Criticisms:
1. No keycard found in the (-massacre-) experiment room, therefore no director office access, and no victory
2. Subject 0-H is a tad bit overpowered, faster than player's sprint as well as killing in one shot.
I hope you are able to improve these, and I get the point of the subject is to be overpowered but jesus christ dude calm down

Interesting description, worth a try
