The Imperium wans to attack from the south side (behind the battlewagons, hurr, rear armor, hurr!) But Chaos and the Orks are like, nuh-uh, we will use deployment denial and now you need to come in from a different side. The Imperium chooses the North side and shrug, claiming they'll kill everything anyway.
The Imperium's first move is to reveal the Immortal Host's strategem - Confusion! The Lootas are pulled out of their cover and placed on open catwalks, while the Oblits are shoved closer to the Imperium deployment zone where the 1st Allied Mechanius plans to...wait for it...
obliterate them.
Now to see how we do for Firestorm...
...we'll accept that.
Marcus Scipio working to drop some blasts on the Battlewagons, but the scatters serve him poorly, and besides a lucky shake that killed a Cultist very little damage is done.
Better damage is done to the Lootas as the catwalk is engulfed in flame and Orks are sent screaming and burning as the leap off the walkways to their deaths.
More blasts crash into the Tankbusta bunker, killing almost a third of the squad before they've even had a chance to smash a vehicle.
The Immortal Host Sternguard leads the way as they drop down amidst the Plague Tower holding field and head towards the primary tower - their job is to overcome the stern defense and secure the entire left flank.
To support their melta packing brethren, some more Sternguard with plasma weaponry drop in.
The forces of The Immortal Host ready themselves for glory.
Not liking the lay of the land at all, Captain Paget leads his forces into battle, his squad and the horde of Conscripts prepare to lay down suppressing fire on the Obliterators.
First rank fire, second rank fire...EVERYBODY FIRE! I want those things dead!
Bran Lachlann and Emerald Wing drop down to support the
IG.
Amethyst Wing drops down as well.
Though they are rather distant from the rest of the army...guess we'll just take out these battlewagons then.
The Stormtroopers drop in nearby, their goal is to finish off the Lootas and then form a firebase to support the Raven Guard.
Shadow Captain Lachlann considers the nearby Chaos Sorcerer and the Oblits a primary threat.
The Immortal Host trot forward towards the tower, seeking cover but finding little.
One of the Immortal Host squads runs afoul of a Krak trap, and lose more than half their number before they even hit the ground of the battle field - both of their melta gunners are lost - the tower siege just got more complicated...
The dark tower looks ominous - but the
IG have a few tricks of their own to help out, they unleash a Teleport Barrage, and fuse 3 Obliterators and the Sorcerer with the very walls of the bastion - suddenly the unassailable fortress looks more attainable.
The
IG advance from the left side, looking to claim the objectives there via weight of bodies. Meanwhile surgical marine strikes hope to dismantle the defenses.
A cunning plan, but can it work?
The view of the defenders as the host approaches - like tiny, purple, insects. Papa Nurgle approves!
Prepare lasrifles, fire!
The Stormtroopers pick apart the last of the Lootas - the Ork firing line has been severed.
Now it's up to the Raven Guard Amethyst wing to deal with the Ork reserves...
Like silent death the Raven Guard spring forward, readying a melta bomb and grenades as they assault one of the Ork warmachines.
The Oblits weather the
IG shooting as though laser bolts are just a soft summer rain - realizing the Oblits could decimate the infantry forces if left unmolested Shadow Captain Lachlann springs forward with his squad to engage them in hand to hand combat.
"In the Emperor's name, you shall fall, scion of Chaos!"
Bran and the Chaos sorcerer face off in a deadly duel as their units battle.
Their Captain is unable to wound the sorcerer, and his squads weapons bounce off the Oblit's armor, but the slowly stalking death machines push on, felling two battle brothers as they fight to reclaim the walkway and hold the Early Warning System radar.
Amethyst Wing meets with more success, and destroys the battlewagon - now they just need to contend with the angry survivors of the explosion...
With the aid of their comm relays...all of the Chaos and Ork reserves arrive.
HAHAHAHA! DAKKA-DAKKA-DAKKA!
With a horrendous roar of jet engines, the Ork air force appears in deadly
dives controlled falls and move to target the Immortal Host 2nd company elements.
Chaos bikes also arrive, ready to bring their flamers to bear on the Raven Guard.
