More information on Super Street Fighter 4's Tournament Mode DLC
• Tournament Mode is a head-to-head in single-elimination tournament with brackets, with works with 4 or 8 players.
• You can watch other tournament matches in progress while you're waiting for your turn and voice chat. Players competing can hear you as well, but if it annoys you, there's a mute option.
• To help with lag, spectators will be a little bit behind the actual match that's being played.
• Tournament Mode works with SSFIV's extensive recording feature.
• There are no battle points or rankings, but Tournament Mode will give players unique and special online titles, which can be won and lost from other players.
• Like SSFIV's other online modes, character selection is double-blind.
• Tournaments will continue on even if a participating player drops out.
• While the max amount of people a tournament can hold is 8 players, a 9th person can be there as the host. If the host drops, another will be found.
