DOOM 3 Hints
Notes and Extras
1 of 2: You can kill Daniel Young in the Underground Junction to get a PDA, but it only has a useless e-mail on it. The same is true of Mark Ryan in the Underground Garage.
2 of 2: On the lower floor of the Energy Processing area on the way back, you have an opportunity to save a scientist who's being attacked by a zombie up on a higher walkway. If you shoot the zombie quickly enough, the scientist will get away and will open the storage locker further on in Energy Processing that has a fried code panel.
