The game is pretty much gore-free, even though most of the action involves killing people and blowing stuff up. There is violence aplenty and destruction is delivered in many forms (lasers, grenades, bullets, rockets, tanks, etc.), but there is no blood.
The game really seems designed for online multiplayer: Battlefront II supports 24-player matches on the PlayStation 2, 32-player matches on Xbox, and up to 64 on a computer. The multiplayer action is heavy on team-based modes in which one side must overrun the territory controlled by another, but the game also has the old standbys like capture-the-flag and deathmatch. Ultimately, there isn't much story here, and while the controls are relatively simple, so is the action. There's a lot more button-mashing than careful, controlled fighting and maneuvering, and fighting grows repetitive.
