Author's note

This is my first fan fiction so I'll be trying my best to make it a good one. This is set in the TF2 MVM time (if you don't know what MVM stands for its Man vs Machine in TF2 a very fun game mode) and the first few chapters will be placed in Mannhattan if I'm doing a bad job at describing (which is a high chance) the charters you can type up their images for the RWBY charters because I'm a lazy son of a gun but for the TF2 charters like Scout, Medic, Pyro and the other 6 classes I'm using my TF2 loadouts so if you're wondering what they look like add me on Steam my name is Dark Descendant{HG}. And before I start I'm not doing any shipping. Anyway let's get this story rolling. Also credit to WongTheGreatAndPowerful for describing the robot engineer, being my beta reader and fixing up and spelling errors and making it sound good.

Chapter 1: Something Unexpected

Saturday - 11:30am – Remnant - Streets of Vale - Team RWBY:

"Yang I'm SOO bored right now!" Ruby moaned.

"Come on Ruby, lighten up! I'm sure we'll find something fun to do." Yang told a bored Ruby

While Yang was doing her thing as an older sister, Blake was engulfed in a book and Weiss flicked though a magazine. But then Blake heard a strange clunking noise in an alley. "Did anyone here that?" she asked the group, but was met with shrugs from Yang and Weiss and a "Nope." from Ruby. Then another noise reached her, but this time it clearly sounded like metal hitting metal, and was loud enough for the group to hear.

"Was that the noise you were talking about?" Weiss questioned.

"Yeah" Blake answered. At that moment, a streak of blue light flashed in a nearby back alley.

"Let's go see what it is!" Ruby half yelled with excitement. After a 2 minute walk to the place where they guessed the blue light came, they were greeted by a startling sight. A blue robot with one grey and one yellow hand, and a grey strip below the palm of his robotic hand, a strip of grey metal above it's legs which would have been its belt. On the right side of its 'belt' a power cord wrapped up like a cowboy lasso, with the left occupied by two large batteries, mostly coloured blue expect the top of it which was grey and the power symbol which was yellow. Its feet were black with yellow metal knee plates, its head was grey with yellow flashing eyes, the top of its head was also flashing yellow. Its blue arms were stamped with a scratched yellow symbol of a wrench.

After having a quick glance of the robot, they decided to take a closer look to see what it was doing, so they hid behind a dumpster, except for Weiss, who climbed a fire escape.

"Weiss, what is that?" Ruby whispers to her partner.

"I don't know, it's not one of my father's models." she answered.

Then the robot placed down a blue tool box of some kind, which morphed into a strange rectangular object, during which the robot said in a robotic Texan voice, "Teleporter going up."

'Teleporter?' Blake thought to herself.

After, the robot did a 180 spin and held another tool box. But what it said next was quite worrying for the Huntresses.

"Building a Sentry."

As this sentry was being built, it unfolded into a simple gun barrel in a rounded edged box mounted on a tripod. Then the robot whacked it with its wrench roughly 10 times and all of a sudden, the box which the muzzle was mounted on burst into two small mini guns with some sort of chains coming out and another leg sprouting behind the original tri-pod. The box was now what the robot said to be a teleporter but instead of being large it was small and it could hold the weight or an average human on it. A stand was keeping the teleporter upright but above the stand the rectangular shape was spinning and creating some sort of blue circle. Now looking back to the sentry it was different it was taller ¾ the size of the robot, now the sentry had 6 legs holding it up, the blue gun barrel was now in a vertical position and attached to the gun was another box with 4 holes in it.

As Ruby quickly glanced up into the sky to see if the sun had started to set, which it hadn't. She saw a dove flying pass over the alley where the sentry was. The sentry automatically aimed at the dove and shot it down without missing a shot. The sudden gunfire startled Ruby and caused her to knock over a bottle on top of the dumpster. The sentry stared to spin up its two miniguns, which where then aiming at the dumpster. As soon as it started firing at Ruby's position, Yang and Blake jumped out to distract the sentry, while Weiss jumped of the fire escape and went to help her team. As the sentry was firing the box which was attached to the gun barrel shot four rockets which missed the Huntresses, exploding the dumpster.

