bloody Forge World, and not a Tech-Priest in sight!"
Leitmotif: The game has several excellent ones, including some rousing battle drums to indicate encroaching battle. Probably the most memorable though is that of the Orkz, which is clearly (and hilariously) the tolling of a thousand vuvuzelas.
Lightning Bruiser: Assault Marines/Raptors use Jump Packs to quickly close in with a Ground Pound, stun enemies near the impact zone and then tear them apart with their close-quarter weapons.
Limit Break: The 'Fury' system in the single-player has a bar that fills up as you fight, allowing you to unleash a devastating Herd Hitting Attack on surrounding enemies in a melee, temporarily go into Bullet Time with ranged weaponry, regenerates your health, and allows you to perform executions at any time.
Ludicrous Gibs: Your default guns fire bullets that penetrate their target, then explode inside a second later. And that's just your default weapons. The Chunky Salsa Rule is in effect.
Mook Chivalry: Averted. Enemies in single-player and multiplayer alike won't hesitate to gang up on you.
Multi-Melee Master: There's a lot of melee weapons to choose from in the game. The Assault Marine/Raptor class uses them to great effect.
Multi-Ranged Master: There's lots of guns to choose from too. Used by Devastator Marines/Havocs and Tactical Marines/Chaos Marines in the multiplayer with a multitude of different guns to use - Tactical Marines/Chaos Marines even have a perk that allows them to carry another!
Mythology Gag: The maximum character level in multiplayer is 41, and in Annihilation mode, the first team to score 41 kills wins. Initially, it seems like a odd number to pick, but it makes a lot of funny sense when you realize that the 41st millennium is the setting of 40K.
Captain Titus blows an Ork ship up by landing on it with Jump Packs and turning one of its own guns at its bridge... and that's all before the title splash. By the way, he did all that with only a Bolt Pistol and a Combat Knife (granted, the Bolt Pistol is .75 caliber and the "knife" is more like a short sword).
He then tops that by single-handedly assaulting Nemeroth's stronghold, fighting his way through all of Nemeroth's servants, and then proceeding to punch Nemeroth to death, who is in the middle of turning into a Daemon Prince, while in freefall. He finishes Nemeroth off by crushing his head, then destroys the Power Source, causing a huge explosion. And Titus survives it without a scratch...which makes the Inquisition curious.
The Only One: Titus, Sidonus, and Leandros are sent into battle alone in that area of Graianote They're not the only Ultramarines squad in the theatre, but the others are operating elsewhere on the planet before they discover a surviving garrison of the Cadian 203rd, open up the path for the Guardsmen to receive reinforcements, and are themselves reinforced when the Liberation Fleet arrives, at which point they are no longer the only Space Marines in the area.
All plasma weapons can also suffer from overheating, though thankfully they don't explode and damage you like in the tabletop game.
In multiplayer the plasma cannon can explode and kill you if you charge it too long.
Overly Long Fighting Animation: The main problem with executions, which is also the reason why regular Regenerating Health is used for multi-player and the co-op "Exterminatus" mode. Enemies will still attack you while you're doing them, negating at least some of the health you gain from it. It takes even longer against elite enemies like the Nobs and the Chaos Space Marines, requiring some button-mashing (unless you're using a Thunder Hammer or are in Fury mode) to actually kill them, though you do get more health from it and will stun all the nearby Mooks.
Porting Disaster: The PC version is all but unplayable due to massive audio and framerate stuttering/lagging that will never be fixed due to THQ's bankruptcy.
Powered Armor: As any 40K fan would expect for the Space Marines. It provides a regenerating armor layer, which can be boosted with the Iron Halo (a plot-mandated upgrade in single-player, and a perk in multi-player).
Power Weapon: Power Axes and Power Swords, the latter of which is multiplayer-exclusive. Both work by sheathing the blade in an energy field, allowing it to cut through armor with ease. The Power Sword, which is simply a reskinned Chainsword so that it doesn't provide an unfair advantage, is unlocked by playing the twin stick shooter Warhammer 40000 Kill Team on consoles or if you had pre-ordered the Special Edition.
Not exactly an unfair advantage, but since the power sword doesn't make the same trademark growl as the chainsword, it's a bit stealthier (if less satisfying) in multiplayer, since you can hear a chainsword from across the map.
Stun an Ork Nob or a Chaos Marine. See that big tempting "Execute" icon floating over him? If you try to execute them without having 'Fury' mode on or without a Thunder Hammer, you'll have to rapidly mash the shoot button to overpower them. Otherwise they'll pick you up, slam you to the ground, and attempt a Finishing Stomp (Chaos Marines just knock you to the ground), which drains up to half your health.
