Area 54

Area 54 is an isolated facility in the Nevada desert belonging to the autonomous agency E.R.T.D..

On its exterior, Area 54 appears to be a private airstrip., but its three 'hangars' actually conceal a research installation that goes down many levels.

Area 54 was active between the 1950s and 2003, when E.R.T.D. was shut down.

After discovering the Land Military Mini-Con Team in 1959, the E.R.T.D. brought them to Area 54, at one point putting them through a field test outside the base. The Mini-Cons escaped and made it to the nearby town of Stillwater, but were quickly recaptured.

In 2003, the E.R.T.D. managed to capture the Air Defence Mini-Con Team as well, and brought them to Area 54 to be turned into weapons like the Land Military Team. However, the Mini-Cons woke up and hacked the Area 54 mainframe in order to learn about their other Mini-Con prisoners. They then escaped from the base through a conveniently huge air duct.