After a few minutes of evading Weiss summoned some glyphs to deflect the oncoming lead and explosives. The sentry again shot 4 rockets at Ruby which threw her behind the machines. As soon as she got back on her feet, she thought to herself, 'This is my chance to take out the robot!' With her sweetheart Crescent Rose unfolded into full scythe form, she started to sprint towards the robot. But in ending the robot, she accidentally ran over the teleporter. In a flash of blue light, she was gone.

The rest of the team stared in shock at what they just saw.

"RUBY!" Yang screamed.

"THROW EVERYTHING YOU GOT AT THAT PIECE OF S***!" she commanded. All that filled the alleyway was the crunching of metal as the sentry was pummeled by gunfire, Dust explosions, and Yang's flaming gauntlets.

After 10 minutes of bombardment, the smoke cleared, revealing a pile of smoking metal and the teleporter.

"I'm going though that thing." Yang said with a determined tone.

"Yang we don't know what's on the other side of this teleporter.", Weiss objected. "For all we know it could be more of those robots."

"I don't care! I want my sister back, and if you don't want to risk your pretty little face, that's fine! I'll do it by myself."

Yang stared at the heiress with anger contained in her eyes, with Weiss looking back with hurt at being accused of not worrying about their leader. They remained like this for some time, until Blake's words snapped them out of the staring contest.

"Weiss, she's our team leader and your partner. If you can even consider leaving her alone, then I am ashamed to be your 'team mate'. However, we can't just charge in recklessly Yang. We should instead proceed with caution and enter the other side of the teleporter with the intent of sneaking."

"Fine, but the moment I see Ruby, I'm going in gauntlets blazing." Yang huffed, agreeing to the plan just to get Weiss to go.

The heiress sighed, and relented. "Ok, I'll come. But if we can't find a way back to Beacon afterwards, it's going to be your fault."

"Good and YOU'RE going first!" Yang ordered.

"Wait what?! I never agreed to going fir-"

Just before she could finish her sentence, Yang pushed her into the teleporter. She disappeared in a blue flash just like Ruby did, with Blake and Ruby close behind.

Tuesday – Manhattan – 2:32 PM - Weiss, Blake and Yang P.O.V.

After entering the teleporter they ended up on top of some red and yellow shipping containers, and to their surprise the same teleporter they jumped into was spinning away under Yang.

"So where are we?" Weiss questioned Blake.

"I have no idea" she responded.

Yang's eyes were scanning everywhere for her sister when she head the same clunking noise that led them to the robot earlier. She turned the corner and instantly told the others to get ready in case the three revealed robots started attacking them. As Team WBY studied the robots they began to see differences from the one earlier. For starters, the robots all had yellow flashing heads, were different sizes, all had grey scratches, the robots were shooting a blue beam to another robot, and they were all marching in the same direction. Then all of a sudden a shot rang out. One robot dropped to the ground, missing its head. The rest of the automatons soon followed suit. Then the three huntresses heard talking.

"Wow Ruby. First time with my rifle and ya already landed your first head shots on these wankers." a heavily Australian accented voice spoke.

"Well I was always a good shot with my baby, but it was fun taking a few pot shots with your sniper, Sniper."

"Bah, just call me Mundy."

"Alright then."

Then all of them heard a nearby speaker announce, "Wave done. Quickly get to an upgrade station, they'll be back."

After, Yang, Blake and Weiss got closer look they saw Ruby with some sort of sniper with a robot head hanging down from the muzzle in her hands. Standing next to her was a tall and spindly man who was they assumed was 'The Sniper' or as just mentioned, 'Mundy'. Yang was about to start sprinting and hug her sister, but she was stopped by a French-accented voice.