Just look at the page image. You play as an seven and a half foot tall Super Soldier encased in Powered Armor that only enhances their size and wield exotic weaponry to match their defenses. Take Cover is intentionally averted to encourage getting into your opponents' face, which you will soon find to be full of blood. You will likely kill scores of Orks throughout the game, with whatever methods you choose.
Late in the game, Captain Titus' Valkyrie is taken down by a Stormboy's body clogging up an engine. Titus' response is to effortlessly jump from the crashing transport and roll as he lands.
Just to reiterate, the only way to heal yourself is either brutally execute a stunned foe or to kill enough enemies to fly into a berserk rage. Either way, you're going to be covered in blood from head to toe.
Real Is Brown: Played with. The developers made it clear they wanted the game to be bright and colorful, and they pretty much pulled it off as far as combat and character designs are concerned (the Ultramarines wear bright blue and gold armor, for example). The environments, however, tend to be brown or grey (you're on a Forge World, after all), and the regular Imperials tend to wear rather drab uniforms.
Justified: Guardsmen dress for camouflage, while Space Marines dress to impress. You are not supposed to see Guardsmen coming; Space Marines want you to see them coming so you can piss your pants.
CAMOUFLAGE IS THE COLOR OF COWARDICE.
"The Reason You Suck" Speech: Titus delivers a short one to Leandros at the end, telling him that his blind adherence to the letter of the Codex Astartes is a failing on his part.
Although it's somewhat funny to hear this from an Ultramarine, since of all the Chapters, "blind adherence to the Codex" describes their hat best. Although they're not thoughtless automatons without capability for tactical flexibility, of course, so it's not really a conflict with the fluff.note (Titus in particular specifically calls out that respecting the Codex should be a given, it is leaning to creatively apply those lessons to life on the battlefield where the challenge lies) Still, it is pretty ironic.
Reconstruction: Arguably one for the Ultramarines. These are neither the "nearly useless without a Codex Astartes solution" portrayal, nor are they the Canon Sues of Matt Ward. The game instead strikes somewhat of a balance: the Ultramarines aren't invincible, but they're also willing to throw out the manual if the situation calls for it (Titus specifically points out in an early cutscene that Leandros needs to think for himself instead of blindly obeying the Codex). It also helps that the story called for exactly the scenario the Ultramarines excel at: being generic action heroes.
Removable Turret Gun: Autocannons, Heavy Bolters, and Plasma Cannons can all be taken from their tripods and carried around; you can't run or do a dodge roll while carrying them, but the amount of firepower you get in exchange is well worth it.
RPG Elements: Multi-player includes a level and challenge system like Rainbow Six Vegas and Call of Duty 4: Modern Warfare (and every other main entry in the series thereafter) to unlock more perks, weapons and armour pieces. Classes are customizable, but are limited to three classes of degrees of ranged and close-combat effectiveness - Devastator Marines/Havocs for the former, Assault Marines/Raptors for the latter, and Tactical Marines/Chaos Marines in the middle.
Scenery Porn: The inside of Manufactorum Ajakis is beautiful, even more so when you catch a glimpse of the Titan Invictus. Also overlaps with:
Scenery Gorn: Graia is very torn up by the time you get there, though it does make for some pretty awesome vistas, such as when you first touch down and walk through the wreckage, eventually coming to a long avenue with an enormous and miraculously still intact statue depicting a cloaked figure with a spiked ring around their head at the far end.
Lampshaded at one point when the squad is approaching an absolutely massive suspension bridge, which looks like a cross between the Golden Gate and Brooklyn Bridges, and they immediately start extolling the virtues of the Adeptus Mechanicus for being able to build such a thing.
Sequel Hook: The game ends with Titus willingly allowing himself to be taken away by the Inquisition, with Titus promising he will get to the bottom of his ability to resist the Warp.
However, it's been announced that there won't be a sequel, as there's 'no room' for it with the upcoming MMO, Dark Millennium.
Serrated Blade of Pain: In multiplayer, Tactical Marines/Chaos Marines can get a perk that upgrades their regular Combat Knives to these. They deal additional damage.
Shockwave Stomp: A defensive ability available to Devastators/Havocs in Multiplayer, useful for stunning and disorienting enemies. Perks can increase the speed of the animation, and/or the range and damage.
Shoulders of Doom: Used with other adaptations of 40K's Space Marines, and this one is no different. The shoulders, however, are surprisingly articulate, and Titus and the other Space Marines seem to have a full range of arm movement.
