A/N: Prompt the Kink Meme. A a slight cross-over, AC/Dead Space. Not AU, I managed to come up with something that strays a little from cannon. Spoilers for AC: Brotherhood. I fixed some of the things that were bugging me, but I probably missed something so if you find anything, let me know!

"Desmond, what's wrong?"

He could barely hear Shaun's voice over his own heavy breathing, and the sound of his heart pounding in his head. Desmond gagged once, then twice before falling to his knees vomiting and gasping for breath. But the smell was so intense and thick that he could not make himself inhale. He was dimly aware of Shaun yelling in his headset.

"Desmond! Answer me! What the bloody hell-"

"Shaun." His voice came out raspy and harsh, trying to work through the sudden dryness he felt. Desmond took a deep breath through his mouth and tried to hold himself together, as he fumbled through his backpack. Sitting back against the wall when he found his phone, and tried as best he could, despite his shaking hands, to turn it on. "Pick up your phone."

"What?"

"Just fucking do it Shaun!" Desmond yelled without thinking. He gasped and looked around in a panic, hoping he didn't attract another one of things. Staying still for a few seconds and ignoring Shaun yelling at him as he demanded an explination. "Oh god oh god, shit... shit! S-Shaun!"

"Desmond, calm down and explain what the fuck is going on! Did you get captured? Are you hurt? What happened to the rest of the team-"

"Dead, they're dead! All of them- there were so many Shaun, those things... fuck! What the fuck are they! What was Abstergo doing, Shaun? Tell me you know somethin-" he stopped his panicked ranting when he heard a clicking sound. Frantic eyes searched around the corner, trying to see something in the dark corner of the hallway he was in. Desmond swallowed through the dryness and sank down again, hands working on his cell phone in a frenzy trying to work the camera. "I-I'm sending you something on your phone. Tell me what the fuck this thing is!"

"Desmond, you brought your phone!" Desmond almost feel Shaun's angry stare on him, and gave a breathless chuckle at the image. To think he thought that stare was by far the scariest thing he had ever seen... he would rather deal with an angry Shaun right now... "We told you not to do that, Templars can track you down!"

"How would they, they're fucking dead Shaun! Everyone's dead! Now shut the fuck up and let me take a picture of this thing I killed, and you can show it to everyone else and tell me what it is!"

"...what? What do you mean they're dead? I thought you mean our team is dead."

"They are, but so is everyone in the building... fuck, this thing fucking smells." Desmond gagged but managed not to vomit this time, and continued taking pictures. He figured one would NOT be enough. Walking around whatever the thing he killed was, Desmond took a couple of pictures, the entire time expecting for it to suddenly get up again and start attacking. "Okay... I'm going to send you some pictures."

"Alright. Desmond are... are you alright?" he sounded worried, and Desmond couldn't help but smiled at that.

"Yeah, more or less. It slashed me on the black, kinda hurts but nothing too bad. I'm more worried about bullets for this gun I found, I kinda need it."

"Not going to use your blade? Did you lose it?"

"No. No... I don't think I can kill one of these things with the hidden blade, especially since I have to get close to it and that's a bad idea... okay. I'm sending it."

He waited for Shaun to get the pictures, his back pressed to the wall like it would suddenly open up from behind him, and get him out of the Abstergo building.

"Alright, I got it..."

"..."

"...what the... Desmond, what is this?"

"I was hoping you could tell me... there's more, different kinds. We saw some dead ones in the lobby, and some of the ones the team managed to kill before they..."

"Jesus... fuck, what is... what the fuck was Abstergo doing!"

"Fuck if I know. If William knew about this, and still send us out, and I'm going to fucking kill him. We just lost a lot of people Shau-" Desmond stopped talking at the sound of something dragging on the floor. Shoving his phone in his pocket, and pulling the gun he had found out, he pointed it at the corner of the hallway the sound was coming from. The sound of the inhuman growling was loud enough for Shaun to ask about it.

"What was that?"

"Shaun... don't send anyone else. I'll... I'll find a way out of the building, but you can't send anyone else here!" Desmond could see it peering at him from the corner of the hallway, before it hid itself away. "Shit...this thing is fucking playing with me. You motherfucking-"

"Fuck that! Desmond, we're getting you out of there, just... let me call William, he-"

Whatever Shaun said after that was lost when the thing suddenly screeched at Desmond, running towards him on full speed.

"-knows a bit of what happ-" Shaun suddenly stopped when he heard a high pitched growled, and the sound of Desmond screaming, followed by gun shots, and something hitting the ground. "Desmond!"

"Aaaugh! Oh god... shit! Get up Desmond, come on..." the sound of shoes clicking on the floor informed Shaun that Desmond was running from whatever it was that was attacking him. "Fuck, it's chasing me!"

"Fuck!" Shaun searched through his contacts in his cell phone despite being told to never contact anyone with it. He would have to hang up on Desmond otherwise. "Come on you fucking piece of...Desmond, hide yourself and wait for us to come get you-"

Desmond screamed, and Shaun felt his stomach drop at the sound. That wasn't a scared scream.

That was a pained scream.

It was followed by a groan and a whimper, before the sound of clicking shoes came back, but this time it faded off. Shaun paled. Desmond didn't have his headset anymore.

"DESMOND!"

The last thing he heard through the headset was a high pitched growl and the sound of heavy steps running across the floor.
