In a team battle you have 3 options: Co-op with COM (1P + COM1 vs. COM2 + COM3), 2 Players Co-op (1P + 2P vs. COM1 + COM2), 4 Player Team VS (1P + 2P vs. 3P + 4P).
When two players on the same team make a chain at the same time, it becomes a 'Synchronized Bonus'. This will help you generate 1.5 times the Shadow Pieces to send to your opponents.
