Master Matrix is a powerful computer in
Antarctica that will be built sometime between
1996 and
2188, and which will serve as the "operating system" for the entire
planet; the
LXM robots are connected to it and able to tap upon its files containing all human knowledge. It also controls the artificial environments inside the city of
New Camelot. In fact, it may or may not be located in or near New Camelot.
When the Space-Spawn invade Earth in 2198, one of their first actions will be to steal the Matrix, thus rendering the planet paralyzed and easily conquered.
It is unclear if the Master Matrix has anything to do with the Matrix nanotechnology constructed in the late 20th century.
