Also, been reading the Apocalypse Expansion book. Plenty of great feats for tech and such:
The Imperium boasts the most powerful military force the galaxy has ever seen. Indeed, the Imperial Guard alone is the largest and most diverse body in existence, yet forms only a single component in the Imperium's unstoppable war machine. Alongside the countless regiments of disciplined soldiery and tank companies of the Imperial Guard, super-heavy war machines of enormous scale lay down withering salvoes of heavy ordnance even as they crush the broken bodies of the enemy beneath their tracks.
Alongside the Imperial Guard fight the Space Marines; elite super soldiers and the champions of Humanity, each a genetically engineered warrior equipped with the finest wargear and capable of defeating many times his number in battle. Towering above all others stride the unstoppable Titans of the Adeptus Mechanicus, mighty God-machines that wield firepower of such magnitude that they can level entire cites. Yet even these colossal engines of war are dwarfed by the battleships of the Imperial Navy. These star-faring warships, many miles in length, relentlessly pound the enemies of the Imperium with murderous bombardments from low orbit in support of their forces on the ground. As their warships rain death from above, the Imperial Navy's fleet of aircraft bomb and strafe the enemy hordes from the skies.
There are other, more clandestine, organisations secretly ensconced within the Imperium's infrastructure; though their work is more subtle, they are no less dedicated in their defence of Mankind. Chief of these is the Inquisition - an enigmatic council of powerful agents and interrogators with the authority to condemn billions to death or whole worlds to destruction. At the behest of the Inquisition, the deadly killers of the Officio Assassinorum deliver silent death to sever the command structure of those who would oppose the Emperor's might. Against the Daemon and the alien, the Imperium will deploy the Grey Knights or the Deathwatch - elite Space Marines even amongst others of their kind, and masters of hunting their chosen quarry.
Each wing of the Imperium's vast military organisation is a formidable fighting force in its own right, capable of defeating almost any foe with faith, overwhelming firepower, skill at arms or sheer weight of numbers.
Description of the Imperium of Man's military force.
Super Heavy Vehicles
"From the lumbering Baneblade tanks of the Imperial Guard to the forbidding Tesseract Vault of the Necrons, all of the war engines that fall into this category are huge armour-clad constructions that each carry enough firepower to vaporise, smash or incinerate an entire army."
War machines that can vaporize entire armies.
"The Banesword is an adaptation of the venerated Shadow sword design, exchanging the Titan-killing cannon of its predecessor for the fortress-pounding fury of a quake cannon. The resulting combination of devastating siege gun and nigh-impenetrable armour is considered by many to be the last word in Imperial siegecraft."
Tank with Titan-busting cannons.
"The thousand-year Siege of Ordana saw a new super-heavy tank design pressed into Imperial service - the Doomhammer. A Doomhammer's magma cannon is closely modelled on the volcano cannon employed by the famous Shadow sword design. While it has a reduced range when compared to its larger cousin, the magma cannon is still able to marshal a Titan-killing blast of epic proportions."
Again.
"The Shadow sword mounts the largest and most powerful primary weapon in the arsenals of Mankind - the dreaded volcano cannon. This awesome weapon can cripple the largest war engines with a single shot. Nothing short of the most powerful energy shields can hope to stop a direct hit from a volcano cannon - no amount of armour or cover can offer protection from it. Throughout the history of the Imperium, Shadow sword tanks have proven to be the natural enemy of Titans of all classes and sizes. The Shadowsword lies in aguided volcano cannon, delivering the killing blow with a single precise shot aimed at one of the behemoth's weak points."
Shadowswords can destroy all classes of Titans.
"The Hellhammer is built around the same STC chassis as the Bane blade, but optimised for war in the city streets of the Imperium. Its armament favours shorter-range firepower, allowing the Hellhammer to move forward in support of infantry in urban areas and other dense terrain. The distinctive feature of the Hellhammer is its much shorter main cannon. This is equipped with heavy-gauge suppressors, allowing it to fire extremely high calibre shells without breaking itself apart with the recoil. These shells have an unstable sub-atomic charqe at their core, enablinq them to smash apart enemy vehicles, heavily armoured troops and fortifications with each shot."
Sub-atomic tank cannon.
