Game Update 15: Galactic Civil War: Forces Under Siege is now live! The new update kicks the GCW up a notch by introducing "massive invasion warfare" scenarios to three major cities, as well as tons of new features to really spice up faction warfare for players.

The full feature list is available below:

New Gameplay:

Cities will display Imperial or Rebel banners and faction-specific NPCs, quests, terminals and pylons depending on which faction is in control

Added support for Factional Mercenaries. Neutral players can align themselves with either faction to participate in city conflicts and earn rewards

Mayors of player cities are able to set their city’s factional alignment from the management terminal

Fight battles within newly implemented Planetary Regions to determine which faction controls a planet

New Interactive Structures:

Defend cities by manning barricades and building defensive turrets

Assault enemy cities and take out defense structures and key enemy personnel with the might of AT-AT or Hailfire missile attacks

All New Profession-Based Quests:

Contribute to the battle with profession-specific quests that let players bolster defending or invading forces

Improve and repair defensive structures, revive fallen soldiers, heal fatigue, entertain demoralized troops, slice terminals, scout and sabotage patrol points, and more

Epic New Rewards:

Battle-specific quests such as manning barricades, building turrets and treating wounded soldiers, now grant tokens that can be cashed in for new rewards, including: faction-specific clothing including capes, cloaks and battle-scarred armor; Entertainer glow sticks; bombing-run binoculars; an upgraded personal shield generator and multiple new weapons
