Chapters -couple days earlier-
Rainbow Dash is sitting in her room in exhibition. She knows that she will be going on a mission soon to ponis. After Flash Sentry was presumed missing, Rainbow Dash knew it would be time to start the mission.
"Dash, if you want to go to armory station, than we'll be leaving soon. go get your stuff"
"Alright, this is an important thing to do."
Rainbow Dash walked towards the armory to collect some supplies. The armory at this station knows of her mission so they won't charge her for supplies.
"Hello dash, we have your equipment here" Said Flim. "Flam has got it ready."
"Well that's great then" Replied Dash.
"Well we're just sorry we can't give you the best stuff."
"That's alright, i could get more stuff at armory station"
"Well to start off you're going to need a gas mask. Without it you'll be dead on the surface and other areas even here in the metro."
Flim pulled out a gas mask. It was a clear face one that most stalkers use on the surface.
"You're also going to need some filters or the gas mask is just an accesory."
Flam went to the back storage room and came back with some filters.
"You might need this universal charger. It's good for over-charging your flashlight but it could be useful for other stuff too."
Flim pulled out a universal charger and handed it to Dash.
"You are going to want a medkit. The syringes will boost your health when you're in a fight. You'll be in a lot of fights."
Flam came back with a medkit capable of holding 5 syringes.
"But the main thing that you need is a weapon. Why go out without a weapon? You'll be a sitting duck"
Flim reached down and grabbed a Bastard sub-machine gun.
"It's not the best gun, but it's what'll have to do. It has terrible accuracy, but i think you'll do fine with it."
"But what is a gun without bullets? There are some bullets at the firing range. You can even test your gun there if you like. Good luck Rainbow Dash."
Rainbow Dash took the supplies and bullets and tested out the Bastard. Flim was right, this gun does have bad recoil but it looks like it can be easily fixed and made here in the metro.
"Thanks for the equipment and are you sure i don't have to pay for these?"
"Passing your message onto ponis is going to give them a reason to help this station." Replied Flam.
"Well bye Flim Flam."
Rainbow Dash proceeded towards the rails where a cart will take him to Armory with a few other ponies.
"Dash are you ready?" Said AppleJack.
"Yeah i'm ready to go"
"Ok let's go then"
"Hey can i get a ride you guys?" Said a pony nearby
"Only if you push the lever." Replied Applejack.
"Heh. I can do that."
The pony climbed onto the cart and they set off.
Rainbow Dash climbs up a ladder underneath Shining Armor. The tunnel was dark and and not pleasant, but that was basically how all the metro was like.
They come to the top of the ladder into a hallway filled with lockers and crates.
"Check the crates and lockers for supplies" Said Shining Armor.
Rainbow Dash reluctantly checked the lockers which were filled with ammo. The crates weren't filled with anything good and Rainbow Dash left them behind.
They walked up some stairs approching an armored door. Shining Armor used the manual opening mechanism to open it enough to go under.
"This place is quite the place" said Shining Armor Sarcastically.
"Yeah, I'd TOTALLY want my house to be here" Rainbow Dash blurted out.
"Well were almost to the surface. Just don't forget to put on your Gas mask before we get up there."
"Yes because i'm totally going to walk up there and reveal i'm really a mutant" replied Dash jokingly.
The two put on their gas masks and went for the surface. The Surface wasn't as radioactive as it was before, but the air was still as poisonous as ever. You could only breathe the air for 30 seconds before it started poisoning you. But your lungs wouldn't be able to use it anyway and you'd start suffocating. There are still radioactive patches on the surface so Stalkers and dwellers always have Geiger counters with them so they know not to travel there for too long.
"Welcome home Dash."
"Yeh it doesn't look much like home."
"Well it was home for a short time"
Suddenly, some watchers started attacking them from above.
"SHOOT THEM NOW!" shouted shining armor pointing his weapon up and shooting the watchers.
Rainbow dash held her weapon and shot the watchers above. She had a good aim.
"Ok We're almost with them" Said shining armor leaving the building
The two walked over to were a ranger squad was outside.
"Hey you made it!" said one of the rangers.
"Of course we did" said Shining Armor.
"Yes because we totally suck at surviving" Said Rainbow Dash sarcastically.
