ARES System Manual: ATOS Arena Protocol

ATOS/A (Arena) is a planned server product intended for use in setting up designated combat areas. It will provide scoreboard functionality for various classic first person shooter game modes, like team deathmatch and capture the flag.

ARES sends and receives some ATOS/A messages to report kills to other ATOS clients. Disabling baseband.arena will prevent the receipt of these messages.

See combat for more information on the ATOS combat system used by ARES and other NS products.