"Excellent with the Oblits tied up we can send the Conscripts forward while we hold the rear lines, and..." Captain Paget's hopes are dashed as two Ork Big Meks, and a horde of Kommandos burst out of hidden holes they had buried themselves in,
"SURPRISE ATTACK!" They howl at the top of their lungs as they lumber forward with flamers.
Dark Chaos magic is also brought to bear, enfeebling Raven Guard and Immortal host units.
"Dis is Blu Thunda reportin' in!" Shouted Gorbag out the window as he passed over the Big Meks, "whot's the plan!?!"
When they didn't answer...not that he was certain he could have heard them even if they did...not that he was certain they had heard him...aw, zoggit, let's just shoot up the beakie-boyz, WAAAAAGH!
Photo proof for Bruce that I was right about him placing that Dakkajet illegally close to my army - neener-neener
More Chaos bikes arrive, readying their melta gun to deal with one of the Sentinels.
We are so boned, though Captain Paget to himself. Now I need to figure out a way to get out of here...
Chaos Cultists hold their bastion, but don't bother to come out and face the Stormtroopers.
"Hey, there is stuff to stomp out there, an' according to the Co-dexy, when dere's stuff ta stomp, we stompz it!"
The Ultraboyz roar out of their battlewagon in picture perfect parade formation and shout invectives to Nob-but Orky-man as they prepare to bring battle to the Raven Guard.
They open fire and drop four Raven Guard!
The Chaos flamers finish the job, Amethyst Wing is down.
The last Oblit from the prime Bastion lumbers out of the mangled mess of walls and Oblit parts to bring some flamer love to the Stormtroopers.
Things go poorly for the Stormtroopers, and the Orks in the crater finish off the last two survivors. The southwest quadrant is in firm, and very green, hands once again.
The withering firepower of the Dakkajets cuts apart the Immortal Host as they move forward with dogged determination to reach their objective.
The Kommandos and Big Meks unleash a torrent of urnas into the massed guard lines.
With predictable results.
As the Sentinel is blasted apart by Chaos meltaguns, Shadow Captain Lachlann withdraws from combat with the Oblits, his men having been blunted in trying to deal with the heavy armor and now with the infantry line under further danger, Lachlann prepares to give battle to the Big Meks and Kommandos.
Ogryn, Ogryn, Ogryn!
Commissar Steele and his Ogryn squad rush forward to secure the line (which is possibly a fething line, but Commissar Steele would consider it rude to point that out)
Due to a Perils of the Warp situation the Ratlings are deposited not on their handy planned sniper location, but rather right in front of the Ultraboyz.
"Look to the skies, brother."
The Immortal Host drops down on the Skyshield landing pad and targets the Chaos Bikers.
The Raven Guard moves up as the Ogryn open up with their Ripper Guns on the Kommandos.
A Chaos biker is blasted to shreds.
The weakened vanguard of the Host continues to doggedly try to shoot apart the Oblits holding the bastion.
Meanwhile, another squad decide to say hello to some Chaos Cultists by shoving grenades inside the building - it ends poorly for Chaos.
The southwest secure, the Orks and Chaos now just have to deal with the rest of the battlefield.
Obligatory Thor crotch shot

Now our collection is complete.
"Nevermore!"
The Assault Sarge engages a Big Mek in solo combat, shredding him apart with his lightning claws.
The rest of the Kommanods, Snikrot, and the other Big Mek fare little better, being sawed apart by Lachlann's men.
The Immortal Host hold the first secure objective, one of the Bastions has been cleansed of Chaos forces.
The melta Chaos bikes are wiped out by the Immortal Host as well.
The Imperial access route secured, now it's time to resume the push inward.
A Dakka Jet howls towards the Raven Guard, intent to avenge the fallen Kommando force.
The Ratlings killed off some Tankbustas - but now, setting the gearshift to 'mulch' the Orks let their displeasure be known.
The life of a Ratling is not an easy one...
The Ork horde and the Chaos Bikers move to continue the Chaos push and prevent further gains by the Imperium.
Closing in on the Immortal Host forces, Chaos and the Orks begin to dismantle their assault.
With fire.
The Green tide spreads outward, ready to drown everything in its path.
Another Perils victim - the Assault Termies were consigned to a far corner and are having to footslog forward.
The damage done to the Immortal Host vanguard by the Dakka jets and also how the one battle fortress is holding this flank is very clear here.