Suddenly a wave of demons started attacking them and they tried to stand their ground.
"SHOOT THEM NOW!" said a ranger to the gunner on the vehicle that Rainbow Dash never noticed.
But it was hopeless, they were overrun. Rainbow Dash witnessed most of them being teared apart. But suddenly a demon charged at her.
Rainbow Dash, Applejack and the pony that never specified it's name set off along the track towards Riga. It wasn't supposed to be a hard trip but it wouldn't be easy.
"I've never left Exhibition before" Said Rainbow Dash.
"Well you should check out all the other stations" Said AppleJack.
The metro's were dark and eery. Some ponies are lucky to live up to 50 years here, not that ponies have been here for 50 years. Here, ponies are all basically the same. No one knows where all the alicorns went. Only Twilight Sparkle remains here from the 4 alicorns.
Even though it was deemed safe here, the air was still quite toxic and after just 1 year, it was revealed that the air was toxic enough to weaken ponies quite significantly
Unicorns were weakened to the point that their magic was enough that it could only be used as a light source. Pegasi were weakened to the point that flight was impossible and their wings could only be used for other things. Earth ponies were weakened to the point that it was hard to tender any land, but considering that photosynthesis is practically impossible underground, ponies reverted to mushrooms that didn't require photosynthesis and could grow in more places than normal plants.
With excessive use, metro stations are very eery and are not pleasant. No one liked living here, but they had no other choice. The surface of Manehatten was damned and some other areas underground are either owned by factions or mutants. To survive here, ponies mostly relied on the stalkers for supplies.
"It shouldn't take very long to get there"
Just then they came to an intersection and were stopped by two guards there.
"If you're going to Riga, you're going to have to take the service tunnel. The tunnel has been collapsed over and requires cleaning out. You have no other choice."
"C'mon, i hate that tunnel" Said AppleJack
"Everyone does. But there's no other way"
"Alright open it up"
The guard opened up the service tunnel and the 3 proceeded to go through the tunnel.
"I want to get out of here as fast as possible."
Suddenly they begin to pass out as an anomaly starts to pass by them.
Rainbow opens her eyes to see Flash Sentry supposedly getting attacked by a Dark one. The background was white so she had no idea what was going on.
"Aahhhhgh" Screamed Flash Sentry.
Rainbow Dash wanted to do something. But the Dark one prevented her from moving and she saw the light.
Rainbow Dash woke up to find them making their way through the tunnel at a decreasing rate. Rainbow Dash swore they weren't out for that short of time. Any longer and they would've stopped right in the middle of the tunnel.
"Huh?"
Rainbow heard the sound of what appears to be a nosalis.
"Wake up AppleJack!"
Rainbow Dash rapidly shook AppleJack trying to awaken her.
"Wuh what? Oh shit!" Shouted AppleJack quickly pushing the lever to speed up the cart.
Suddenly in the distance AppleJack spots a group of Nosalises catch up to them.
"Shoot them! For the love of Celestia, Shoot them!"
Rainbow Dash leveled her Bastard and proceeded to shoot the incoming Nosalises, Few of which managed to jump on the cart.
"Here take my shotgun"
AppleJack passed a Duplet double-barreled shotgun to Rainbow Dash who proceeded to continue kill off the Nosalises. Albeit more effectively.
"Damn Flim should've given me a Duplet." said Rainbow Dash.
Suddenly one Jumps onto Rainbow Dash and attempts to kill her. Press X repeatedly.
"You want to fight me?" shouted Rainbow Dash who pulled out her knife and Decapitated the Nosalis' Head.
Another Nosalis jumps onto the cart, but instead jumps onto AppleJack.
"GET IT OFF ME!!"
Rainbow Dash grabbed one of AppleJacks Grenades, lit the fuse, shoved it down the Nosalis' Mouth and kicked it away from the cart killing the Nosalis and half the Nosalis horde
Suddenly a Nosalis Jumps up and manages to bring Rainbow Dash off the cart and down to the ground. Rainbow Dash quickly hid in a nearby hole in the tunnel while the rest of the Nosalis ran past and suddenly died from gunshots.
"Wait! I'm still alive!" She shouted.
She quickly ran up to where the cart had stopped before the flamethrower was put to kill of any remaining Nosalis.
