Now on with the main chapters, sorry to disappoint you on how I can't continue on the previous Lost Chapter as I was transitioning from writing this story from tablet to PC, as writing on keyboard is faster than typing on a touchscreen. If you are tired of waiting and want some brutalizing, I suggest you may read my other crossover; Doom DXD if you want some action and quicker updates as I work on it faster compared to TSOD, so don't leave and lose faith on me as I'm working on two stories at a time. I'm not good with non-combat dialogue than combat ones though.

Lambda's Chamber

Unspecified Time

The door opens revealing a dark large room with computers lighting around the place. It seems the room is empty for some reason as there was no human activity or someone works there. Leseath knew this kind of situations always have a surprise or anything unexpected as large rooms are bad omen to her. She then saw a pod where Lambda is with a marking of an orange lambda symbol that's quite different as there are no White Fang markings on it. She began to approach the terminal that controls the pod's operations and activated it. The terminal displays a message that seems to be urgent.

'PROJECT LAMBDA'

If you are reading this then you might be our last hope as the White Fang killed all of the Resistance personnel who worked on Lambda as they want to use Lambda for their evil uses. Please free my work that I've done in the last eighteen years only to be taken by White Fang and forgotten as everyone was executed around the base. I've made sure that no White Fang goes here and activate Lambda for their cause since the terminal here only accepts human users than Faunus which they are plenty of and no human works for them except the infamous Roman Torchwick who don't even know this base existed. Don't worry about Lambda since we've made her obedient on the first person she sees to protect from. Hurry before the White Fang knows you there and take our work for their lost cause. On the behalf of the Resistance we'll give you full access of this terminal as long you keep her safe. Also don't go looking for us as we go in our separate ways now as we forgot our bloody past back on Earth.

Dr. Gordon Freeman

Lead Scientist

The message also contains notes of Lambda as they made her during the past years. She then uploaded to her pip-scroll for future reading. The terminal shows another option which reads 'Project Info' which she clicked on it.

'PROJECT INFO'

Lambda is a vat-grown human since making an super-android is costly and inefficient as they are machines that don't adapt like humans do. They also can't seem use Aura as they are inorganic machines that have only preprogrammed personality that imitates humans with perfect score on Turing test that makes them passable on human society. They are also susceptible to Electro Magnetic Pulse like most machines do which they didn't have on this world as they depend on Dust rather than nuclear technology which we perfected on our world. However what separates them is the usage of Aura and being a real human, which androids lack. Aura works in mysterious ways as they enhance its user many ways that even high-spec machines won't able to beat a skilled Hunter in a fair fight; we proposed to start Project Lambda. Gordon suggested it as he was the leader of the project and was interested in defeating Atlas kingdom in biotechnology as they focused in production of robotics. Lambda has minimum cybernetic implants in order to make her Aura more effective but she's still dangerous as we enhanced her to be a super-soldier in defeating Atlas when the time comes as peace won't last any more as the White Fang continues rallying more members to their cause.

Dr. Ravenholm Gilbert

Project Supervisor

Leseath reads on more information that somehow related on Red Forest group that made Lambda and the base itself. Most of its data of Red Forest were hastily deleted as they don't want anyone finding their location that easily as White Fang were after them. She then found an option that says 'Start Lambda Activation' at the screen, she then activated and the chamber alarms as the pod slowly doing its job to free Lambda. For some reason, it triggered a whole base alarm, alerting every White Fang soldiers and the scientists.

'Oh, forgot to lock the door. There goes the element of surprise.' Leseath sighs.

Vance came in along with other scientists with some reactivated droids.

"My god what are you doing?" A scientist gasps as he saw the unlocking of Lambda.

Vance began to talk Leseath.

"You... You did it don't you? Gordon knew that someone will free Lambda as we tried to deny her from White Fang as we pretended she didn't exist, but you did it."

Leseath looked around and saw dozens of scientists and guard droids at the entrance.

She began to talk.

"So, what are you doing here? You want to kill me for freeing someone?"

Vance shook his head and gave Leseath a pair of red crowbars that somehow has an orange lambda logo on it.

"So? What's this? What are these crowbars do?"

"Her weapon, Gordon prefers crowbars since he's more proficient with it and has utility uses like prying doors and breaking crates, and maybe he can do the same with her." Vance replied.

"So, this Gordon knew how to fight despite being a scientist with a crowbar?" Leseath answered.

One scientist breaks their conversation.

"Uh, we got less time here, the White Fang are coming sooner as we expect, the droids might hold them off but we are still at disadvantage here."

Leseath however used her pip-scroll to drop most of the things she looted earlier from the soldiers and gave the unarmed scientists with her spare gear taken from them.

"Here, take these. I don't need it anymore but you guys need it." All of the scientists nodded and took everything and equipped all of the dropped gear.

"Thank you for helping us, but may I ask, where you keeping all of those stuff you carry?" Vance questions Leseath on where she got all the loot.

