-Prologue: Folded Space-

On the frontier planet of Typhon, a major battle was raging across the landscape between the Interstellar Mining Corporation (IMC) and the Militia forces. Both sides locked into a war over the future of the Frontier; with the IMC looking to retake control after their humiliating defeat at Demeter, and with the Militia forces unwilling to accept the former's 'forced occupation' of their colonies. Less than several hours ago, they had just recently discovered the IMC's plan to destroy their entire home planet of Harmony in a single sweep, forcing the militia to surrender unconditionally. The Marauder Corps branch of the militia, along with mercenaries from the 6-4 began an all-out siege towards the IMC's base.

Among the midst of a nearly-destroyed IMC control room stood a towering robotic figure known as a Titan. The lumbering machine was collapsed on the ground along with its pilot, trapped inside the cockpit. Beside them was a mysterious device known as the Fold Weapon; a tool used to bend space and time, with catastrophic results. Something they needed to destroy at all costs.

"Cooper, I require your assistance." The Titan, now known as BT-7274, said to its pilot with garbled distortions in its voice. "My auto-navigation systems are offline. Get me into the injector assembly and control station, we must do this together."

'Got it,' the militia rifleman-now-promoted-pilot known as Jack Cooper thought to himself. He began to manually operate the controls of the Vanguard Titan while simultaneously attempting to treat his wounds during his previous engagement against the Apex-Predator pilot known as Slone. "Grk!" He began to wince in pain as he began to self-administer a stim-pack over his injuries.

"Pilot, are you alright? My current damaged systems do not allow me to detect any changes in vital signs effectively," BT had said in response to its pilot's grunts of pain. Cooper could only ignore his Titan's concern over his well-being, as he placed his entire focus on multitasking.

"Incoming signal from Commander Sarah Briggs. Boosting Signal," BT suddenly said.

"BT! Cooper!" The radio voice began to speak frantically. "Our ground teams can't make it there in time. You've got to find a way to destroy the Fold Weapon from the inside, there's no other way!"

"Commander Briggs, I believe I have a solution," replied BT. "In the Ark's exposed state, a Titan's battery unit may be able to overload the Fold Weapon's control panel."

"In other words, set off the explosion here on Typhon instead." Cooper commented.

"Correct."

"Alright then Cooper, send us dropship coordinates for an extraction point. We're getting you and your Titan's SERE kit out of there," said commander Briggs over the radio.

"Negative," the Vanguard-class Titan replied. "The calculated blast radius will be too large, and the current emissions on the Ark will interfere with the ship's jump control navigation."

"Dammit!" Cooper said to himself. "So, now what?"

"During our previous engagement against the Apex Predator, Slone," BT began speaking again. "the pilot appeared to be using a device similar to the one found on Major Anderson's body."

"That explains how she was able to keep phasing in and out of combat for so long, and become such a pain in the ass to target-lock" Cooper jokingly remarked. He should've known that these paid mercenary elites for the IMC must've had some tricks up their sleeve.

"Correct," replied BT. "Pilot, if we were to activate the time manipulation device at just the precise time, there is a 15% for us to survive the blast radius, allowing us to signal a safe rendezvous point with the Militia fleet." The brief shift in time would give Cooper and his Titan ally enough time to signal Commander Briggs for a safe extraction point. "Transferring partial AI functions to commander Briggs."

"And the other eighty-five percent?" Cooper asked as he got out of the Titan and began to search through the Ion titan wreckage containing Slone's corpse.

"Unknown. Results of incomplete teleportation may lead to catastrophic injury or death. Similar to Major Anderson's predicament"

"Those aren't exactly great odds…" Cooper commented as he pulled the time-travelling device off Slone's mangled body along with her CAR submachinegun. After strapping the gauntlet onto his arm, the pilot scavenged a few batteries off the destroyed Ion titan, tossing them to BT. "Rather not end up wedged between two different buildings and half the person I once was."

"They are our only odds," the Vanguard-class Titan retorted before jamming the battery units into in injector control panel, causing it to overload and begin a failsafe explosion countdown.

*Fold Weapon Malfunction. Initiating Fail-safe Destruction Sequence* A large timer hologram began to project through the central corridor, counting down from thirty seconds.

