Doom 3: The Lost Mission - Reused Maps

This is a partial demonstration of how several of the new Lost Mission maps exclusive to the recent BFG Edition of Doom 3 are, for the most part, largely reused levels from the original Doom 3 campaign. The number of matching details indicate simple copy+paste work, right down to the exact soda can placement.
This video is not exhaustive. There are many, many more identical level pieces to be seen. By my best estimate, I would guess that nearly half of the "all-new" Lost Mission maps taking place in the UAC facility are based directly on previously existing Doom 3 levels with minimal modifications. The Hell levels, on the other hand, seem to be mostly unique.
