- TRIVIA -

The DUO Kit was released in February 1998.

Area 51 video was recoded using the Maximum Force system, so Kronn Hunter mode no longer works properly (this is an example of an undocumented 'feature').

An Area 51 / Maximum Force DUO machine was shown at the 2004 classic arcade games show 'California Extreme' in San Jose, California.
