Thank you so much!
The AI is a bit janky, it was the best i could do in the given time frame. Haven't done too much enemy AI before...
The computers would eventually lead you to Daniel Gray's computer where he mentions what room the key is.
Since you say you found Murphy's computer, i assume that's where you got stuck. In Comlaint.txt, he mentions Pavlov leaving her paperclip in Lab 3. He also mentions she has everything there, implying there's even a password to her computer. There you find passwords to Frings and Grays computers. That's the most i'm willing to tell you tho >:)
