Dr. Martin

Dr. Martin is a minor character in Doom Resurrection. He is a colleage of Dr. Garret who works in the Delta Labs. He has special access to the Delta systems, including the tram system and the teleporters, which he grants to Sam after informing the protagonist that the dimension the UAC has opened a gateway to is in fact actually Hell.

When first meeting Dr. Martin, he informs the player that a monster bit him earlier, but that he thinks he will be alright. However, immediately after he has finished giving his access permissions to Sam, he groans in pain and transforms rapidly into a zombie, which the player must then kill. A chaingun can be found in his hiding place and can be collected after he dies.
