Walker Assault

Walker Assault is a forty-player game mode in DICE's Star Wars Battlefront that centers around Rebel Alliance soldiers calling in Y-Wing bombers to destroy Imperial AT-AT walkers. In order to call in their Y-Wings, Rebel soldiers have to activate uplinks scattered around the map and defend them from Imperial forces.

Rebel Alliance
The Rebel Alliance must destroy a group of incoming AT-AT walkers. In order to gain the upper hand against them, they must call in aerial Y-Wing strikes to lower their powerful shields. The ability to launch these strikes is governed by uplink relays scattered around the battlefield. There are always two uplinks active at one time with six uplinks being in the entire map, therefore there are three phases in which the Rebels must keep the uplinks online. The longer the Alliance controls a relay, the more Y-Wings can be brought to bear on the AT-ATs. Each Y-Wing gives the Rebels 10 additional seconds to attack the walkers. After five minutes of the uplink phase, the Y-Wings strike the walker. Once a Y-Wing has struck, the AT-AT's shielding is temporarily lowered and the walker is vulnerable to concentrated, conventional attack. After all Y-Wings have finished attacking, the next uplink phase begins.

Galactic Empire
The Galactic Empire must keep the Rebels out of the relays long enough for the AT-ATs to reach targeting range of the Rebel GR-75 transport. They should rally to defend vulnerable walkers when their shields drop. They also need to plan a defense for when the uplinks are offline to prevent Rebels from re-activating the uplink. On Endor, and Survivors of Endor there is only one AT-AT due to the large trees surrounding the area. On Bespin, there is only one AT-AT due to dense urban environment, making it near impossible for large vehicles to easily traverse the city. On the Scarif maps there are only two sets of uplinks, four in total, due to the maps smaller size.

Trivia

 * This is the only game mode where active AT-AT's appear.
 * When the uplinks are captured by the Rebels, a timer will begin on each uplink. If this timer successfully completes, one Y-Wing will be added to the Y-Wing stack. Each Y-Wing adds 10 seconds of vulnerability to the AT-ATs when their shields are down.
 * Walker Assault is among the most popular game modes.
 * This is one of the three base game modes that can never end in a draw, the others being Turning Point and Supremacy. The four expansion pack modes, Extraction, Sabotage, Battle Station, and Infiltration, also cannot end in a draw.
 * Walker Assault is one of the largest game modes in Star Wars Battlefront, the others being Supremacy, Fighter Squadron, and Turning Point.
