Breakthrough

Breakthrough is a Crucible game mode introduced in Destiny 2: Forsaken. The mode was formally added to the game on September 25th, 2018 as a part of the Competitive Crucible playlist.

Synopsis
Two teams of four Guardians compete to capture a designated point on the map called the Breaker. Once the Breaker has been captured by a team, the mode shifts to attack and defense style. The team that captured the Breaker must assault a new set point, which is set as the opposing team's vault. If the attacking team manages to capture the Vault in time, they win the round. If the defenders can hold the attacks outside of their vault, they win the round. The mode is round based on a best of three basis.