"I wouldn't move if I was you."

As the three girls turned around they saw a man with a red tux, a black hood (The Dashin' Hashashashin), yellow glasses (Deus Specs), a red scarf (Merc's Pride Scarf) holding a revolver at them (The Diamondback).

"Why are you girls in this part of Mannhattan, it was closed off to everyone but mercenaries and Miss Pauling.

"Spy, what are you doing?"

The newly deemed 'Spy' turned to face the source to the voice.

"We're all down at the upgrade station and you're here doing… well, hello there ladies!" the man said as he turned to Weiss, Blake and Yang.

"Scout you imbecile, don't you have to take care of the other girl who appeared out of the teleporter?" the Spy asked in a mocking tone.

"Nah, left that job for the Sniper. Those two seem to get along with each other better."

"That's my sister!" Yang exclaimed.

"Really? Sorry, but you're going have to prove it. First, what is your name?" the Spy inquired.

"If you'd be so kind as to stop holding that gun to my head, I'll tell you." Yang said through teeth gritted in annoyance.

"Fine." the Spy said while holstering his weapon. "But what about these two? Are they with you?"

"What do you think" Weiss said with a sarcastic tone.

Yang got up and held out her hand. "The name's Yang." she introduced. "The Ice Queen over there is Weiss."

"Hey!" Weiss objected in annoyance.

"And that's Blake over there."

Instead of saying anything, the faunus just looked over the Spy.

Then they heard Ruby yell out, "Guys, is that you?!"

"Ruby?! Thank goodness you're safe!" Yang called in response.

After Team RWBY was all back together, Yang asked, "What happened to you when you went through the teleporter?"

"Allow me." the Sniper interjected.

12 minutes before Weiss', Blake's and Yang's arrival - Sniper's P.O.V.

Was just a normal day of sniping wankers' heads off. Just after I respawned from one of those robot spies backstabbing me, I heard the Heavy yell out, "Robots have taken gate!" For a while a noise was heard, signalling that a gate has been taken and the robots have been deactivated for a short time. As I looked at the teleporter exit, I saw a robot engineer get a teleporter set up along with a sentry. A bullet to the robot engineer's head stopped the construction, and in a hushed voice I said "Boom! Headshot." Then a whistle was heard that signalled the robots were back online. The sentry was online, but out of the teleporter I saw a little girl in her teens destroying the sentry with some short of a red scythe. She then looked puzzled as she folded the scythe up. I think she somehow ended up in the tank and tripped over the teleporter. So I took our engineer's teleporter and teleported to the exit where he set it up and as soon I appeared, she was looking at the teleporter I just used.

"Oy, you lost?" I asked. Suddenly, she unfolded and pointed the scythe at me.

"Easy there little missy, I'm not trying to cause any trouble. I'm just wondering if you got lost, 'cause this is a battle ground." Right then, I notice Scout running towards us, but he was slower than normal so I quickly turned my head towards the gate. And sure enough, the real Scout was there collecting cash and throwing Mad Milk at the robots. Assured that the Scout which was running towards us was a spy, I pulled my Kukri and stabbed the spy in the gut. The girl was shocked as she most likely thought I just murdered someone, but as I pulled my blade out, the robot Spy revealed itself.

I turned to her and asked "Oy, you just going stand there or are you going to get to safety?"

"Uh..." she answered.

I sighed and decided to start from the start. "Right then little girl, what's your name?" I asked.

She haughtily replied, "My name is Ruby Rose, and I'm not little! I'm 15 years old."

"Ok then Ruby, could you do me a favor and head to that building over there?" As I pointed to the spawn, I heard Medic from the battle field calling me.

"Sniper, vhere are you?!"

"Coming mate, just let me deal with something ok?"

"Make it quick!" Medic replied.

"Ok I can't let you near those robots so I'm going to give you one of my rifles."

