James Holiday

James A. Holiday was the transport controller stationed at the Communications Transfer point on Mars during the events of Doom 3. He was responsible for overseeing the transport of items throughout the Mars base, including the various dig-sites. Shortly before the demonic invasion, Holiday was asked by Ron Ridge what to do with a shipment of chainsaws that had been sent to Mars by mistake. Holiday suggested throwing them down the chasm near Enpro like other useless equipment.

Holiday was killed in the demonic invasion, possibly (and ironically) by a zombie wielding a chainsaw. His body and PDA are found in Service Room 2A of the Communications Transfer level. His PDA is needed to gain entry to the Comm Transfer Access.

Picking up Holiday's PDA also triggers an attack by zombies armed with chainsaws.