Chaos contains the advance and starts crushing it as they shove back.
The Oblits hold the high ground, and with the Dakka Jets have turned the surface of the spaceport into a killing field.
The Dakka Jet cuts apart most of Emerald Wing, leaving only the Sargent and Lachlann.
Lachlann is undeterred and leads his last upright battle brother onto the rooftops - it was time to finish off the Oblits and secure the approach into the rest of the spaceport.
The assault squad of the Host moves in to help as well.
"Up and to them, my lads, let's give them the cold steel!"
"Yar, and krunch them too!"
Commissar Steele and the Ogryn Bone'ead move in as well. The Oblits have been tough to deal with, but if brute force doesn't work, you're probably not using enough.
The Immortal Host enters the tower, and begins a brutal war of grenades, flamers, and ambush as they fight to clear the Oblits from the central defense point. Finally the Chaos guns begin to fall silent as they dismantle the computer operated firing systems.
The lone Oblit is still trading shots with the tattered Immortal Host forces on the ground level near the tower.
Battered and bloody, the Immortal Host lays claim to firing positions and began unleashing supporting fire into the Spaceport - now the Imperium has fire support!
"You are a creature of Chaos, and I intend to kill you in unpleasant ways!"
"Bring it, Corpse worshipper!"
Commissar Steele challenges the Chaos Sorcerer as their men clash.
Chaos might be a bit outnumbered...
Both Lachlann and one of the Immortal Host perform jump-pack assisted flying knees to the Oblit's faces, felling the agents of Chaos before they can even begin to prepare themselves for the attack.
Meanwhile, Steele bodyslams the sorcerer and smashes his skull in.
"Sic, Semper, Hereticus!"
Librarian Darius of the Immortal Host used his jump pack to keep him where the fighting was thickest. Still, he seemed intently to be searching amongst the fallen Sorcerers for something, as though it were more important to him than the battle's outcome.
He still led the assault on the Chaos Bikers, cleansing the battlefield of their taint.
As the Immortal Host secured the rearguard, the Ogryn and Raven Guard pressed their advantage.
The Ultraboyz were eager to answer their challenge.
"The Co-dexy sayz when stuff gets bad, stand inna central location firing in all directions and striking cool poses! Waaagh, dakka-dakka-dakka!"
The two waves of Imperial and Ork reserves rush inexorably towards each other...
The Immortal Host rearguard is decimated as the Weirdboy crackles with power and hurls bolts of energy across the board to blast them to pieces.
The Dakka Jets return.
One of the blasting apart a couple of Ogryns and their Bone'ead.
The other decimates the Conscripts, killing almost all of them in one wild strafing run.
Commissar Steele politely reminds them that he would be allowed by his orders to kill them all if they ran...so they choose to stay.
The Conscripts more to the satellite array to claim it for The Imperium while the Sentinel attempts to fight off the Dakka Jets with bursts of auto-cannon fire.
So close, yet so far - the Termies continue their slow walk.
The tattered vanguard of the Host finally claims the tall tower - the powers of Chaos in the north east quadrant has been sundered, and now is firmly held by the Host.
The lone Oblit still stalks the battlefield though, attacking any Immortal Host it spots.
Orks also still resist and try to defend the final objectives.
Orks fire into the onrushing Ogryns to little real effect.
Librarian Darius hunts down the final Oblit, securing the quadrant for the Imperium forces.
The Sentinel does little to the Dakka Jets.
We are relevant!
Chaos holds this comm relay, a bastion beyond, and the access alley way is filled with the Ultraboyz.
"Stay with me, lads," Commissar Steele leads the Ogryn's forward, "now kick them in their face!"
Lachlann and the Ogryns smash into the orkish lines.
"We're losin' boyz, quick, write a new Co-dexy instead of trying ta defend da Palace!"
Commissar Steele ignores this blasphemous talk and instead wades through the Ork lines, tearing them apart and breaking the back of the final Ork defense.
The Immortal Host holds the high tower.
Conscripts secure the vital Array.
Though the Orks still rule the skies in their Dakka Jets, the Cultists are no match against the Ogryn and Raven Guard assaults.
With a few rude gestures out the windows, Blu Thunda leads the withdrawl. The Imperium holds the Spaceport - the liberation of Saios has begun!
