The game even adds a commander system and squad system, making teamwork even closer and more competitive. The game supports up to 64 players online at the same time, while for the first time a scaled-down version of the map has been designed for 16-player skirmishes. Battlefield 1 sold over one million copies in its first week of release. Battlefield 1 was also a hit for several years, and as of September 2009, the update service for Battlefield 1 itself and the production of third-party modules had not completely stopped.
