The scene opens up in Sector 09, somewhere in Safehouse 03. M4, M16, AR-15, and SOP2 went to the safehouse as when they had to fend off a large wave of Sangvis T-Dolls, Agent came inside and everyone is shot, but as everyone fell to the ground, a bright flash goes off as when the flash had cleared, M4 and the others were nowhere to be found.

In the year 2020...

M4: What the... where am I?

M4 found herself in a ruined classroom, and as she opened the door, she heard someone yell out in a commanding voice. 

Recker: HEY PUT THE GUN DOWN! 

M4 had quickly trained her weapon at the person who yelled at her and the person looked like a MARSOC Marine, and he had a SCAR-H with a Holographic Sight, a PEQ-15 IR Designator, an Angled Grip, and a Muzzle Brake as M4 yelled at him with a commanding voice as well.

M4 points her M4A1 to the stranger and yell back at them.

M4: WHO ARE YOU AND WHY AM I HERE?!

Recker: WHO THE HELL ARE YOU, HUH?

M4: MY NAME IS M4A1, A T-DOLL OF THE AR TEAM! WHO ARE YOU?!

Recker: Calm the fuck down. I'm Sergeant Daniel Recker, US MARSOC, 7th Fleet.

M4: MARSOC? You mean, Marine Raiders?! You're with the Marines? What are you doing here?

Recker: We're here to collect intel on a Chinese admiral named Wei Chang. And if you don't want to be killed by the Russians, follow me.

M4 lowered her weapon after she heard the mention of Russian Forces.

M4: W-What?! The Russians are here, too?

Recker: We don't have time to explain.

M4: Where exactly are we going, Sergeant?

Recker: The Safehouse.

Recker opened the door as several crows went out, and then Recker gets a Glock 19 uncomfortably pointed at his face by Sergeant Clayton "Pac" Pakowski. 

Pac: Drop it! Dammit Recker, I almost shot you in the face. You lost your tail? 

Recker: Just lost them Pac, just found someone here 

He gets cut off as the two Marines see their Squad Leader, Staff Sergeant William Dunn. 

Dunn: Ease up, you two, and who's the girl with the M4? 

Recker: Her name's M4A1, and she's part of the AR Team, but it looks like her fellow teammates aren't here. 

Dunn: She's a temporary member of Tombstone until we find the rest of her teammates. 

Dunn goes to the windows.

Dunn: Shit, it's already daylight. We're going to the extraction. You got a '20 on Irish?

 Pac thought of it. 

Pac: Thought he was with you..? 

Dunn decided to break radio silence.

Dunn: I'm breaking Radio Silence, Tombstone Three, Tombstone Actual, what's your 20?  

Irish: Tombstone Actual, inbound from the north, coming in hot, requesting cover fire, on my retreat! 

Recker: Clean copy Irish, we're on it!

Recker and the others, except M4, removed the window boards.

Irish: You got my ass? 

Recker: Clean copy, Irish! *to M4* Get some ammo from that crate and take position by the window!

M4: Got it, Recker. I'll get ready.

They all got to position as they saw Irish jump out of a window, and he killed a dog with his MK48 Mod 0. Then he took cover as everyone else fired their weapons at the Russian troops, and then they pulled Irish up.

Pac: You okay, Irish?

Irish: The Safehouse might not be so safe after all.

They moved out, and then Recker spots the enemies, and then he said this.

Recker: Below us, in the atrium. M4, give the signal, and we'll fire on your go.

M4 gave them the signal, and they killed the Russian troops below them, and they killed off more enemies as they went down a hole.

Dunn: Everyone okay?

Recker: All good.

Pac: Same here.

Irish: Still standing.

M4: No hits on me.

Recker: Dunn.

Dunn: Yeah?

Recker: 'Kept an M320 with me. I'll blow the wall to hell.

Recker fired the M320 at the wall as a large hole was now in it.

Dunn: Wonderful. Let's move to the extraction.

They went out as Firebird 2-1, was heard on the radio.

Firebird 2-1: Tombstone Actual, this is Firebird 2-1, we're inbound. What's your ETA, over?

Dunn: Good to hear you Hawkins, we're making progress.

Firebird 2-1: Get your squad on the roof of that building. Don't keep me waiting.

They were about to go down a ledge until Recker stopped M4 and gave her a tactical visor.

Recker: M4, scan the area.

M4 looked through the area.

Recker: See anything through the Tactical Binos?

M4: I can see the factory. Four shooters are getting off trucks, too. Let's go.

They all got down and then Recker and M4 killed two Russian Troops silently, then Recker grabbed his Glock 19 Sidearm, and then he shot a Russian Soldier in the head and M4 kills the other as they saw more Russian Troops coming, until Firebird had taken down the Russian Troops as everyone started fighting their way to a drain pipe as Recker fired his M320 at a Flammable Tank and then it exploded, and then everyone killed the Russians by the drain pipe, and they were now outside the Factory as Firebird left and Recker fired his M320 at the incoming trucks with Russian Troops. And they pushed into the factory and they talked.

Irish: Hey, why the hell are you named after an M4?

M4: It's because I'm a Tactical Doll, or a T-Doll for short. I'm basically a robot, but  we have emotions. And we could feel pain.

Recker: Got an idea when you were used?

M4: 2062.

Dunn: In the future? I guess we got replaced by T-Dolls in combat.

M4: No, actually... Humans like yourselves, you're our commanders. Most of us need a leader, so Humans like yourselves are suitable.

Pac: Huh, that's convenient. Although who created you?

M4: Griffin And Kryuger, it's a PMC, and we're fighting an enemy known as Sangvis Ferri. It's a company whose dolls had went rogue and killed all human personnel.

They all get in the elevator until Firebird was heard on the radio.

Firebird 2-1: Tombstone Actual, radar's lighting up, you've got Hostile Air!

Pac: OH FUCK!

Irish: GET DOWN!

Dunn: DOWN!

Recker: STAY THE HELL DOWN!

The MI-28 Havoc instantly destroyed the elevator and they started running to the top, until the Havoc fired at the roof and then Firebird had to get off the roof as the building was falling apart, and then M4 kills two Russians and then she slid down as Recker catches her and she caught Dunn.

Firebird 2-1: SHIT, I'm hit!

Firebird 2-1 had gone down and then they all fall off as Dunn was killed in the fall and Recker got up and saw M4's feet on the rubble as he lifted it up.

Recker: You okay? Pac, any signs of Hawkins or anyone else in the chopper?

Pac: Negative, Reck.

Recker gave M4 his Glock 19 as Recker was now equipped with Dunn's MP412 REX Revolver. Then an SUV came as Recker grabbed his SCAR-H  and then the driver had gotten out. Then everyone got inside as M4 got behind the wheel and Irish contacted Captain Roland Garrison.

Irish: Fortress, this is Tombstone. Our evac is gone, and we've got a new girl with us. Do you copy?

Garrison: Fortress is tracking you, secondary extraction en route, follow the road, three klicks west.

Irish: Copy Fortress. En route. Any sign of the chopper?

Pac: Dunno, I'm looking!

M4: Now what, do we get the hell outta here before the chopper gets us?

Recker: Seems like it. 

As they were inside the tunnel, they saw an MI-28 Havoc fire at them from the left as they keep driving until M4 fell out of the SUV, but got caught by Recker as he gave her his M320.

Recker: BURN THAT ASSHOLE!

M4 aimed the M320 and hit the Havoc on the Cockpit as it crashes, but M4 lost control and then they crash into the sea. But not until M4 shot the windshield with her Glock 19.
