You are a human child, working for the Agents at INNOVA after meeting them... at the floors bellow you were collecting parts for Chekhov...

You then grabbed out a document and read it

The Document: “The subject resembles a frilled dilophosaurus, though is notably smaller than other subjects. Measurements for this subject are particularly tricky, multiple reports of an inability to draw near the subject or accidents from attempts have made specifics difficult to obtain. Chains still remain on various limbs, showing evidence of previous teams (failed) attempts at restraining them. It appears the head of the subject has been eroded away, leaving only bone and muscle. This also seems to have exposed a split jaw, allowing them to wield a fierce bite. The spikes along the subject's back appear to have experienced rapid growth, growing to a slender, uncomfortable size.”

You then eyed at the IMPORTANT PART, behaviors... and you read it

Document: “Often when encountered, it is deemed docile. Many have noted only knowing the subject is present from the cave it resides in. Upon looking into the cave, it seems as though the subject is comforted by the enclosed, quiet space. Teams have also noted a lesser response to visual stimuli. The subject seems sensitive to noise, becoming hyper-agitated in noisy environments. Expeditions have proven that the sounds produced from failing an objective, or even more so the sound of the core machine being emptied of malachor have been deemed loud enough to send the subject into a hunting state. While the latter is deemed unavoidable for a successful expedition, the former, when properly avoided, can keep teams safe for longer when the subject is present.”

–When the subject is roaming, it's been assumed that they mainly rely on motion-based vision and keen hearing. Some members of our expeditions have even documented being able to sneak by the subject by keeping completely still. Though on the other hand, running near the subject will result in them hearing your location clearly. The subject is also known as the fastest, only dampened by their difficulty turning.

You sighed and noticed a hole... and you went to do an objective... and you failed so many times and...

"REEEEEEEEEEEEEEEEEEEEE!!!"

Uh oh...

It came out and it looked at you as it screeched, you encountered Infected Fizzle
