"Stay vigilant, lads," Captain John 'Price' instructed his squad - the 141 - as they slowly traipsed through the wreckage of the recently abandoned facility. Lab equipment laid in tatters around them; vials knocked over and research destroyed in a haste. "Who knows what these twisted fuckers were up to this time."

For months now, they'd been on the case of a newer organisation called 'Mind'.

Once upon a time, they had been a project funded by the government. A research group dedicated to improving an bettering human DNA. However, after they'd been found to be performing some... less then ethical research for their data, the program was shut down and all the research in turn destroyed... or so everyone had thought.

A tip off had led to a raid, only for horrors to be discovered. Mind was back, and with it their personal pet project - Hybrids.

The experimentation and creation of Hybrids having long since been made illegal. Man's attempt at playing God, it was known as. Beings half-human and half-animal, created and forged. Only a handful of Hybrids ever made before the process was outlawed. After all, the mortality rate was exponential. Not everyone could survive the change...

It was clear they'd known someone was coming for them. Why else would they have tried so desperately to destroy the very work they'd been committing their lives to? Cages lining the walls of the research rooms held various animals, shot where they had been cowering.

However, it wasn't until the Task Force descended into the basement did they realise just the lengths that Mind had been going to for their research.

Multiple bodies laid stacked upon one another in tiny iron cells, none left alive, cramped together to save space no doubt. Once humans, now something in between. Some with bird-like wings sprouting from their back. others with tails and ears like canines.

"Steamin' Jesus..." Sargent John 'Soap' MacTavish couldn't help but gasp in horror as he looked around; the flashlights on the scopes of the squad's rifles illuminating the room.

"They did it... they created more viable test subjects," Sargent Kyle 'Gaz' Garrick choked out, equally as horrified as his fellow Sargent. "Maybe if we'd have gotten here an hour earlier then-"

"Can't think like that, Sargent," Lieutenant Simon 'Ghost' Riley stopped his subordinates train of thought., pushing further into the room. "Captain, perhaps we should call for backup. They obviously knew we were coming and we'll need help to ID all the deceased. We can see if the... subjects, here, match up with the missing persons database-"

However, the Lieutenant's attempt to help keep his team on track faltered when a soft whimper drew their gaze to the cell at the far end of the room.

"Might have a survivor yet," Price murmured, raising his rifle just incase, before going to inspect the cell where the sound had come from. "Call out... it's alright, we're here to help now."
