The first season starts with Operation Rainbow Heist, starting March 18.
Season 1 will see a rework of the map Border, with season 2 reconfiguring Favela, season 3 getting three map reworks, and finally Outback getting a polish with season 4.
The system, and everything else, was discussed in a nearly hour-long livestream on Sunday, all of which is below.
Rainbow Six Siege first launched in December 2015.
