The player's first assignment in Doom 3 is to find Jonathan Ishii. Sergeant Thomas Kelly assigns the player this assignment and sends him to the old communications facility, following reports that Jonathan was spotted heading in that direction. Sergeant Kelly instructs the player to bring Jonathan back unharmed.
When the player finds Jonathan, he panics and begs the player to let him send a transmission to Earth warning them of Dr. Betruger's experiments. Jonathan cryptically adds, "The devil is real. I know, I built his cage." Suddenly, the main portal in Delta Labs activates and demonic spirits come pouring out. Jonathan is possessed by one of these demon spirits (as are the majority of personnel throughout the base) and he becomes a zombie as a result, forcing the player to kill him. Jonathan is the first enemy the player faces in the game.
