COM Map Asset

The com_map (believed to be "common map") appears to be dedicated to holding light data for the primary lights around the map. This asset is part of the D3DBSP system produced by Radiant so it has existed on every Call of Duty game so far.

Call of Duty 4 & Modern Warfare 2 & 3 & Ghosts

World at War & Black Ops 1

Note that "waterCells" and "burnableCells" were added in World at War and most likely left over in Black Ops 1, as they were subsequently removed in Black Ops 2. Also there is 0x10 unknown bytes before each cell entry, believed to be cell information.
