Co-Op Missions

Co-Op Missions (previously known as simply Co-Op) is a PvP co-op experience in DICE's Star Wars Battlefront II where four real, human players play with and against AI-controlled players in large-scale battles with unique scenarios. Players can spawn as reinforcements, heroes, and vehicles to change the tide of battle. Co-Op arrived on September 25, 2019 as part of the Cooperation Update.

Co-Op launched initially featuring only the Clone Wars, but The Rise of Skywalker Update on December 17, 2019 added the First Order–Resistance war to Co-Op and The Age of Rebellion Update on February 26, 2020 added the Galactic Civil War.

Overview
In Co-Op, four players team up with each other, as is in traditional co-op modes, to fight alongside with and against teams of AI bots. In addition to standard troopers, players (and AI) can also spawn as reinforcements, heroes, and vehicles. Players can also earn XP and progression for these units. Co-Op features all three eras of Star Wars: the Clone Wars, Galactic Civil War, and First Order–Resistance war.

As of the Age of Rebellion Update, attaining 50 kills as each of the default trooper classes awards players with new weapons: the E-11D, T-21, DL-18 and the Cycler Rifle.

Objective
In Co-Op, players can choose their faction to play as and play games in their respective eras. In a game, one team plays an attacking role while the other team plays a defending role, which depends on the map being played on. The attacking team must capture one Command Post in a sector in order to advance to the next sector before time runs out, while the defending team must prevent any of their Command Posts from being captured by the attackers.

The first sector has three (3) or two (2) command posts. Then all sectors after that have two (2) command posts, except for the last sector which has one (1). Only one command post must be captured for the sector to fall. Once a sector falls, the attackers push forward and advance on the map while the defenders are forced to fall back. If the defending team is able to successfully prevent the attackers from taking a sector within their time limit, they win; if the attacking team succeeds in capturing all sectors from the defenders, they win.

Trivia

 * Co-Op is very similar to the PvP mode Turning Point from DICE's Star Wars Battlefront. In Turning Point, a team of attackers would have to capture one control point at a time in order to secure a sector before moving onto the next sector (or set of control points), much like in Co-Op. This is also similar to the Operations mode from DICE's Battlefield 1 and Breakthrough from Battlefield V.
 * At its launch, the AI in Co-Op were only able to use Chewbacca, Yoda, Bossk and Darth Maul. This was due to a bug where the post-launch Clone Wars heroes (Grievous, Dooku, Obi-Wan and Anakin) were locked for them. This was patched in the October 2019 Patch.
 * Prior to the Another Night on Endor Update, which brought faction selection and defending on these maps, each map had a unique scenario:
 * The Republic would attack on Trippa Hive and Tagata.
 * The Separatists would attack on Kachirho Beach, Cloning Facility and Theed.
 * Discoveries within the games' files indicated that there were plans to have maps where the positions of attack and defense were reversed.
 * A Crait map for Co-Op was also discovered in the games' files, but was never completed and is thus unplayable.