"It's a long explanation but we have no time for that as the White Fang are coming to get us! Everyone, create barricades so we can have an advantage here since this room has only one way from here." Leseath ordered the scientists to make barricades for impending attack.

Vance however pressed something on the terminal and opened a secret door at the wall.

"You take Lambda; we'll hold them off here as we retake the base from them. Gordon trained us for this kind of situations, so leave us." Vance loaded his gun along with other scientists and some androids as well.

"If you say so, but get out of here alive if you can." Leseath saw the pod was opening.

The pod containing Lambda opens with smoke coming out of it and a naked female opened her brown eyes for the first time. She has dark orange hair with fringes on front and rather slim body from her time inside the tube without physical activities during her life.

"So is she friendly?" Leseath asked Vance.

"Well, she is friendly but she is confused right now as she woke up from her long sleep in there so you'll have to convince her to come with you." Vance replied.

"So, is she a robot or something? Like one of those monotone people who has little or no personality at all?"

"Good thing you asked. She's no robot but a fully living human being that was created for warfare originally, she's not like most cold people who says one sentence at a time and Gordon interacted her to make her a bit more human-friendly and not cold. Go on, talk to her."

"Well, here goes nothing." Leseath goes to Lambda.

Lambda's First person POV

Dark, Darkness was the only thing I can see during my time here, it seems that I've been kept for so long without human interaction since Gordon left. I wonder what happened to him and this place. When suddenly someone freed me from this dark place and I began to wake from my endless slumber.

The water around my pod began to drain its contents and the screens opened, freeing me from this dark place that I've living from all my life. I gasped as I breathe my lungs outside from the pod.

I began to look around the area around me. It seems this place has more people in the room along with unfamiliar scientists and a girl who's somehow ordering them to barricade this place. The girl saw me and gave me a pair of crowbars and some clothes.

"Here, Gordon wants you to have these and also you might want to get dressed don't want you going around naked." The girl continued ordering some people to prepare from something.

"W-who are you?" I asked

"Name's Leseath and I am your caretaker since I've already activated this to free you. And this Gordon Freeman entrusted you to me don't know why but living inside in that thing makes to little bit strange. Do you have another name besides Lambda? If you want I'll rename you." Leseath replied.

"No, I'll stick with Lambda since it's my name originally."

"I respect your decision but will you get dressed already?"

"I don't know how to put this. Please help me Leseath."

Leseath nodded and began to fiddle something on her device or was it? Suddenly I began seeing myself in long sleeved white armor with baggy pants and combat boots. Leseath began to say something.

"Look, if you know how to fight then they are coming and we need to escape this facility. You were born with combat skills with it don't you?"

I nodded and equipped myself with a pair of crowbars and swung a few times to get used to its weight, then a pressed a button on it and switched into a pair of submachine guns.

'Nice.' I began to switch it into crowbar from and attached it in the back ends and turned into a double ended crowbar-staff which I liked.

Leseath looked awed of my weapon's transformations. I wonder what made her amazed. She began to talk to me after getting used on my weapons.

"Look, we'll need to get out of here alive. Don't worry about the scientists, they've got our backs and we'll go forward straight to the exit, got it?"

I nodded and followed her to the secret door leaving the scientists behind.

Leseath Third Person POV

White Fang Base

Night

Leseath and Lambda goes in the secret exit of the chambers leading somewhere around the base. Outside they've saw an inactive Paladin battle-walker parked nearby the exit that was being manned by a White Fang pilot. Leseath shot him before he entered the machine which also alerted nearby soldiers and returns fire at her. Lambda began to switch into SMG mode and gave suppressing fire at the soldiers. Leseath got the hint and then moves quickly at the inactive walker in Bullet Time evading stray bullets as she moved towards the cockpit.

"Sweet mother of robots, let's tango terrorist bitches!" Leseath closed the cockpit and started the walker.

The pip-scroll displayed an instruction manual to help her how to operate this machine. She then caused a massive chaos around the base, contradicting her promise earlier.

"Screw being a pacifist, I've got a big robot to play with." She then used the mini-rockets of the battle suit, destroying enemies around it and causing massive collateral damage around the base. She activated the smokescreen and used the battle suit's infrared vision to kill the soldiers guarding the exit.

She grins and used the battle suit's twin auto-cannons to decimate every single White Fang in the area.

*THUMP CHAGGA THUMP*

*BOOM*

Screams of soldiers can be heard as the mecha destroys them all. Lambda finished the rest of the retreating soldiers by mowing them down with her submachine guns and moved quickly to Leseath to support her.

"Let's get out of here! Let the scientists clean up this mess and follow me to the exit. We'll need to lose the heat first." Leseath ordered Lambda to follow her which she complies and mounted her battle walker, and moved towards to the forest with White Fang chasing them deeper in the forest.

No author's notes at the time, other than the shorter chapter than usual 3000-4000k. Sorry if you are expecting bigger update, but I will make it bigger in the next chapter in a week.
