Combine Labs is filled with a constantly churning mass of professors and grad students. The building is immense, with several floors and at least one basement filled with different laboratories.
You look over the directory for familiar names.
Room 16 - Engineering Lab (After unlocking through Hacking)
Room 30 - Open Computer Lab (If any of CS110)
Room 112 - Cybertechnology Lab (If you've heard about it from Boris)
Room 305 - Dr. Amundsen1
Room 309 - Professor Evans (If you've heard about him from the Coding Assistance quest or the Computer Lab Coffee Machine guy)
Room 412 - Dr. Myers2 (If you've heard about him from the Quad or Andrea the Grad Student)
Boiler Room (If you've heard about it from Shard, Lo, David or the drunk Third Eye)

This office is completely trashed. Computers, chairs, and paper files have been thrown everywhere. More disturbing, however, is the staring eye painted on the wall with what you hope is red paint.

Strangely, the whole stack seems to deal with one student.
You found: Arthur J. documents
2 If you gave Dr. Myers his sample:
This lab seems to be empty and locked. Doctor Myers apparently hasn't gotten back yet.