And this is where she just stared at me with a face that mirrors Heavy with a Sandvich. "Rifles?! You mean you have more than one?! Please, please, please show me!" she squealed as she jumped up and down.

"Ok, ok. But only one!"

"Ok." Ruby squeaked.

I walked to the spawn. I saw Engineer repairing the teleporter.

He just stared at me and said, "Boy, you are going to get in trouble for bring a civilian here."

"She probably ended up in the tank and tripped over their teleporter and ended up here." I responded.

"Ok, so why are you bringing her here?"

"I have a name you know!" Ruby shouted.

The Engineer looked at her and asked, "Well than what's your name miss?"

"Ruby Rose." she answered shyly, ashmed at her outburst.

"Right, now Ruby, what's that on your back?" pointing to her folded up scythe.

"Oh this?" she asked as she unfolded her weapon and stuck the blade into the ground.

"This is my sweetheart, Crescent Rose. A high impact bolt action sniper scythe." She answered.

"Looks like you got a challenger Sniper!" Engineer said to me.

I replied, "Shut it Engie!"

"So can I see your rifles now, please?" Ruby asked.

"Ruby, tell ya what. If you can shot more robots than me when the wave nearly ends, I'll let you have a shot of my sniper. Deal?"

And just like that, she replied with "Deal."

As Engineer just looked at me with a 'you're-in-for-it' look, Ruby asked "Sorry, but one could I have your names please, and two is that thing safe?" she asked pointing at the teleporter.

Engineer promptly told her, "Ok, for starters we don't use our proper names 'cause that's classified. We get nicknames based on our roles on the team, so I'm the Engineer and this bum who helped you is the Sniper. And yes, the teleporter is safe but don't teleport any bread."

"Why?" she asked, and I answered, "I'll tell you all about it later, but for now, ladies first." as I gestured her to take the teleporter.

She flashed a smile at me and stood on the teleporter and went from point A to point B.

As soon the teleporter was recharged Engineer told me, "It's your fault if she dies."

And with those words of inspiration I left him, and stood on the teleporter and went from point A to B. Ruby was waiting for me, and she was already way ahead of me in kills, so I tried to get as many shots off, but I couldn't keep up with her. After a while, there were only a few bots left, so I gave up. She folded up her weapon and I gave her my sniper to shoot the last few enemies.

Present time – Group P.O.V.

"That was...interesting." Blake said. "And do you really have a whole collection of sniper rifles?"

"Sure thing … um..."

"Blake" she finished for him.

"Now where are we?" Weiss asked.

"Manhattan." Scout replied.

"I haven't heard of that city on Remnant." Yang said.

"Remnant? What is that, a state or something?" Spy asked.

"It's the planet were we live in! Ruby, Weiss, Blake and I." Yang answered.

"Nein, you are not on Remnant anymore. You are on Earth." a man with a heavy German accent said while walking up to Sniper and backhanded him.

"Vhy didn't you tell me we had guests?"

"OW! Medic, I'll tell you later but for now we need to get ready for the next wave and tell them what's going on."

"But we need to explain this to Miss Pauling when she picks us up for our next location." Scout said.

Then Blake questions Scout, "Who's Miss Pauling?"

Ok this is going to be my first chapter of a New Mean of Defence and my Medic has the Nunhood, Angle of Death and Fashionable Megalomaniac. My Scout has Fed-Fightin' Fedora paint gold, The Flapjack and Dillinger's Duffel. My Engineer has The Danger, The Dogfighter and Hillbilly Speed-Bump. And finally my Sniper has Hillbilly Speed-Bump, The Cold Killer and The Birdman of Australuactraz. And I've already explained my Spy. Anyway I hope you have enjoyed this chapter and I'm thinking about adding in Femsniper and Femscout into the story as well as Team JNPR and Saxton Hale. Give me suggestions on what to make the Femsniper and Femscout look like I said I might put them in so who know anyways I'm off to play some Team Fortress 2
