The Empire continued to Attack the Tyranids as the Latter had made A Bunch of Deadly weapons and began using them on them! They had Biological Guns that shoot acid, Bullets that unleashed Flesh eating worms on someone, and even Grenades that Unleash Tentacles to rip people apart!

The Imperial Troops were being Pinned down being Constant Waves of Deadly Tyranid's and the only things that stood A Chance in defending against their attacks are the Heavily Armored Troops and the Droids since they can't consume the Latters Biomass!

Clone Commander: Go! Go! Go! Go!

The Commander kept Firing dozens of more Blaster Bolts into A Tyranid Killing it but 3 more surrounded him and Began tearing him apart, before he was eaten alive A Marine Killed them all and rescued him!

Clone Commander: T-Thanks...

Marine: No Problem, Us Battle Brothers gotta stick together, But Look on the bright Side. You'll get some new Shiny Legs. Ha!

Clone Commander: Y-Yeah, Good...

Super Tactical Droid: The Favor of Battle is Shifting. Running Calculations............ Chances of winning are slowly shiting to them. Our chances are now 50.2%. Need to call in Reinforcements to Rectify this.

He then contacted you.

Y/n: What is it?

Super Tactical Droid: The Forces of Invasive Aliens had grown too Great. We request reinforcements.

Y/n: Right, I Guessed So. I am coming with some Reinforcements. Just give me A Moment.

Just then They all heard A Noise coming up from Above...

Just then Hundreds of LAAT Gunships fell from the Sky and Began dropping off the second ever Legion of These New Space Marines, these ones dressed up in white and Red!

These ones were built to be Mobile Hunters, they were Known as the white Scars!

White Scars: FOR THE EMPEROR!!!

They all then Began Charging in with all of the Hover Bikes, walkers, Tanks, and Mechs they can and Began wiping out every Tyranid they came across, even the bigger ones were overwhlemed by sheer Numbers!

Y/n: You Okay?

Super Tactical Droids: Yes, I am but some Marines had been Critically Injured.

Y/n: Ha! They can be Become Dreadnoughts then! To them it's the Greatest Honor!

The Tyranids despite their constant Output of waves of their own Kind were Pushed back to their Nest as they contonued to try to make more of themselves with the Bio Mass they had gathered during the fight, but it was Pointless as Bombers were flying overhead!

Y-Wing Bombers

They dropped their Payload of heavy Bunker Busting Bombs on the Nest destoryering every Tyranid that was there, leaving nothing but dead Bodies Left!

As everyone Cheered, as You were left thinking about what Happened, as Ashoka arrived By Corvette to see what Happened.

Ahsoka: Is everything Okay?

Y/n: Yes.

Ahsoka: Then what's with the Face?

Y/n: For something this dangerous to appear, they must not come from this Galaxy.

Ahsoka: Which means?

Y/n: This is Just A Spearhead force meant to take A Small Planet on the rim of the Galaxy.

Ahsoka: So What do we do?

Y/n: We Just wait until they come back with more. Something tells me they already knew they Lost this Battle wherever they came from. (Thoughts) Oh Crap Not Tyranids! Their Just the worst thing since The Black Plague! Their Like All the worst Animals of Australia combined with A Xenomorph Makeover! I Hate to see those things again!

Of course they would return and in Greater Numbers so all you could now is Reinforce everything and wait for them to return.
