Vex Offensive

Vex Offensive was a 6-player arena gamemode introduced with Season of the Undying in Shadowkeep. In this arena, players entered the Black Garden and fought off the Vex in order to stop more incursions from happening on the Moon. In order to play the activity, players had to own the Season of the Undying season pass.

As of Season of Dawn, Vex Offensive has been removed from the game and was replaced with The Sundial activity on Mercury.

Gameplay
There were three rounds to the arena. For the first two rounds players had to hold off waves of Sol Divisive Vex. After enough Vex was killed, Gate Technicians spawned, along with Fanatics and Supplicants. Killing the Gate Technicians dropped Void Craniums that Guardians had to pick up and use to destroy the Oracles. During the first round 6 Oracles spawned, and 12 spawned in the second.

During the third round the players fought a Minotaur named Crotheon, Gate Keeper. The mechanics from the first two rounds remained in the third, meaning players had to kill the Gate Technicians and get the Void Craniums. Players had to use the Craniums to take down Crotheon's shields, giving them 30 seconds to damage it before they recharged. During the battle, Crotheon rotated between three points within the boss area, meaning players had to move regularly.

Final Assault
The Final Assault version of Vex Offensive played the exact same, but the final boss was the Undying Mind rather than Crotheon. The only difference in the boss fight was that the Mind summoned Harpy Seekers during damage phases.

Loot Pool
Each round unlocked chests that gave either random rare gear, or Season of the Undying gear. This includes: The chests also dropped Vex Mind Components and Vex Chassis Components.