"Trust me," BT calmly said to its pilot before Cooper jumped back into its cockpit. "Protocol 1: link to pilot. Protocol 2: uphold the mission, we have successfully destabilized the Folding Weapon into self-destruction. Protocol 3: protect the pilot.

"I sure as hell hope so," the commander remarked before ending the radio transmission. "We'll meet you on the other side. Good luck, to both of you. Briggs out."

"I've integrated the time travelling device onto your AI system. Don't worry BT, I'm not going anywhere." Cooper said from the cockpit as he his thumb was over the mounted switch.

"Copy that, pilot. Activating time-distortion in 3 . . . 2 . . . 1. . ."

Just as they had activated the time travelling device, a bright blue flash of energy from the now destroyed Folding Weapon appeared before the two, blinding them. Before either of them could react, residual energy from the Ark caused the pilot and his Titan to vanish. Leaving behind the bodies of dead IMC grunts and titans in the process, before a massive explosion fractured the very planet's surface and core.

*Meanwhile, on a Militia fleet ship orbiting the now destroyed planet of Typhon*

"Shit! Sarah, we just lost signal of BT and Cooper, and I'm not picking up and scans of them across time either!" Screeched Barker.

"It can't be…" the commander thought to herself for a moment. If they couldn't detect any signals or readings from BT or Cooper, especially through primitive means like Morse and binary code, then there was only one possible outcome for the two; a solemn realization for the both of them.

'They . . . they didn't make it after all.'

'Harmony, the Militia calls this place their headquarters, but millions of other call it home…' Briggs thought to herself. The Marauder Corps commander began to give a salute towards the destroyed planet. "Pilot Cooper, BT, a lot of people owe their lives to both of you, thank you."

After a brief moment of silence among the rest of the saluting passengers, Briggs continued. "Barker, set a course for Harmony, take us home."

"You got it."

*Somewhere, in what appeared to be in the middle of an empty void, a familiar SRS-painted Titan containing its pilot could be seen drifting in the vast emptiness*

"Grrrgh, hmmrph…" Groaned Cooper as he began to open his eyes and move his arms. "What was that blast? I thought we were goners for a moment there."

"Pilot, are you alright?"

"Yeah, I'm fine…but, where the hell are we?" the now fully-awakened pilot asked his Titan partner.

"Accessing files…location unknown. It appears that I am also unable to contact Commander Briggs through all forms of communication."

"Even through binary and Morse code? What about your transferred functions?" Cooper wondered, as he began to activate the switch for time warping. "How about we jump back and signal them from there, BT?" A small humming sound began to emit from the arm-mounted device

*buzz*, *click*, *click* The area began to flash in an instant in bluish light. But against his avail, nothing happened.

"Well, crap." The pilot said to himself. 'Alright Jack, no time to panic now. We just need to find a way back into our original timeline, and we should be good,' the mildly distressed pilot thought to himself. "…So how are you holding up, BT?"

"On the contrary to our current predicament, it seems the time distortion has fully restored all critical functions and armor systems to standard condition. Additionally, we have successfully fulfilled protocol 3, protect the pilot."

'Yeah, for the time being,' Cooper thought to himself. Riflemen training taught him how to survive in conditions of scarce resources several weeks at a time, but not when there's no resources at all. Even he knew better himself that the best pilots out there can die to starvation or dehydration, it was only a matter of time until he was one of them.

"Pilot, incoming transmission signal." The sudden announcement threw Cooper off his current train of thought and seat.

"Who's it from?" 'Hopefully it's the rest of the Militia fleet,' the young pilot thought to himself.

"Decrypting message, source of transmission appears to be from an entity designated as, 'Histoire'"

-End of Prologue-

A/N: Hi everyone, Megazord here! I hope you all enjoyed the introduction chapter of this Neptunia x Titanfall crossover. Seems that Cooper and BT have a new mission in their hands real soon. Rest assured, I don't plan on any OoC, Self-inserts, or Lemons in the fanfic. Though it seems that Titanfall 2 characters haven't been added to the category database yet (seriously, where's my Jack C. and BT-7274 on here?). That aside, this story plans to take place in an 'alternate ending' to Titanfall 2's campaign and into R;B1's storyline (sorry Nisa and Gust!). Next chapter should be coming out real soon!

Please be sure to R&R, thanks!
