GNU ACM is a distributed aerial combat simulator that runs on the X Windows System. Players can engage in simultaneous air combat from different computers. Players fly jet aircraft (something close to either an F-16C Falcon or a MiG-29 Fulcrum) equipped with radar, heat seeking missiles and cannon.
GNU ACM is a slighty modified version of the original ACM made by Riley Rainey at WebSimulations.
The main discussion list is <email@example.com>, and is used to discuss most aspects of ACM, including development and enhancement requests, as well as bug reports.
There is a separate list for general user help and discussion, <firstname.lastname@example.org>.
Announcements about ACM and most other GNU software are made on <email@example.com>.