"Psyker Battle Squads are usually made up ofpsykers that have yet to complete their training. However, sometimes more experience is needed, and a Primaris Psyker will be ordered to combine his power with that of a group of Sanctioned Psykers. The fusion of their psychic might allows them to unleash devastatingly effective attacks, and can even alter the fabric of time itself."
"A Sanctioned Psyker Battle Elite can combine their powers to create a disturbance in the fabric of space, causing repetitions and negations of the time stream."
Sanctioned Psyker squads can manipulate the fabric of space and time.
"A Space Marine Chapter includes only a handful of Librarians. Because of this, it is rare indeed for two or more Librarians to take part in the same battle, and only the most dire peril will require the presence of enough Librarians to form a Psychic Choir . Such a formation is called a Librarius, and it is able to annihilate a portion of reality with a monstrous attack known as the Force Vortex. By combining their mental powers, the Librarians are capable of creating a maelstrom of destructive psychic energy that will destroy anything it touches. Such an attack is never undertaken lightly, for should the Librarius lose control of the Force Vortex, it has the power to ravage an entire world."
Force Vortex
"The Librarius creates a globe of coruscating psychic energy that tears apart the molecular bonds of anything it touches."
A psychic choir of Space Marine Librarians can ravage an entire planet on a molecular level by summoning a Force Vortex.
"The Purifiers seldom fight as a single formation. All Grey Knights are rare, but Purifiers are doubly so, and their talents must be applied sparingly across the breadth of the war-torn Imperium. However, should circumstances prove dire enough, the Castellan of the Order sends word to his Brother-Purifiers that the Brothers of the Flame must be gathered. By focusing their psychic might, the Purifiers can summon vast constructs of living fire to consume the foe. Whilst the holy flames of a single Purifier can incinerate tightly-knit groups of enemies, their combined power is preceeded by a bow wave of towering azure flames that can sweep a battlefront clean of any taint of corruption."
Grey Knight Purifier squads can wipe an entire battlefield clean of their enemies.
"When a Deff Dread just isn't stompy, shooty or killy enough, a Big Mekfeels the urge to build a Stompa. Capable of laying waste to entire armies, a Stompa is a walking, shooting, roaring idol ofGork (or possibly Mark) that's just spoiling for afight. Especially large Stompas are sometimes called Gargants by the Orks. Each has a crew of Orks within its hulking frame, quite often three or four Meks (usually the very ones that collaborated on the towering machine's construction), and dozens of Grot riggers, runners, lookouts and assistants. A Stompa usually mounts two or three enormous guns for laying down some serious dakka, as wekk as a mega-choppa; usually some form of oversized power klaw or whirring chainblade, perfect for chewing up enemy tanks and Titans."
Ork Stompas can destroy Titans.
Eldritch Tempest
Eldar Psykers on board orbiting spaceships manipulate the planet's atmospherics, unleashing a raging energy storm on the surface below.
Eldar Psykers create planetary energy storms by manipulating the atmosphere.
"The Phantom Titan is the largest of the Eldar Titans. Tall, slender and graceful for all of its colossal size, it is agile when compared to the lumbering behemoths of the Imperium. Each of these mighty Titans is the pinnacle of Eldar warcraft, built around a powerful psychic wraithbone core which permits the spirits contained within to flow freely through the Titan to guide the machine and its steersman pilot. The Phantom carries some of the Eldar's largest and deadliest weaponry, enormous pulsars and distortion cannons able to sunder the mightiest fortifications their foes can devise. War machines of such size are reserved for the heaviest of fighting when the Eldar wish to wreak terrible destruction upon their enemies."
Eldar equivalent of Titans, can destroy the mightiest of fortifications with single cannon blasts.
"All Eldar Titans are agile and graceful, but the Revenant moves with a swiftness and smoothness that beggars belief This lithe Titan mounts powerful jump jets on its broad shoulders and narrow waist, allowing it to move in a series of drifting leaps. Despite its uncanny speed, the Revenant's primary defence is the image-distorting holo-fields that project from its rear wing. Yet it is the Revenant's offensive capability that makes it so feared. Its standard armament - the high-yield laser weapons known as pulsars - are capable of crippling an enemy Titan at long range, though they sometimes mount sonic lances theat literally shake their targets apart. The hunting skills of each steersman pilot are further enhanced by the spirits within the Titan's wraithbone core."
