Scientist (Doom RPG)

There are several, identical scientists in Doom RPG, and most of which aid the player as they travel through the different sectors of the UAC base. The only things that allow the player to differentiate between them are skin color and dialog.

Junction
In Junction there are two scientists that are nameless. One can be found next to a shop terminal, and one can be found between the entrances to Sectors 6 and 7.

The scientist near the shop terminal can restore the player's health to 100% for free. It's recommended that you take full advantage of his services in-between Sectors.

The scientist near Sectors 6 and 7 has several lines of dialog that it cycles through if the player continuously interacts with him. Nearly everything this scientist says breaks the fourth wall, as he pokes fun at the reused scientist sprites and the limitations of the phones the game was made for.
