An: I don't own Titanfall, Hawaken, or Mass Effect. This is not a SI, and also ill make up thing from the Titanfall history, so consider it AU until more info comes out for TF. also this is AU if you didn't piece it together yet and/or are actually reading this AN.

In a Corridor.

I woke up with a headache unsure of what happened as there were limp bodies on the floor. I remember that the ship was attacked by MIC, since we had a lot of prototype titans (Hawaken's mechs) and a prototype ship defense system, a shift based one, with only a skeleton crew, that half doubled as a security if needed. The Captain activated the defense system, and the warp drive. (I think that's their FTL tech, but don't quote me on it.)

End result was that everyone was knocked out or dead. I turned my head lamp on my helmet and headed to the bridge.

At the bridge

Once at the bridge, I checked the systems and mechs on the large space tanker ship, similar ship to Annapolis. The ship was trashed and it was barley holding together, the few defense guns and the new defense system were currently inoperable, life-support was at 42% and falling slowly, and we were leaking atmosphere slowly. The only thing that was working was the backup power but it was just scraping by on the power needed. I activated the MRVN Automated Assistants and sent them to fix the hole in the ship, communication systems, and reactivate the generators along with the engines.

Years in the militia I became an engineer, a pilot, and a technician, on the field and off. I could handle repairing a titan to a transport shuttle.

4 hours later

I had finally given up the thought of the rest of the crew being ko'ed as none woke up. The life support system was finally at 100% and the engines and thruster where almost FUBAR'ed as far as I could tell. Then I activated the distress beacon as the short range systems got up. But I reframed from doing so, to avoid the IMC.

4 Months later

After an extended time of being alone I received a distress call.

"This is the colony of Shanxi. We are under attack; I repeat we are under attack." I never heard of a colony named Shanxi, but I wasn't going to sand by as a colony was attacked.

"This is Pilot Juan Martinez, of the Militia SRS, I'm on my way" I responded as I locked on to the origin of the transition and moved the ship to the planets orbit.

I was happy that the last 4 months had been productive as I finally brought the ship's AI names Trusty, similar to spyglass, to command all the MRVN Automated Assistants and specters combat robots and control the prototype titans. It also gave me a field promotion to Captain of the ship, Final Stage.

I ran to My Vanguard-class titan to get set for a combat drop. I was using a Scorch lead-out, to ensure that I got most of whoever or whatever was attacking the colony

We got to the planet and I was instantly dropped with my titan on the enemy's makeshift camp.

Once I landed I threw two canisters of thermite gas around the camp and shot one with my T-203Thermite Launcher and the other with a firewall charge. This instantly took care of most of those in the camp, at least the ones who weren't running. They weren't human, they were avionic in nature from the looks of the runners.

I switched to the Tone load-out and jumped out of my titan. "LG eliminate anything that isn't Militia while I check for any intel." I told my Titan, and received an 'Understood' from it. I moved thru the camp looking for any intel that could tell anything about these things. I tagged a cache of weapons and another of armor for pick up. To study the weapons and revers engineer them to incorporate them into my arsenal. It was after killing one of the aliens did I see that they had some holographic thing on the right arm. I proceeded to hack it and backtrack to the other bodies and extract anything I could.

"Trusty, have you attacked the enemy vessels," I asked the ship AI

"Yes, pilot I have," It replied.

"OK I want you to start all cyber-warfare you have and copy every piece of information you can, and disable the ship's comm-systems if you can. If that doesn't work then blow their hangers and engines," I told the AI.

"I have disabled 5 of the 15 ships and have destroyed 4 that tried to escape, or retreat," it responded. "Their weapons are almost ineffective to our shields, and ours bypass theirs easily," It informed me.

3 Days later

After my titan and I were picked up and got to Final Stage, "Alright Trusty, what did you translate or decrypt," I asked it.

It brought up two pictures of the galaxy. "Their map does not match ours, which gives me two theories," he explained. "first we traveled beyond our galaxy, and found an exact replica of humanity. Or using both warp and the phase shift, moved us into a different realm of existence."

"Okay, bookmark that for later. I want to hear about these Aliens," I said.

"Understood, will bring it up later," He said as one of the maps disappeared. "The aliens we have fought are called Turian, and they make up most of the military of the Council, and this is council space," He stated as a portion of the map was outlined. Another area was outlined and Trusty then stated "this is Terminus space, a lawless area with many species clamming in there, some people are considered warlords."

Then I read information of all races the Council met.

Rachni- Extinct, Bug-like, hostile.

Yahg- Quarantined, eight eyed humanoids, predator, hostile.

Batarian- four eyed Humanoid, slavers and pirates.

Vorcha- humanoid, 20-year lifespan, hostile.

Krogan- Giant lizard like, x2 of every organ. Note: will be hard to kill, test an anti-titan weapon on it.

Quarian- live in sanitized environment suits, weak immune system, Dextro-protein based.

Geth- Machine made by Quarians, drove out creators from homeworld.

Volus- live in pressurized bodysuits

Elcor- four-legged alien, says its emotion before sentence.

Drell- Reptile-like humanoid.

Hanar- jellyfish like creature.

Salarian- warm-blooded Amphibian humanoidish, less than a 40 years' lifespan.

Turian- avionic in nature, militaristic government, Dextro-protein based.

Asari- blue to purple Humanoids, monogender: female, long lifespan.

I laughed as they stated that Dextro-protein based food was toxic to non Dextro-protein based creatures and vice versa. They all had a strong allergy to the opposite protein.

"Trusty, can you find the Citadel's coordinates, how long should the travel be," I asked the AI.

"About Three days, Captain" he told me.

"Alright, drop some mines near that thing those aliens use, Relays I believe the call 'em, then we warp and speak with the Council of theirs," I ordered.

"Understood sir," Trust replied.

AN: This will be my interpretation of Mass effect, also I have all three games (+dlc's) but haven't played them all. I have played both TitanFall and TitanFall 2.

The Harem will consist of FemSheperd, Tali'zorah, Liara, and Ashley. note this story will be from First contact to the events of ME1 only.
