Override

Override was a six player match-made activity released alongside Season of the Splicer. It follows Mithrax, Kell of Light, Lakshmi-2, The Guardian, Zavala, Osiris, Ikora Rey, and Saint-14 as they breach the Vex Network with a Fallen technique known as "Splicing" in order to bring an end to the Endless Night.

Lore
After the Clash of the Chosen, the Last City was engulfed by the Endless Night, a Vex simulation created by Quria, Blade Transform as part of Savathûn, the Witch Queen's movements throughout the solar system. The Vanguard sought the help of Misraaks, who offered it in exchange for the House of Light's sheltering within the Last City. Agreeing to these terms, the House of Light is allowed to live in the abandoned Botza District while Misraaks teaches The Guardian the ancient Eliksni technique known as "Splicing" which allows the user to commune with machines. Using this new ability, the Vanguard hopes that it will bring an end to the Endless Night.

Gameplay
Override takes place in four locations around the solar system. All of them follow the same formula with the variation being found in enemy and boss types. Each location has its own simulated enemy race, which can appear in place of the Vex.

Overloading the Terminal
Override begins with the players walking up to a neon spiral of Vex constructs with enemies surrounding it. Killing enemies drops motes on the ground which need to get picked up and then deposited into the central terminal. Depositing the maximum of ten motes will spawn a crate of heavy ammo. Occasionally, a Champion will spawn in and will attempt to make its way to the terminal. If the Champion gets to the terminal, it will block the ability to dunk motes until it is defeated. During the dunking phase a portal will open up, allowing players into the Vex network. There will be a Champion within named Scytale that, when killed, will drops Data Spike. Players can pick up this Data Spike and deposit it into the terminal for a large amount of progress. This will happen once per phase.

Once the progress bar is filled by a third, the terminal will lock out and a large wave of enemies will spawn, led by two giant Ultras named Intrusion Detectors. All enemies must be killed to continue. Once the connection blockers are cleared, Vex nodes will spawn around the terminal, one of which will flash red and be damageable. Once three nodes are destroyed, platforms will spawn for the players to climb up in order to interact with the terminal and unlock it.

Once the terminal is unlocked, the waves will resume, with increasingly strong enemies that include Intrusion Detectors as well as Incursion Countermeasures, and the interaction point of the terminal being higher up. Completing this cycle three times will progress the activity.

Bypass Network Security
After the progress bar has been fully filled and the terminal unlocked, a vortex will appear in its place, leading to The Outer Nexus. Players will fall into the network and have to make their way through an obstacle course and enter a portal at the end of it. There, they will find the boss in a large, circular arena. Each boss has its own mechanics that suspend the fight twice, involving more Scytales as well as Soterian Minotaurs and rarely spawning a Network Anomaly.
