The Mechanical Diver is an enemy in Tomb Raider: Chronicles.
The Mechanical Diver is actually a man sitting abroad a yellow mini submarine that fires torpedoes.
As the Mechanical Diver can not be defeated in any way, Lara can only try to avoid it or use her ten Chaff Flares to create distraction.
If the torpedoes hit Lara, they cause fairly much of damage.
