"As the primary armored vehicle of the Galactic Republic, the six-legged All Terrain Tactical Enforcer maintained an arsenal of six laser cannons and a powerful mass-driver on top while also acting as a troop transport."
The AT-TE walker is available for the Galactic Republic exclusively on Geonosis. The AT-TE is the largest vehicle in the game, and is not on rails, meaning that it can be freely and fully controlled by the player. Unlike most other vehicles in Galactic Assault, the AT-TE walker cannot be purchased for Battle Points and spawned into from the spawn screen; instead, it is manually entered in-game on the battlefront. AT-TE walkers are dynamically dropped on the map in the second phase on the Geonosis Galactic Assault Map. Another unique feature of AT-TE walkers is that they can be spawned on as an HQ by infantry troopers.
Mass Driver Cannon: This ability will fire the AT-TE’s main cannon causing damage to those in its blast range.
Tactical Support: This ability will provide support to nearby clones. Not only with it refresh their abilities, but it will also scan the nearby vicinity for Droids.
Ion Charge: The AT-TE transitions into Siege Mode allowing for Ion Charge to be fired instantly. Ion Charge is used to disable the Hardcells so they can be damaged by other weapons, and does come with a long cooldown.
Not counting certain "living vehicles" such as the Tauntaun on Hoth:Outpost Delta, the AT-TE walker is the first vehicle in the game to not be spawned into from the spawn screen, but instead manually entered into on the map.
A key difference between the AT-TEs and the Tauntauns, however, is that AT-TEs are dynamically dropped in-game throughout a match.