Eldar Revenant Titans are incredibly fast and agile, capable of blitzing other war-machines of its size, and also carries enough firepower to cripple Titans from a distance with single shots.
"Each Fire Prism grav-tank is a graceful predator in its own right. When the fury of its prism cannon is focused through the power crystals of others of its kind, however, it has the power to fire a laser beam of extreme and devastating force. It is said that should a Sunstorm Squadron be of sufficient size, it could scar the surface of a distant moon with its firepower. Squadrons of Fire Prisms take their name from the legendary Sunstorm called down by the father of all Eldar gods, Asuryan, who rearranged the suns themselves so that their constellations heralded a time of galactic ill omen. With the speed of thought, Asuryan then harnessed the power of the outraged stars he had controlled, and with a mighty barrage of solar flares he destroyed his foes outright."
Eldar Sunstorm Fire Prisms Squadrons can scar the surface of distant moons with their firepower. Also a very neat piece of Eldar Mythology with Asuryan.
"he strike forces ofCommorraghfield elite Ravager crews to locate and neutralise enemy Titans ahead of the main assault. These aerial hunting packs employ a technique called 'shadow dancing' to preserve themselves from the worst of incoming fire, flying perilously close to the ground, skirting between trees and using the silouettes of enemy vehicles to mask their approach. Once the pack has closed to weapons range, the lead Ravager triggers its shadow ray. This is an aetheric lance that probes the prey's shields, creating the smallest of breaches in its defences. The weakness is so minute that the victims remain unaware of its existence until the Ravagers fire pinpoint pulses of darklight energy into the breach, detonating their chosen target in a spectacular fireball."
Though they lack in direct firepower, Dark Eldar Ravager Squads can take down Titans through speed, stealth, and precision.
"Hive fleets typically attack in waves, each comprised of millions of biological horrors. Such is their number that to stand against them is usually as futile as trying to hold back the sea. Billions of gaunts are disgorged from a rain of mycetic spores that falls upon each prey planet, the expenditure of countless Tyranid lives a mere precursor to the greater onslaught. Many xenologists believe that the more common types of gaunt are employed primarily to exhaust enemy munitions, for if they are not killed as they rush closer, they will overwhelm gun lines and clog trenches in a living wave of stabbing, biting aliens. Running out of ammunition in the face of such an onslaught is sure to leave even the stronqest battle line easy prey for the assault to come."
The sheer size of single Tyranid swarms, composed of millions and billions of separate Tyranids.
"The Hierophant bio-titan towers over the battlefield, bristling with spines, tendrils and symbiote weapons. Comparable in size and power to the God-machines of the Titan Legions, the Hierophant is found at the forefront of a Tyranid heavy assault wave, shrugging off enemy heavy weapons fire and reducing swathes of the foe to toxic soup with its bio-cannons. The bio-titan's defences are many; its iron-hard carapace is bolstered by a crackling Warp shield, it has the ability to quickly reknit damaged tissue, and its underbelly is covered with living ropes of sinew that maim anything within reach. The Hierophant also constantly exudes a cloud of highly toxic spores from vents in its armour plates that choke and burn any prey orqanisms foolish enouqh to qet close ."
Tyranid Bio-Titans. It's just like Titans, but made of flesh, sentient, and deadlier.
"A Living Fortress is a rippling mass of rock-hard chitin and serrated claws that advances unstoppably towards the enemy line. Tyrant Guard are bred specifically to soak up enemy firepower, none more so than those who form the walls of the fortress itself. Even the Hive Tyrants they guard and the Hive Guard that afford them ranged firepower have specially reinforced chitin plates. Should its preternaturally sharp senses detect an incoming threat, the Living Fortress swiftly locks its chitin plates together and hunkers down, becoming a bastion of foot-thick carapace. Likened by the Eldar and the Imperials alike to a walking bunker, a Living Fortress is such a resilient threat that nothing short of a direct hit from a Titan's primary weapon or a Vortex grenade can dispose of it for good."
Tyranid Living Fortresses are so durable that nothing short of a Titan's primary weapon can put it down.
