How Classic Mode Works

Classic mode is the original Counter-Strike 1.6 format: two teams of up to 16 players face off across 30 rounds. Terrorists attempt to plant C4 at one of two bomb sites (A or B), while Counter-Terrorists defend or defuse. Round duration: 1 minute 55 seconds. Economy management, utility usage, and team coordination are as important as raw aim. First team to 16 wins.