Bolts don't explode until a split second after they make impact.
The Adeptus Mechanicus iconography is exact.
Oaths of moment are visible on the armor of the Space Marines.
The Stalker and Kraken Bolters are taken straight from the 5th edition Space Marine Codex.
Shoo Out the Clowns: When the lovably-goofy and Laughably Evil Orks are the primary antagonists of the game, Space Marine is a rip-roaring swashbuckling boyhood-fantasy fulfilling romp where superheroic One-Man Army Tropes are taken to their ludicrous logical conclusions. When the Orks retreat and let the Chaos Daemons and Marines take central stage, on the other hand, the game becomes a substantially darker and bleaker Saving Private Ryan meets Call of Duty style war-game.
Slashed Throat: The execution for Bloodletters, if you have a Chainsword, involves grabbing the Bloodletter from behind, and slitting its throat with the Chainsword. Sidonus demonstrates in a cutscene, and is killed by Nemeroth right afterwards.
Most (if not all) Chaos Marines tend to have these, especially Nemeroth.
In the multiplayer armor customizer, one set of armor is literally called "spiked".
The main way to distinguish Havoc Marines from Tactical Chaos Marines is that Havocs have a great deal more.
Standard FPS Guns: The only ones not present are the flame thrower (the melta gun is more of a shotgun stand in, though, it perhaps counts as both) and the rocket launcher.
Rocket launchers aren't available to the player character or in multiplayer; they are available to orks.
Sword and Gun: Used by Captain Titus in single-player and the Assault Marine/Raptor class in the multiplayer, when holding a Bolt or Plasma Pistol. Wearing a Jump Pack or wielding a Thunder Hammer in single-player and the True Grit perk in multi-player allows them to wield a rifle-size Bolter in place of their Pistol, one-handed!
True Grit is a standard feature of the Gray Knights Chapter: The Marine must be wearing regular Power Armor (not Terminator) which allows them to use their WRIST MOUNT STORM BOLTER in Close Combat as an extra Close Combat Weapon.
Titus may pull out his Chain Sword or Power Axe with any weapon unless he's torn a turret off its stand.
The Musketeer: The game is intended to allow quick swapping and viability of both close-combat and ranged weapons alike. The intended use of the Tactical Marines/Chaos Marines within multi-player, skilled with both a ranged weapon and a Combat Knife.
Trailers Always Spoil: Some trailers have shown us in-game footage that we were probably not supposed to see. Examples include Inquisitor Drogan casually walking past some Bloodletters, Nemeroth turning into a Daemon Prince and Captain Titus killing Warboss Grimskull.
Also, the presence of Chaos, which doesn't occur until Mission 11.
Triage Tyrant: One set of logs is a recording of various conversations between a Medicae with no combat wound experience and a nurse who had plenty. As the logs go on, the amount of treatment given to the wounded is reduced to the bare minimum needed to keep them alive, then locking the doors to the clinic because they no longer have room for any more patients. Ultimately, they have to Mercy Kill all of their patients before the Orks arrive.
Ungrateful Bastard: Leandros is one. He and many of his battle-brothers would have been killed if not for Titus killing Nemeroth, but he sends Titus to the mercy of the Inquisition anyway.
Walk It Off: Present - Justified by a Space Marine's physiology, with their Larraman's Organ causing non-fatal wounds to clot and scar quickly in addition to their lengthy and intense training allowing them to carry on long after ordinary humans would be incapacitated. The game is intended to largely subvert it in the single-player campaign, since performing a close-range execution will restore health, so if there's enemies, you don't have to wait! Get cleansing.
Weaponized Exhaust: One of the options that can be unlocked for Assault Marines/Chaos Raptors in multiplayer is causing damage with the jump pack's exhaust on takeoff.
What the Hell, Hero?: At the end, when Leandros defends his decision to accuse Titus of heresy by insisting that he was acting in accordance to the Codex Astartes, Titus tells him that that is indeed true, and that he is a good example of a "model" Imperial citizen... but then sharply tells him that he allowed the Codex to fully control his actions rather than use it as a rulebook or a set of guidelines, and thus fails as a Space Marine.
With This Herring: Titus starts the game by jumping off a dropship with a Jump Pack (which he disposes of once he lands), a Combat Knife and a Bolt Pistol. Considering the loadout available to an Ultramarine Captain, he might as well have jumped in naked. There's basically no reason for him not to bring a Thunder Hammer and a Storm Bolter right off the bat - except game balance, of course.
