In the maps we made, there are 5 poles. When a team has captured 3, it's timer goes down. When it is reach 0, the team only wins if 3 poles are captured and not being uncaptured by the opponent team. Respawn are more and more slower with time, so it becomes more and more unbalanced on the field.
Another complicated thing to understand on the mode: when a team wins a round, it does not score a point. The team needs to win by the other starting point in order to win. If both team win a round, then it starts all again, but in 1 minute instead of 2. If both team wins a round, then it starts with 30 secondes instead of 1 minute etc.
Better to play instead of trying to understand I think
It is one of the most played mode at Nadeo a year ago. The basics are classic, but the evolution described above where brought after time of play and to enable easy creation of asymetric maps with a fair system. Like Siege, it has to be played some times to really get it, and I hope, enjoy it
