Marcus is a variant of the UNSC Marine face bitmap found in Halo: Combat Evolved. It is found by opening a Halo: Combat Evolved map in Halo Map Tools. Not including Avery Johnson, there are six variants of face bitmaps. They are in DDS DXT1 texture format.
- To make the model for the Unnamed Bumblebee Pilot, Bungie artist Chris Hughes took Marcus and edited it to become female.
