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 grabbed out the given document and read it

The Document: “The true size of these subjects cannot be estimated, nor presumed due to their illusive nature. Despite originally resembling Ball Pythons, subjects "Guido" (sG) and "Rossum" (sR) bear resemblances to other species of Python. Subject sR seems to have mandible features from the Woma Python, with sharp, backwards-facing teeth designed to grab and hold prey. Unlike it's sibling, sG resembles more Pit Vipers, with a visible extra set of heat-sensing pits and long venom-injecting fangs. Both subjects display scleral hemorrhaging, an unusual green pigmentation in the iris', and a severe sensitivity and aversion to light, seemingly relying on movement and the body heat of targets when hunting.”

You then eyed at a highlighted word "Behaviors" which a red writing (likely written by Chekhov) that says "EXTREMELY IMPORTANT PART!!!" followed by a sticky note that reads

The Sticky Note: "I swear to god kid, if you get hurt then the others will blame me for Gross Negligence! THEN YOU'LL OWE ME. -Chekhov."

You read the Behaviors PART of the Document

Document: “The subjects appear to burrow away from main areas the team roam, hiding in ceilings with duct or the plenum of different floors. The size and weight of the two roaming these areas have created visible damage, with teams noting how they're alerted to the subjects' presence due to seeing large holes scattered around the ceilings. From encounters, it's been deduced that the subject appears to be extremely light sensitive ambush predators, explaining the subjects aversion to roaming rooms our expeditions go through. It's been noted that despite this, when a floor experiences a blackout, the subjects will still not roam the floors. It's assumed that the subjects still are careful of going out in this case, potentially knowing how the lights are sporadic within the facility.

Teams have noted that the subjects are extremely aggressive towards anything within sight that moves, seemingly only striking when feeling threatened. Teams are advised to watch the holes in the ceiling, and avoiding being seen by the subjects to prevent accidents.”

You closed the document and you keep walking searching for parts until...

"Hissss....."

You heard that... could it be... Guido and Rossum... you looked up and...

Infected Rossum: "HISSSSSSSSSSS!!!"

Rossum's head came out the ceiling and attempted to bite you but it missed to attack you as you dodged...

You encountered... Infected Guido and Rossum
