Games in the Battlefront series normally revolve around two armies – the Galactic Republic versus the Confederacy of Independent Systems or the Galactic Empire versus the Rebel Alliance or First Order versus the Resistance – fighting each other on various maps. Maps take place in the Star Wars galaxy, with battlezones varying in theme and size. Across the battlefield are multiple "command posts" (objectives) that act as spawn points, and can be controlled by either the player or the computer. Units can spawn from any friendly command post, and vehicles regularly spawn at their respective command posts when destroyed. Units can capture neutral or hostile command posts by approaching them and standing within the immediate vicinity for about 30 seconds. The time to capture quickens with more friendly units within the capture zone. Some vehicles act as mobile command posts, and must be destroyed as they can not be captured. On some maps (such as Hoth or Endor), certain structures also act as command posts that can not be captured. Command post capturing works differently on certain campaign missions as well. Playable heroes and villains play a significant role in changing the course of battles.
